CO2H2Sabsorption
CO2/H2S absorption refers to the removal of carbon dioxide (CO2) and hydrogen sulfide (H2S) from gas streams by contact with absorbent solvents, typically in countercurrent packed or tray towers. This process is widely used in natural gas processing, biogas cleanup, refinery gas treatment, and syngas purification to meet product specifications and protect downstream equipment.
The most common approaches employ chemical absorption with alkanolamine solvents such as monoethanolamine (MEA), diethanolamine (DEA),
In operation, the sour gas contacts the lean solvent in an absorber, where CO2 and H2S are
Applications aim to meet product specifications for CO2 and H2S concentrations, minimize corrosion and environmental impact,
