Off-gas processing | Amine regeneration
Sour refinery off-gasses contain large amounts of H2S, which can be harmful to human health and the environment if emitted in large amounts.
H2S in refinery recycle and off-gasses is removed from the process by absorption in amine absorbers. The rich amine loaded with H2S is regenerated in the amine regeneration unit by stripping off the acid gas.
The acid gas, primarily consisting of H2S and water vapor, is subsequently routed to sulfur recovery unit or a wet gas sulfuric acid unit (WSA) and the regenerated lean amine solution is recycled to the amine absorbers.
