Cost Effective H2S Removal from Produced Water

In our recently released case study, we examined how Streamline’s ThunderOx™ sulfide elimination system dramatically reduced treatment costs at a high-H₂S produced water facility in Lea County, New Mexico—delivering more than $1 million per month in chemical savings while consistently reducing dissolved sulfides to below custody transfer limits.

In this blog post, we take a deeper look at the economics behind that result, exploring why conventional sulfide treatment programs often become prohibitively expensive and how selective redox chemistry can significantly lower the cost per barrel of produced water treated while improving reliability and safety.

Full Case Study

As operators push their asset development into areas prone to sour oil and gas resources in the Permian Basin, South Texas and elsewhere, they and the water midstream companies serving them, are faced with a growing challenge – produced water contaminated with elevated hydrogen sulfide (H₂S) and dissolved sulfides. In many areas, concentrations exceed 200 ppm, levels that create safety risks, corrosion, and costly non-compliance at saltwater disposal (SWD) and midstream transfer points.

For SWD facility engineers, the central question is: what is the most cost-effective way to consistently reduce dissolved H₂S to below 10 ppm?

The High Cost of “Conventional” Chemistry for H2S Removal

Traditional chemical treatment programs, often hemiformal based, are frequently applied in high volumes to combat elevated sulfide loads. In one Lea County, New Mexico case, an operator treating approximately 5,500 barrels per day of produced water containing ~200 ppm H₂S was spending approximately $1MM per month on chemical treatment alone.

Despite that high operating expense, the operator still struggled to:

  • Maintain dissolved H₂S below 10 ppm
  • Avoid midstream custody transfer surcharges
  • Prevent corrosion and vapor-phase H₂S exposure (>20,000 ppm headspace measured)

The result was escalating operating expense with inconsistent performance and an unsustainable scenario.

Selective Chemistry for H2S Removal = Lower Chemical Demand

Streamline’s ThunderOx™ sulfide elimination system changes the cost equation by selectively targeting sulfides via a liquid redox reaction rather than applying broad-spectrum oxidizers or non-selective scavengers.

Field performance data demonstrated:

  • Untreated H₂S (avg): 122–200 ppm
  • Treated H₂S (avg): 1.7 ppm
  • Custody transfer point: consistently <1 ppm
  • Reaction time: <5 minutes

Because ThunderOx selectively reacts with dissolved sulfide species, the required chemical loading is significantly lower than conventional scavengers. Less chemistry per barrel directly translates into lower cost per barrel treated.

Quantifiable Economic Impact of Streamline’s ThunderOx™ Sulfide Elimination System

In the Lea County application:

  • Volume treated: 5,500 BBL/D
  • Monthly chemical savings: Over $1 million
  • Manpower requirement: ~1 operator hour per day
  • Infrastructure additions: Minimal (peristaltic pumps + storage tank + SCADA integration)

Automation through SCADA-enabled dosing and remote tank monitoring further reduced labor costs and minimized overtreatment. For SWD facilities operating on thin margins, reducing both chemical costs and operator hours significantly reduces the total cost of ownership.

Beyond Chemistry Costs

The cost effectiveness of ThunderOx extends beyond reagent pricing:

  • Eliminates midstream surcharges and shut-in risk
  • Reduces corrosion-related maintenance and capital replacement
  • Improves HSE by eliminating lethal headspace H₂S levels
  • Converts H₂S to elemental sulfur with no special disposal requirements

We recommend when evaluating sulfide treatment programs, engineers should look beyond cost per gallon of chemical and focus on cost per barrel treated. In high-H₂S produced water systems, ThunderOx has demonstrated that selective chemistry, rapid kinetics, and automation can eliminate sulfide contamination at a fraction of traditional scavenger costs, while improving safety and operational reliability.

VALKYRIE® H2S Treating for Reducing Emissions in Oil and Gas Production – Debottlenecking Sour Crude Assets

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: 

  • 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. 

VALKYRIE® H2S Technology for Debottlenecking Sour Gas Production

VALKYRIE H2S treatment technology helps oil and gas operators overcome the constraint of limited sour takeaway capacity, unlocking the value of their sour oil and gas assets. Because VALKYRIE technology safely and effectively treats H2S without flaring or injecting acid gas, it facilitates the achievement of voluntary emissions reduction initiatives and regulatory compliance.

