WebDec 15, 2024 · 1. Introduction. Acid gases including H 2 S and CO 2, massively generated from coal gasification and natural processing, constitute a major hazard to human health and the environment [1], [2].H 2 S is extremely nocuous and corrosive, and it is also a major … WebApr 3, 2000 · Abstract. Effective removal of hydrogen sulfide (H 2 S) is one of the challenging problems associated with the production of natural gas. Since H 2 S is often present in natural gas along with varying levels of carbon dioxide (CO 2 ), selective …

WebThe simulation was first validated, and the parameters recorded errors below 5%. As the temperature increased from 35 °C to 70 °C, the molar flow of the CO2 and H2S in sweet gas also rose. WebKey findings from the work include our observation that the presence of H2O led to better H2S capture performances (i.e., capacity and H2S/CO2 selectivity). This is based on H2O led to a proton transfer mechanism during the H2S-amine interaction, giving rise to …
WebH2S – Hydrogen Sulfide. Amine treating plants remove CO2 (carbon dioxide) and H2S (hydrogen sulfide) from natural gas. Amine has a natural affinity for both CO2 and H2S allowing this to be a very efficient and effective removal process. Newpoint’s proprietary … Webreboiler duty.
