Hydrogen Sulfide (H2S) Scavengers

Hydrogen Sulfide (H2S) Scavenger Solutions

Minimize H2S levels to increase worker safety and reduce odors

Hydrogen sulfide H2S?is a colorless, flammable, and toxic gas prevalent in the hydrocarbon processing industry. H2S scavengers are widely used in hydrocarbon processing facilities to maintain plant worker's safety and productivity and eliminate their odor emissions. These specialized chemicals react selectively with and remove H2S to help meet product and process specifications.

Veolia��s hydrogen sulfide scavenger's portfolio of products?is specially designed to be a cost-effective solution for a broad range of operating conditions and product compositions.

ProSweet hydrogen sulfide scavengers

ProSweet H₂S scavenger solutions include a variety of different products to address water-related odor problems arising from the release of hydrogen sulfide, mercaptans, ammonia, amines, volatile organics, and general nuisance odors.?

Control of hydrogen sulfide & reduce?sulfur compounds

For the control of odors due to reduced sulfur compounds such as H₂S and mercaptans, ProSweet H₂S scavenger solutions include 91��proprietary non-amine based organic sulfide scavengers and inhibitors. These products have been successfully applied in water or onto sludge phases to selectively scavenger and/or inhibit these odorants, consequently mitigating their release into eh air. They are non-toxic, non-corrosive and easy to apply liquid blends. Their application does not generate sludge or result in a system pH change.?

Veolia��s ProSweet hydrogen sulfide treatment and odor control products, used together with an in-depth system audit and engineering application and operational recommendations, will provide one or more of the following benefits:

Control of sulfides and nuisance odors
Improvement ambient air compliance to H2S and nuisance odor criteria
Elimination of unpleasant and unsafe work environment associated with hydrogen sulfide
Improvement of environmental image and public relations with surrounding communities
Maintenance of equipment integrity and prevention of corrosion-related maintenance costs due to H2S-influenced corrosion
Control of odors without creating additional sludge in systems being treated
Availability of technical and engineering support to provide operating and monitoring recommendations that complement chemical solutions for an overall cost-effective and robust solution

Case Studies

A Gulf Coast refiner was using metal salt technology in an ongoing program for asphalt treatment but continued to experience inconsistent results and unacceptable H₂S levels in asphalt s

FAQs

What causes hydrogen sulfide?: Hydrogen sulfide is produced because of the microbial breakdown of organic materials in the absence of oxygen. H₂S generation can occur in petroleum reservoirs, wastewater treatment plants, and sewers to name a few.
What are some of the hazards of H₂S?: H₂S is a colorless and deadly gas present in crude oil and many intermediate petroleum products. In recent years,?industry and public concerns have heightened awareness of health and safety issues associated with H₂S in petroleum products in refineries, terminals, shipping vehicles, and handling equipment. As a result, and in many cases, mandatory 10 ppm H₂S vapor space specifications have been added to these products. The specifications must be met prior to product shipment from the refineries and terminals to ensure the health?and safety of potentially impacted individuals.?
What are the sources of H₂S?: The direct introduction of hydrogen sulfide and other reduced sulfur compounds such as mercaptans generated from inorganic and organic reactions in petrochemical plants, paper mills, steel mills, and other industrial processes into process water and wastewater streams. In wastewater applications, a primary contributor to hydrogen sulfide is the biochemical reduction of inorganic sulfur compounds to sulfide by sulfate-reducing bacteria (SRB) under anaerobic or low dissolved oxygen conditions. The rate by which H₂S is generated depends upon the concentration of organics, sulfate, and dissolved oxygen in the water and environmental factors such as pH and temperature.
