System and method for syngas treatment including integrated heat exchange

摘要

A system includes an acid gas removal (AGR) system 24 configured to remove an acid gas from an untreated syngas to generate a treated syngas, a hydrogen separation system 26 configured to receive the treated syngas to generate a non-permeate and a permeate, and an expander 84 configured to expand the non-permeate to generate a cooled non-permeate. The AGR system 24 includes a solvent chiller configured to cool a solvent via heat exchange with the cooled non-permeate.
