Integration of cold solvent and acid gas removal |
| abstract |
A method for separating impurities from a natural gas stream is disclosed. The natural gas stream is cooled through heat exchange with one or more process streams to produce a cooled gas stream, wherein the cooled gas stream is contacted with a lean solvent stream in a contactor to separate hydrogen sulfide (H 2 S) from the cooled gas stream. and thereby producing a rich solvent stream and a partially treated gas stream. Carbon dioxide (CO 2 ) and H 2 S are separated from the partially treated gas stream in a membrane separation system to produce a fully treated gas stream and a permeate gas stream, the permeate gas stream mainly composed of H 2 S and CO 2 and , the fully treated gas stream consists mainly of natural gas. The fully treated gas stream and the permeate gas stream are at a lower temperature than the partially treated gas stream. The fully treated gas stream and the permeate gas stream include one or more process streams. |
