For producers operating sour assets, the commercial argument for investing in hydrogen sulfide treating is straightforward — but the magnitude of the opportunity depends on the specific asset profile. Here are the primary value drivers:

Converting Flared Gas into Sales Revenue. Every Mcf of sour gas that is flared rather than treated and sold represents destroyed revenue. For an unconventional multi-well pad flaring meaningful volumes because of hydrogen sulfide, on-site treating can convert that flared gas directly into sales gas — converting a waste stream into revenue while simultaneously reducing emissions.

Eliminating Sour Takeaway Dependency. Many sour gas producers in the Permian Basin and elsewhere depend on midstream partners to transport and treat their sour gas. This creates a structural vulnerability: when sour takeaway capacity is constrained — a recurring challenge in the Permian Basin as production growth repeatedly outpaces midstream infrastructure — operators face production curtailments or are forced to flare. On-site hydrogen sulfide treating removes this bottleneck, allowing operators to sweeten their own gas at the wellhead and inject it directly into sweet gas gathering infrastructure.

Enabling Gas Lift Without Sweet Gas Buyback. Gas lift is one of the most common artificial lift methods used in unconventional oil production in the Permian Basin. It requires a supply of compressed gas injected into the wellbore to reduce hydrostatic pressure and increase oil flow. When the produced gas at a well site is sour, operators traditionally must purchase sweet gas from a third party for gas lift injection — an expense called sweet gas buyback. On-site hydrogen sulfide treating eliminates this cost by enabling operators to sweeten their own produced gas and use it directly for gas lift.

Strengthening Environmental Performance. Reducing routine flaring and eliminating the use and disposal of hazardous chemicals are increasingly material to oil and gas operators’ environmental performance. Hydrogen sulfide treating technology that converts H₂S into non-hazardous elemental sulfur — rather than destroying it through flaring or disposing of spent chemical waste — addresses multiple environmental performance metrics simultaneously.

Common Hydrogen Sulfide Challenges and Their Consequences

The ChallengeThe Consequence
Hydrogen sulfide exceeds pipeline specificationGas cannot enter the sales pipeline; revenue is lost or gas is flared
Limited sour gas takeaway capacityProduction is curtailed; sour assets remain stranded
Flaring restrictions tightenOperators face regulatory exposure and reputational risk
Triazine scavengers overwhelmed at high hydrogen sulfide concentrationsTreatment costs escalate; performance degrades
No sweetened gas available for gas liftOperators must purchase expensive sweet gas buyback

Why Legacy Hydrogen Sulfide Treatment Methods Fall Short

Traditional approaches to treating hydrogen sulfide in natural gas streams — including triazine chemical scavengers and amine sweetening systems — were developed for a different era of oil and gas production and carry limitations that make them a poor fit for many of the sour gas challenges operators face today.

Triazine Scavengers. Triazine is the most widely used non-regenerative H₂S scavenger in the U.S. oil and gas industry. It captures hydrogen sulfide through a one-time, irreversible chemical reaction that produces Dithiazine — a liquid hazardous waste requiring disposal at a saltwater disposal well or licensed hazardous materials facility. Because triazine is consumed in the reaction, spent chemical must be continuously repurchased and the Dithiazine byproduct continuously disposed of. At the hydrogen sulfide concentrations common in the Permian Basin and Eagle Ford, triazine scavengers can quickly become economically unsustainable: the chemical becomes overwhelmed, efficiency degrades, and costs escalate rapidly with H₂S load.

Amine Sweetening. Amine scrubbing systems are effective at high volumes and can achieve deep hydrogen sulfide removal, but they require significant capital investment, skilled operations, and a stable, predictable gas feed. They are designed for gas plant and refinery-scale operations, not for the variable-volume, distributed-production environments typical of upstream oil and gas operations in unconventional plays.

Flaring. As previously noted, flaring converts hydrogen sulfide to SO₂, wastes a saleable commodity, and is increasingly restricted by state and federal regulation. It is a disposal method, not a value-creation strategy, and it creates environmental and regulatory risk rather than eliminating it.

Regenerative Liquid Redox: A Purpose-Built Solution for Unlocking the Value of Sour Gas Assets

Next-generation liquid redox hydrogen sulfide treating addresses the limitations of legacy methods by combining a regenerative chemical process with advanced automation — making it practical, economical, and operationally manageable across the distributed, variable-volume conditions typically found in the production of unconventional assets.

