Gas Sweetening

Gas sweetening is the process for the removal of mainly acid gases (H2S and CO2) and, in addition, the simultaneous removal of sulphur organic species (RSH, COS, CS2) from process gas. It is an essential step of sour gas processing for natural gas treatment, NGL recovery, LNGs, refineries and petrochemicals in order to meet transport and market specifications, to comply with environmental regulations for emissions and to control corrosion.
