Abstract: Embodiments relate generally to methods and systems for processing a gas stream and for removing mercaptans from a feed stream. A method may comprise compressing a semi-treated gas stream, wherein the semi-treated gas stream comprises organic sulfur species and acid gas components; contacting the semi-treated gas stream with a lean solvent; removing at least a portion of the organic sulfur species and acid gas components from the semi-treated gas stream to produce a treated gas stream and a semi-rich solvent stream; contacting a feed gas stream with the semi-rich solvent, wherein the feed gas stream comprises organic sulfur species and acid gas components; and removing at least a portion of the organic sulfur species and acid gas components from the feed gas stream to produce the semi-treated gas stream based on contacting the semi-rich solvent with the feed gas stream.

Abstract: A system for processing a gas stream can include an acid gas removal unit comprising a first absorber unit, a compressor, and a second absorber unit. The first absorber unit is configured to receive a feed gas stream containing organic sulfur species and acid gas components, remove at least a portion of the organic sulfur species and acid gas components using a semi-rich solvent at a first pressure, produce a semi-treated gas stream, and produce a rich solvent stream. The compressor unit is configured to compress the semi-treated gas stream from the first pressure to a higher second pressure. The second absorber unit is configured to receive the compressed semi-treated gas stream, remove at least a portion of any organic sulfur species and acid gas components present in the compressed semi-treated gas stream using a lean solvent, produce the semi-rich solvent stream, and produce a treated gas stream.

Abstract: Embodiments include systems and methods for processing a feed gas and acid gas removal. A method may comprise receiving a feed gas to an absorber; contacting the feed gas counter-currently with a lean solvent stream to remove acid gas from the feed gas; producing a treated feed gas stream from the absorber; producing a rich solvent stream from the absorber comprising H2S and CO2 removed from the feed gas; receiving a side stream from the absorber to a side cooler; removing at least a portion of the heat of absorption from the side stream by the side cooler; producing a first output stream from the side cooler that is routed back into the absorber at a point below a draw point for the side stream; and producing a second output stream from the side cooler that is routed back into the absorber at a point below the first output stream.