How Liquid Redox Works

In a liquid redox process, sour gas contaminated with hydrogen sulfide is directed into a treatment vessel containing specialized chemistry. Hydrogen sulfide in the gas stream donates electrons to the chemistry — oxidizing the H₂S into elemental sulfur, which precipitates out as a solid. The chemistry, now reduced, is routed to a regeneration vessel where exposure to air re-oxidizes it back to its active state, ready to treat more gas. The treated gas exits the system sweet, at non-detect hydrogen sulfide levels, and can be directed immediately to a sales pipeline, gas lift header, or fuel gas system.

Streamline Innovations’ VALKYRIE® system executes this cycle using TALON® chemistry — a non-toxic, biodegradable, patented reagent — combined with advanced process control and automation that manages the treating and regeneration cycle continuously with minimal field labor.

Technical note: Liquid redox is not a catalytic process. The TALON® chemistry actively participates in the reaction — accepting and donating electrons — and is then regenerated for reuse. It is a regenerative chemical oxidation process, distinct from both non-regenerative scavengers and true thermal-catalytic methods such as the Claus process, so less product is required to treat the same volume as an equivalent method.

The Byproduct Advantage of Liquid Redox

Instead of Dithiazine waste, the VALKYRIE® process produces Simple Elemental Sulfur — a non-hazardous solid listed by the Organic Materials Review Institute (OMRI) for use in organic food production. The byproduct can be sold or disposed of as non-hazardous material, eliminating the hazardous waste disposal costs that burden triazine-based programs.

Valkyrie Operating Envelope

The VALKYRIE® H2S removal system is engineered to treat across the full spectrum of conditions found in upstream and midstream oil and gas operations:

  • Hydrogen sulfide concentrations from trace levels up to high-concentration sour gas streams that overwhelm triazine scavengers
  • Gas flow rates from single-well pads to multi-well production facilities
  • The full range of operating pressures encountered from wellhead to refinery
  • Near 100% turndown capability without loss of efficiency as production volumes vary

This operating flexibility — the widest of any field hydrogen sulfide treating method — is what makes next-generation liquid redox suitable for the variable-volume, distributed-production environments of unconventional oil and gas plays.

Real-World Results: Unlocking Sour Gas Value in the Permian Basin

VALKYRIE® hydrogen sulfide treating systems have been deployed across the Permian Basin and other U.S. sour gas producing regions, with operators including Chevron and others among those putting the technology to work.

In a representative deployment, a Permian Basin operator used VALKYRIE hydrogen sulfide treating technology to unlock the value of its sour oil and gas assets. With on-site VALKYRIE treating installed at the production pad, the operator was able to:

  • Sweeten produced gas to pipeline specification and sell it directly into sweet gas gathering infrastructure
  • Use a portion of the treated gas for gas lift operations, eliminating sweet gas buyback
  • Eliminate routine flaring of sour gas at the site, reducing SO₂ and methane emissions
  • Expand the deployment field-wide as additional wells came online

The result was a sour asset that had previously required flaring or remained constrained by takeaway capacity being converted into a commercially productive, low-emission operation.

Is On-Site Hydrogen Sulfide Treating Right for Your Operation?

On-site liquid redox hydrogen sulfide treating is best suited to operations where one or more of the following conditions apply:

  • Sour gas cannot be commercialized due to hydrogen sulfide concentrations that exceed pipeline specification
  • Sour gas takeaway capacity is limited or unreliable, constraining production
  • Flaring restrictions are tightening and routine flaring of sour gas creates regulatory or reputational exposure
  • Gas lift operations require sweetened gas but sweet gas buyback costs are significant
  • Triazine scavenger costs are escalating as hydrogen sulfide loads increase
  • ESG commitments require measurable reductions in flaring and hazardous chemical use

For operators in the Permian Basin, Eagle Ford, or other sour-prone producing regions, the economics of on-site hydrogen sulfide treating improve substantially as hydrogen sulfide concentrations rise and gas volumes grow — precisely the conditions where legacy scavenger methods become least viable.

