Dga affinity with h2s and co2
WebMar 13, 2011 · INTRODUCTION ABSTRACT. Carbon dioxide (CO2), hydrogen sulphide (H2S) and oxygen (O2) gases dissolve in water condensate on carbon steel pipelines that react with the walls to form iron carbonate, iron sulphides, and iron oxides as the corrosion products, respectively. It is unknown whether these gases react individually or if there is … WebIn processing and treating both wellhead and refinery gases for H2S and CO2 removal, an unfortunate side effect is the loss of hydrocarbons and other light ends gases that are also soluble to varying degrees. Hydrocarbon solubility is never good news, unless the solvent is intentionally being used for dew point control.

WebDiglycolamine (DGA) Sulfinol® solvent Hydrogen sulfide (H 2S), carbon dioxide (CO 2), mercaptans, and other contaminants are often found in natural gas streams. H2S is a highly toxic gas that is corrosive to carbon steels. CO2 is also corrosive to equipment and … WebWhat is amine absorption process? Amine treating is a type of gas sweetening that refers to a group of processes that utilize solvents to remove acid gases, H2S (Hydrogen Sulfide) and CO2 (Carbon Dioxide), from process streams. It is commonly used in refineries and gas plants to improve safety, prevent corrosion and meet environmental regulations.
