What is an H2S scavenger?
An H2S Scavenger is a specialized chemical or additive widely used in hydrocarbon and chemical processing facilities. These specialized chemicals react selectively with and remove H2S to help meet product and process specifications.
Hydrogen sulfide (H2S) is a product of the thermal conversion of decayed organic matter. H2S is a toxic, flammable, and colorless gas and is a naturally occurring component of natural gas in some areas. Hydrogen sulfide is the predominant impurity in natural gas. Natural gas is classified as sour when H2S is present in amounts greater than 4 ppm. Sweetening natural gas is the process of removing hydrogen sulfide and is predominately done using a H2S Scavenger.
The ideal hydrogen sulfide scavenger initiates an instantaneous and irreversible reaction to remove H2S with no effect on oil, gas, or fuel quality. It helps reduce the potential for corrosion in equipment and pipelines maintaining asset integrity and reducing equipment maintenance and replacement cost. H2S scavengers play a vital role in guaranteeing gas specifications. The patented H2S Zero family of scavenger products increase the speed and efficiency of removal from Gas and NGL (Natural Gas Liquids). We are successfully treating at the well head and in mid stream and down stream applications working with producers, landfills, COS stream, Biogas applications, Renewable Gas and Liquid Hydrocarbons.
Industries we serve
H2SZero is an H2S scavenger manufacturer and exporter with a strong team of well-qualified engineers, we, H2, offer you an environmentally friendly and economical solution for hydrocarbon and chemical processing facilities.
Hydrogen sulfide (H2S) is a toxic, flammable, and colorless gas commonly present in the hydrocarbon processing industry. During oil and gas operations, Hydrogen Sulfide (H2S) can be a component of formation gasses dissolved in water and hydrocarbons. It is corrosive, extremely hazardous, and lethal at high concentrations. These hydrocarbon processing facilities use hydrogen sulfide scavengers to maintain plant workers’ safety, productivity and eliminate odor emissions.