Treating natural gas streams for hydrogen sulfide (H2S) is a non-negotiable operational requirement for Oil & Gas producers in the United States. Hydrogen sulfide is highly corrosive to steel pipelines and compression equipment, and at elevated concentrations it presents a life-safety hazard to field personnel. Most natural gas transmission pipelines impose strict limits on hydrogen sulfide concentration, requiring producers to remove hydrogen sulfide before gas can enter the sales pipeline. Operators frequently compare Triazine vs. liquid redox treatment methods.

In producing regions where sour gas is common, such as the Permian Basin in West Texas and southeast New Mexico, as well as the Eagle Ford trend in southern Texas, the ability to treat hydrogen sulfide efficiently and economically impacts whether a sour gas asset can be commercialized.

This article compares two hydrogen sulfide treatment strategies for natural gas in the field: the triazine chemical scavenger (the traditional industry default) and next-generation liquid redox used in Streamline Innovations’ VALKYRIE® system. In the Triazine vs. liquid redox comparison, understanding the differences in mechanism, cost, byproduct handling, and operational complexity is essential for producers evaluating which approach best fits their assets and production profile.

What Is a Triazine H2S Scavenger?

Triazine is arguably the most widely used non-generative liquid scavenger for hydrogen sulfide treatment in the U.S. oil and gas industry. Chemically, it is a hexahydrotriazine compound, a clear to pale yellow liquid with a fishy smell. Triazine is usually mixed with other substances to bring concentration down to field strengths ranging from 20-80%, depending on the application.

There are two primary deployment methods:

  • Contact tower (scavenger tower): Sour gas is fed into a tower vessel where it bubbles up through the triazine liquid. As the hydrogen sulfide contacts the triazine in the treatment tower, a chemical reaction captures it and renders it harmless. Contact towers can achieve up to 80% efficiency in hydrogen sulfide removal.
  • Direct injection: Triazine is injected directly into the gas stream. This method is simpler to install but significantly less effective, achieving only 40% efficiency.

How the Triazine Reaction Works

Triazine removes hydrogen sulfide through a non-reversible chemical reaction: one mole of triazine reacts with two moles of hydrogen sulfide to produce Dithiazine and monoethanolamine (MEA). Because this is a one-time, non-reversible chemical reaction, the triazine is consumed in the process and cannot be regenerated. Once spent, the triazine must be replaced periodically and the spent liquid must be disposed of.

Dithiazine: The Disposal Problem

Dithiazine is the unavoidable byproduct of triazine-based hydrogen sulfide treatment. It has no commercial secondary use and is classified as a liquid hazardous waste. Disposal options are limited:

  • Injection into saltwater disposal (SWD) wells alongside produced water, if the SWD operator permits it
  • Disposal at a licensed hazardous materials facility

As hydrogen sulfide concentrations increase or treatment volumes grow, Dithiazine generation scales proportionally, meaning disposal costs can become a significant operational burden on oil and gas assets with high concentration of hydrogen sulfide.If you’re evaluating sulfide treatment strategies for high-H₂S produced water, don’t rely on theory, review the field data.

Chemical Handling and Safety of Triazine

Liquid triazine is typically transported in plastic totes to the well site or production pad. Field personnel encounter direct exposure risk when moving totes, maintaining contact towers, and servicing injection equipment. The U.S. Environmental Protection Agency classifies types of triazines as possible human carcinogens, and exposure can cause skin rashes and eye irritation. Chemical handling training and PPE requirements add to the operational overhead of triazine-based hydrogen sulfide treatment programs.

Triazine: Pros and Cons Summary

The benefits of using triazine for treating H2S in gas streams include:

  • Low upfront capital cost.
  • Zero air emissions.
  • Widely available in most oil and gas producing regions.
  • Skid-based units can be mobilized from one location to another quickly and easily.

Downsides include:

  • Efficiency degrades under high hydrogen sulfide loads.
  • Dithiazine byproducts require hazardous waste disposal.
  • Contact towers are typically only 80% efficient, direct injection only ~40% efficient.
  • Non-regenerative process, meaning frequent media changes.
  • Often requires use of other chemicals to mitigate negative downstream effects.
  • Contact towers (bubble towers) can be operationally complex and require frequent attention.
  • Can be costly when treating gas with high concentrations of hydrogen sulfide and/or high gas flow rates.
  • Worker exposure to chemicals at the worksite, potential health and safety concerns.

