Amine regeneration flowsheet

Figure 4-1 is a process flowsheet showing how amine solution is circuĀ­lated to various refinery scrubbers to absorb H2S. The lean amine chemically combines with H2S (and unavoidably some C02) in the scrubbers. The resulting rich amine is stripped in the regenerator. Released acid gases (H2S and C02) are charged to the sulfur recovery plant. …
