MHI, Southern Co. Complete Demonstration Phase of CCS Test

摘要

Mitsubishi Heavy Industries Ltd. (MHI) and Southern Co. have completed the initial demonstration phase of a carbon capture and storage (CCS) test at the Plant Barry power station in Mobile, Ala. The companies built a 25-MW carbon capture demonstration plant, consisting of a flue gas scrubber, flue gas carbon dioxide (CO_2) capture/regeneration system, CO_2 compression machinery, and electrical components, adjacent to the seven-unit James M. Barry Plant owned by Southern subsidiary Alabama Power (Figure 3). Notably, the facility employs the KM CDR Process, which uses a proprietary KS-1 high-performance solvent for C02 absorption and desorption that was jointly developed by MHI and Japanese utility Kansai Electric Power Co. and is said to use less energy than comparable systems.
