Deacidification processes
Natural Gas Treatment

Deacidification processes can be classified into three main families:

• scavengers or adsorption processes, which aim to remove H₂S or other minority sulfur compounds (COS, RSH, CS₂ , light sulfides), suitable for gases with low H₂S contents;

• redox processes, which aim to remove H₂S, suitable for gases with low to moderate H₂S concentrations, and which have the advantage of removing sulfur directly in solid form ;

• absorption processes, which remove CO₂ and H₂S, using chemical, physical or hybrid solvents, with specific features that make it possible to select the most suitable technology depending on the case to...
