Scrubbed gas leaving the gas cooling and scrubbing (Section 340) at a temperature of 236/sup 0/F is cooled to 110/sup 0/F. The raw gas leaving the scrubbed gas KO drum is compressed from 49 psig to 192 psig by a two stage centrifugal compressor. A raw gas compressor intercooler and an intercooler KO drum have been installed after the first stage compression in order to reduce the energy consumption for the compressor. Part of the condensate from the scrubbed gas KO drum is sent to gas cooling and scrubbing and the remaining condensate is combined for delivery to sour water stripping. The compressed raw gas from the overhead of the compressed gas KO drum reports to gas treating. The function of this section is the removal of almost all the sulfur compounds and some of the CO/sub 2/ from the raw gas. The removal of some of the CO/sub 2/ provides a means of controlling the product gas Btu value. The raw gas leaving the H/sub 2/S absorber KO drum enters H/sub 2/S absorber where cold lean Selexol solvent physically absorbs essentially all of the H/sub 2/S as well as most of the COS and some CO/sub 2/. The resulting product gas meets the required sulfur specifications. Absorber overhead gas after exchanging heat with the incoming raw gas and recycle gas in feed product exchanger and recycle product exchanger, passes to the CO/sub 2/ absorber for the removal of sufficient CO/sub 2/ to maintain a hhv of 300 Btu/scf in the IFG product. Solvent regeneration is described in detail.
