Abstract

Processing schemes and arrangements for separating hydrogen sulfide, carbon dioxide and hydrogen from a fluid stream (112) including a solvent-based acid gas separation zone (113,114), a membrane separation zone (118,124) and a pressure swing adsorption unit (140) are provided. At least a portion of a carbon dioxide-lean non-permeate stream (128) produced in the membrane separation zone is recycled to the acid gas separation zone to strip and recover co-absorbed carbon dioxide from the solvent. Recovered carbon dioxide can be beneficially combusted in an associated gas turbine to generate electricity. Additionally, a portion of a pressure swing adsorption tail gas stream (144) and/or a sulfur recovery tail gas stream (156) may also be recycled to the acid gas separation zone for further processing.