What is Next-Generation Liquid Redox for Hydrogen Sulfide Treatment?

Early generations of liquid redox hydrogen sulfide treatment suffered from operational complexity and inconsistent performance. Next-generation liquid redox systems, such as the VALKYRIE® platform from Streamline Innovations, address those limitations through upgraded chemistry and advanced automation, making regenerative hydrogen sulfide treatment practical across a wide range of field conditions.

The VALKYRIE H2S treating solution from Streamline Innovations utilizes relatively recent technological advances in automation control to create the “Next Generation Redox” system. The VALKYRIE system utilizes patented TALON®, our non-toxic, biodegradable Redox chemistry. Unlike triazine, TALON chemistry participates in a reduction-oxidation (redox) cycle that converts hydrogen sulfide into elemental sulfur and water, and then regenerates itself through exposure to air, allowing the chemistry to be recycled and reused.

How the Liquid Redox Process Works

The mechanism has two stages that operate in a continuous loop:

Reduction: Sour gas contacts TALON chemistry in a treating vessel. Hydrogen sulfide (H2S) is oxidized into elemental sulfur – a solid that precipitates out of the liquid.

Oxidation (regeneration): The chemistry is then regenerated with exposure to oxygen back to its active state, ready to treat more hydrogen sulfide.

The treated gas exits the system free of hydrogen sulfide (at non-detect levels), and the elemental sulfur is filtered, collected, and periodically removed. The VALKRYIE system uses advanced process control and automation to manage this cycle with minimal field labor.

Simple Elemental Sulfur™: A Byproduct with Value

Unlike Dithiazine, the elemental sulfur produced by Streamline’s VALKYRIE system is non-toxic and produces Simple Elemental Sulfur™, which has been approved by the Organic Materials Review Institute (OMRI) for use in organic food production. This means the byproduct can potentially be sold rather than disposed of — a meaningful difference in the total lifecycle cost calculation.

VALKYRIE Operating Range and Applications

A significant advantage of next-generation liquid redox over triazine for hydrogen sulfide treatment is its operating envelope. The VALKYRIE system is designed to treat across the full spectrum of:

  • Pressure ranges encountered across upstream and midstream applications
  • Gas flow rates from smaller single-well pads to multi-well production facilities
  • Hydrogen sulfide concentrations from low ppm levels up to high-concentration sour gas streams that would overwhelm triazine scavengers

This flexibility makes liquid redox suitable for a range of oil and gas hydrogen sulfide treatment configurations, including wellhead sweetening, field gas conditioning for gas lift operations, and fuel gas conditioning. Several leading operators, including Chevron and others, have deployed VALKYRIE units in the Permian Basin.

Next Generation Liquid Redox: Pros and Cons Summary

The benefits of using Next Generation Redox for treating hydrogen sulfide in gas streams include:

  • Treats hydrogen sulfide to non-detect levels
  • Regenerative chemistry — dramatically reduced ongoing chemical cost
  • Non-toxic, biodegradable TALON chemistry; improved field safety
  • Elemental sulfur byproduct is non-hazardous and potentially marketable
  • Widest operating envelope of any field hydrogen sulfide treatment method
  • Advanced automation reduces field labor and oversight requirements

Downsides include:

  • Higher initial capital investment than triazine scavenger equipment
  • Requires a power source for automation and controls

Triazine vs. Liquid Redox: Side-by-Side Comparison

The table below summarizes the key differences between triazine scavenger and next-generation liquid redox for hydrogen sulfide treatment in natural gas:

Upfront CostLowHigher initial capital
Best ForLow-volume, low H2S, short-duration applicationsHigh H2S concentrations; sustained production operations

Which Hydrogen Sulfide Treatment Method Is Right for Your Operation?