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.

VALKYRIE® H2S Treating for Reducing Emissions in Oil and Gas Production – Gas Lift Application 

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.

VALKYRIE® H2S Treating for Reducing Emissions in Oil and Gas Production

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).  

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

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. The regenerative nature of the chemistry reduces media changes, disposal costs and reduces chemical handling requirements on the well site.

VALKRYIE® H2S Treating System Environmental Sustainability Scorecard 2023

Streamline Innovation’s vision is Eliminating Emissions Through Technology.  We help industry around the world achieve environmental performance objectives, improve sustainability, and transition to a sustainable, lower-carbon future.

One of the benefits of using a Streamline Innovations VALKYRIE® H2S Treating System is the positive contribution to Environmental and Sustainability directives.  Unlike like some hydrogen sulfide treatment processes that create pollution or toxic wastes, Streamline’s VALKYRIE destroys H2S, and creates elemental sulfur that can be used for soil amendment in agriculture. 

Streamline’s VALKYRIE employs TALON®, a non-toxic, biodegradable Redox (“Reduction-Oxidation”) chemistry process that removes H2S from gas streams by converting it (“reduction”) to elemental sulfur and then regenerating the chemistry by introducing air (“oxidization”) so that the chemistry can repeat the treating process, over and over again.  The elemental sulfur is filtered from the chemistry and is accumulated in a container that will be used to store and transport the sulfur.

The VALKYRIE® H2S Treating System doesn’t just capture H2S, it destroys it, eliminating the need to flare sour gas, which is critical for reducing routine flaring and SO2 emissions.

The infographic below aggregates the environmental sustainability benefits delivered to our customers by VALKYRIE units operating during 2023.

ESG Scorecard - 2023 Streamline Innovations Environmental Sustainability Scorecard

Streamline Innovations Attending the Renewable Natural Gas Conference 2023

SAN ANTONIO, TX (December 6, 2023) – David Sisk, CEO, and Jacob Pratt, Senior Vice President of Sales with Streamline Innovations, Inc. (“Streamline”) will be attending the annual RNG Conference 2023 on December 11-14, 2023. The conference venue is the Waldorf Astoria Monarch Beach Resort & Club in Dana Point, California.

Interested parties are invited to contact Jacob Pratt to schedule a meeting to learn more about Streamline’s solutions for removing H2S from biogas produced from Anaerobic Digestion and Landfills.

Streamline’s proven biodegradable chemistry and processes convert toxic H2S into OMRI Certified elemental sulfur and water, which can be cleanly disposed of or used in agriculture as fertilizer. Many alternative treatment solutions result in hazardous or toxic byproducts that require special handling.  In addition, Streamline’s chemistry is regenerative, leaving a small environmental footprint and consuming much less raw materials than scavengers and adsorbent media, while handling changes in flow and concentration better than biological solutions.

VALKYRIE® Biogas-to-RNG Upgrading Technology – A Green Solution for Treating H2S

The VALKYRIE ECO Flex H2S treating solution is an expansion of the VALKYRIE ECO product line and utilizes Talon®, our non-toxic, biodegradable liquid redox chemistry for H2S treating in renewable natural gas (RNG) applications. The ECO Flex targets projects with higher gas volumes (1,000+ SCFM) such as landfill natural gas. The VALKYRIE ECO Flex can treat up to 3,300 SCFM and up to 14,500+ PPM H2S to a continuous outlet specification of less than 20 PPM of H2S.

The VALKYRIE ECO solution is designed specifically for H2S treating in RNG applications focusing on anaerobic digesters and landfills. The VALKYRIE ECO solution is highly effective in removing H2S from low pressure gas streams (-2 to 12 PSIG) with high and/or variable H2S concentrations.

Our VALKYRIE® H2S treating solutions use TALON® chemistry, a non-toxic and biodegradable Redox substance to remove H2S in an environmentally responsible way. The Simple Elemental Sulfur™ byproduct is approved by Organic Materials Review Institute (OMRI) for use in organic food production.
