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. WebAmino-Di-Ethylene-Glycol (ADEG®) also referred to as DIGLYCOLAMINE. ADEG is a primary amine used for total H2S and/or CO2 removal at low partial pressures. It works well at low pressures but requires the highest regeneration energy and has the highest corrosion risks out of all the alkanolamines. ADEG ® is also known as aminoethoxyethanol (AEE).