The right choice depends on the specific characteristics of the sour gas asset and the operational context:

Triazine scavengers may be the better fit when:

  • Hydrogen sulfide concentrations are low and/or volumes are small
  • The treatment needs are short-term — for example, during workover operations or temporary production testing
  • Minimizing upfront capital cost is the primary constraint
  • Midstream sour gas takeaway capacity makes wellhead treating optional

Liquid redox is typically the better fit when:

  • Hydrogen sulfide concentrations are high enough to push triazine costs to unacceptable levels
  • The asset is a sustained producing operation where accumulated chemical and disposal costs favor a regenerative system
  • Pipeline hydrogen sulfide specifications are stringent and require non-detect outlet levels
  • On-site treating is needed to enable gas lift, fuel gas conditioning, or other operations requiring sweetened gas
  • Reducing risks of field chemical handling risk and improving ESG performance are operational priorities

For most sour gas producers in the Permian Basin and Eagle Ford trend operating sustained production assets with meaningful hydrogen sulfide concentrations, next-generation liquid redox typically offers a lower total cost of ownership and better performance profile than triazine scavenger — even when accounting for the higher initial capital investment.

As operators extend their development beyond the established “fairways” of unconventional shale plays, they are increasingly encountering oil and gas resources containing high levels of hydrogen sulfide (H2S), otherwise known as “sour” assets. Sour oil and gas resources are especially prevalent in the Delaware Basin portion of the Permian Basin, located in New Mexico and West Texas.

Because it is poisonous and highly corrosive, sour gas presents a threat to both human health and infrastructure. When produced with crude oil, sour gas must be treated and transported off the production facility or flared for safety purposes. However, operators are increasingly encountering barriers to developing sour oil and gas resources in the forms of sour takeaway capacity and initiatives to eliminate routine flaring.

In this article, we cover the challenges operators face when developing their sour crude and natural gas assets and offer a solution to help them alleviate the constraints in an environmentally friendly way.


The Constraint of Sour Takeaway

Sour gas requires treatment before it can be distributed to residential, commercial, and industrial customers. Traditionally, sour gas has been flared or combusted to convert the contaminated gas into less harmful substances. However, flaring sour gas produces other pollutants such as sulfur dioxide (SO₂), which contributes to acid rain; volatile organic compounds (VOCs); and nitrogen oxides (NOx), which can react with particulates and sunlight to form ozone. Additionally, incomplete combustion may release raw H2S where it can accumulate at the production facility and present a threat to worker safety.

Instead of flaring sour gas, it can be treated and sold as pipeline quality gas. Traditionally, sour gas treating occurs downstream at a gas processing plant operated by the midstream partner. The contaminated gas must be transported using equipment that has been treated and coated to withstand the corrosive effects of sour gas, also known as sour takeaway. Sour takeaway, however, is expensive to install and even if it is available, downstream H2S treating capacity in many regions has not kept pace with the development. Both lack of sour takeaway capacity and downstream H2S treating bottlenecks create significant hurdles for operators.

Without a treating solution in places where flaring is not an option because of regulatory restrictions or voluntary emissions reduction practices, developing sour gas resources must come to a halt.

Debottlenecking – Removing Sour Gas Takeaway Constraints

Operators can debottleneck sour production by installing H2S treating capacity at the well site or production pad for “sweetening” sour gas, effectively removing midstream capacity constraints.

In our article, Gas Sweetening, Sour Gas Treatment Strategies by Volume, we identified the three primary categories of traditional gas treating methods for removing H₂S from produced gas, including (a) scavengers and adsorbents, (b) catalytic reactions, and (c) mechanical destruction or injection. These methods, however, have numerous downsides, including:

The Liquid Redox (Reduction-Oxidation) process converts H₂S into elemental sulfur and water vapor byproducts using chemistry (Reduction) that can be regenerated and used again with exposure to air (Oxidation).

Using a Next Generation Liquid Redox process, sour gas is directed into a treating vessel containing specialized chemistry and then exits the system sweet (without H₂S) into a gas sales line. The elemental sulfur byproduct is filtered out of the liquid, and the chemistry is then regenerated with exposure to oxygen. The regenerated chemistry is then recirculated back into the treating vessel to perform the reaction again. The regenerative nature of the chemistry reduces media changes, disposal costs and reduces chemical handling requirements on the well site.

The VALKYRIE® H₂S treating solution from Streamline Innovations utilizes relatively recent technological advances in automation control to create the “Next Generation Redox” system. The VALKYRIE system utilizes TALON® chemistry, our non-toxic, biodegradable Redox chemistry.

VALKYRIE technology is a true green solution, by reducing the flaring of sour gas and related emissions at oil and gas production sites by converting H₂S into harmless byproducts, including elemental sulfur certified for use in food production.  

