H2S Scavengers
We offer a proven, proprietary hydrogen sulfide (H2S) removal system that has been used successfully in hundreds of systems in the natural gas and petroleum industries. Our state-of-the-art technology is flexible enough to utilize at any point in the natural gas production and transmission cycle in order to ensure the efficient removal of corrosive, toxic H2S prior to sale. Field configurations are usually multiple or single vessel systems that are capable of operating without supervision. Such systems can be positioned anywhere in the production process, from the wellhead to the processing plant. Our systems ensure the removal of H2S from gas to below the standard 0.25-grain pipeline specification, regardless of how high the H2S levels in the raw gas may be at the outset.
Typical Field Installation Sites
- Central delivery point
- Single production well
- Offshore production site
- Gathering system
- Processing plant
- Primary system
- Backup system
- Polishing system
- Fuel gas treatment
The H2S scavenger system offers cost-effective removal of hydrogen sulfide. The operational expenses are also competitive when compared to other scavengers. These systems are specifically designed to be scaled up or down easily while remaining effective in large or small-scale applications. The chemical solution is selective for H2S; ensuring run time is not reduced by any other impurities within the gas stream.

H2S Removal Safety
The main concern in all projects that involve hydrogen sulfide is safety. The utilization of H2S scavengers converts lethal gas into a risk-free compound that can be easily disposed of in an environmentally safe method. Hydrogen sulfide batch treating will reduce facility operational expenses while eliminating potential risks related to H2S removal from gas.
Given the high operational costs and numerous technology choices, companies are often tasked with the difficult task of choosing an appropriate hydrogen sulfide scavenger and sulfur removal system. We can help in making this decision based on our widespread industry experience.
History of H2S Scavengers
H2S scavenger use in the natural gas industry has undergone extensive growth in the past few years, particularly in situations in which traditional amine treating is not cost-effective. Iron Sponge type processes were used on an extensive basis for many years in treating sour gas.
Increased environmental impact concerns’ regarding spent materials disposal, as well as labor costs related to replacement has resulted in the increase of scavengers with improved disposal properties.
Reservoirs with increasing amount of hydrogen sulfide comprised of part gas and oil are now being developed by gas operators. Hydrogen sulfide is a toxic gas that is actually denser than air. Furthermore, hydrogen sulfide is highly corrosive to surface and well equipment, can prove to be hazardous in tanks containing liquids, and must typically be used at a level of less than 4 ppm in order to meet sales specifications.
Only a minimum amount of equipment is required by hydrogen sulfide systems for gas treatment purposes in order to meet pipeline specifications. In many instances, two contractors will be arranged in a lead/lag or parallel flow arrangement. The lead/lag arrangement allows a scavenger to be used more efficiently while also adding flexibility to scavenger replacement scheduling.