The Streamline VALKYRIE H₂S removal system is the next generation of Liquid Redox (Reduction-Oxidation) to cost-efficiently help oil and gas operators unlock the value of sour gas resources and reduce emissions from oil and gas operations.

As oil and gas wells age, natural reservoir pressure diminishes resulting in a natural decline in production rates. Eventually, the well reaches its economic limit when lower production and net revenue no longer cover ongoing operating expenses. It is literally a race against time. Artificial lift methods, however, can extend the life of the well by boosting production and one of the most effective artificial lift techniques is gas lift.  

Gas lift systems inject natural gas into the well casing to assist in lifting liquids to the surface through the production tubing. Operators use gas lift when reservoir pressure declines, water cuts increase and gas-to-oil ratios (GORs) change over time.  

The primary barriers to using gas lift, however, include the availability of natural gas produced at the well site and/or if the produced gas is “sour” and contains high levels of hydrogen sulfide (H₂S). Sour gas presents serious threats to both human health and infrastructure, rendering it unsuitable for gas lift operations. 

Fuel Gas Conditioning – Eliminating H2S and Reducing Emissions  

In situations where sufficient gas is produced at the well site for gas lift, but it is sour gas, operators typically have resorted to purchasing sweet gas (not containing H₂S) from their midstream partner in a practice known as sweet gas buyback. The downside to this approach is that it tends to be expensive.  

Operators with sour gas operations can avoid the expense of buying back sweet gas by treating H₂S on-site. This approach not only ensures a reliable source of gas for gas lift operations but can also lead to cost savings and environmental benefits. 

In areas with sour takeaway constraints, on site field gas conditioning can also significantly mitigate or eliminate the flaring by sweetening sour gas and using it for gas lift and/or selling it to the pipeline. Avoiding the flaring of sour gas also reduces potentially harmful emissions, like sulfur dioxide (SO₂).  

In fact, leading operators including Taprock Resources and Franklin Mountain Energy are using VALKYRIE technology to reduce emissions by sweetening sour gas on site and using it for gas lift operations.

Hydrogen sulfide (H2S) is produced from the decomposition of plant and animal matter, with around 90 percent of H2S emissions being naturally sourced. Hot springs and volcanoes also release substantial amounts of H2S. Natural gas containing significant levels of sulfur is termed “sour” and requires treatment before it can be distributed to residential, commercial, and industrial customers. Untreated H₂S is typically flared for safety reasons and to convert it into less dangerous pollutants, but the practice still generates emissions.  

How Sour is Sour?  

Natural gas produced from oil and gas wells is approximately 70-90 percent methane and contains up to 20 percent of heavier hydrocarbons, including ethane, butane, and propane. Gas produced from an oil or gas well typically contains other contaminants, too, including water vapor, sand, oxygen, carbon dioxide, nitrogen, and in many cases, hydrogen sulfide.  

There is no one set definition of what constitutes “sour” gas, because concentration levels can vary widely from area to area. The Texas Railroad Commission, however, defines sour gas as having an H2S concentration of 100 ppm or more as noted in Statewide Rule 36, which provides  provides sour gas operating requirements to safeguard worker and community safety (source: Statewide Rule 36).

How Does Sour Gas Cause Emissions?  

Sour gas presents a threat to both human health and infrastructure. Sour gas production must be produced and transported using equipment specialized for “sour service,” treated and coated to withstand the corrosive effects of sour gas and is subject to stringent maintenance regimes. In some cases, very high levels of H2S contamination (10,000 ppm or greater) may require onsite gas treatment to reduce H2S to lower levels suitable for sour service handling. Otherwise, these assets cannot be produced.  

Traditionally, sour gas has been flared or combusted to transform the contaminated gas into less harmful substances. However, flaring sour gas produces other pollutants such as sulfur dioxide (SO₂), which contributes to acid rain; volatile organic compounds (VOCs); and nitrogen oxides (NOx), which can react with particulates and sunlight to form ozone. Additionally, incomplete combustion may release raw H2S into the atmosphere. 

Restrictions on flaring are increasingly stringent due to both regulatory mandates and voluntary industry efforts. For instance, the North Dakota Industrial Commission, which regulates the Oil and Gas industry in that state, requires operators to capture 90% of produced gas and reduce flaring. In New Mexico, the Oil Conservation Commission requires upstream and midstream operators to reduce routine natural gas flaring and venting by 98% by 2026.  

The U.S. Environmental Protection Agency has also recently revised its emissions regulations in NSPS OOOOb and EG OOOOc, aiming to phase out all non-emergency flaring in the future. 

Many operators have committed to voluntary emissions reduction programs. The Oil and Gas Methane Partnership 2.0 (OGMP 2.0) has emerged as an influential industry group who members include many large operators with producing assets in the United States and worldwide. OGMP 2.0 has developed a framework for estimating and reporting emissions from oil and gas operations, including emissions from tank venting, purging, and flaring.  

Gas Sweetening 

The process of treating sour natural gas to remove H2S so it can be sold instead of flared, generating emissions, is called “sweetening.”  

In our article, Gas Sweetening, Sour Gas Treatment Strategies by Volume, we identified the three primary categories of traditional gas treating methods for removing H₂S from produced gas, including (a) scavengers and adsorbents, (b) catalytic reactions, and (c) mechanical destruction or injection. These methods, however, have numerous downsides, including: 

  • Create negative downstream processing effects. 
  • Require the use of chemicals that can be expensive and present a safety risk. 
  • Require the disposal of contaminated media, creating environmental and safety risks. 
  • Operational complexity, requiring frequent oversight on location and problem solving. 

Valkyries Reduce Oil & Gas Emissions Using Next Generation Liquid Redox for H2S Treating 

The Liquid Redox (Reduction-Oxidation) process converts H₂S into elemental sulfur and water vapor byproducts using chemistry (Reduction) that can be regenerated and used again with exposure to air (Oxidation). 

Using a Next Generation Liquid Redox process, sour gas is directed into a treating vessel containing specialized chemistry and then exits the system sweet (without H₂S) into a gas sales line. The elemental sulfur byproduct is filtered out of the liquid, and the chemistry is then regenerated with exposure to oxygen. The regenerated chemistry is then recirculated back into the treating vessel to perform the reaction again.

H2S Treatment Technology That Keeps Your Dairy Digester to RNG Operation Green

Agricultural biogas streams are important feedstocks for upgrading to Renewable Natural Gas (RNG). Before biogas from a dairy digester or similar facility can be sold to a commercial pipeline as RNG, it must be treated for hydrogen sulfide (H2S) contamination. For a dairy digester biogas-to-RNG project to live up to its green value proposition, however, project designers have to consider not just the efficient aggregation of manure and capturing methane from the digester, but also the byproducts of the upgrading process itself.

Green H2S Treating Methods

There are several methods for treating H2S in dairy digester biogas-to-RNG applications, but only two are truly “green” from the standpoint of not creating negative byproducts: Biologic solutions and Next Generation Liquid Redox.

READ MORE: What Makes an H2S Treating Solution “Green”?

Biologic H2S Treating Systems

Biological processes are green because they utilize natural microorganisms to convert H2S into non-harmful compounds. However, this strength is also the primary weakness of biologic treating solutions. Living organisms are not as predictable or consistent as known chemical processes.

Downsides of biologic H2S treating options:

  • Because the bacteria colony in a biologic treater acclimates to the amount of H2S it consumes, biologics are highly sensitive to variations in gas flow rates, temperatures, and H2S concentrations, making the entire system more prone to unplanned downtime and lengthy restarts.
  • Usually require a complex and costly installation.
  • Typically require long initial start-up times to allow a critical mass of microorganisms to grow.
  • Often require additional equipment to maintain a steady state, increasing the cost of these systems and adding operational complexity.

Next Generation Liquid Redox (VALKYRIE®)

The next generation of liquid redox solutions, such as VALKYRIE Biogas-to-RNG technology, provide operators of dairy digester plants with a H2S purification solution that is not only green, but operationally robust. Like biological H2S treating options, VALKYRIE technology is a green solution, but unlike biologics delivers high reliability and fast startups.

Upsides to VALKYRIE technology:  

  • Reacts quickly to changes in gas flow, temperatures, and H2S concentrations for high reliability, process stability, and uptime.
  • Simple, cost effective “plug and play” installation
  • One-button, fast startup.

Additionally, VALKYRIE technology extracts elemental sulfur from the gas stream that can be sold as Simple Elemental Sulfur™ for use in organic food production, advancing the circular economy concept.
