MAGSORB process for bulk separation of carbon dioxide. Progress report, November 27, 1991--February 27, 1992

摘要

Objective is to study the removal of CO(sub 2) from a fuel gas produced by a coal gasifier, with a K(sub 2)CO(sub 3)-modified MgO sorbent. During this period, the packed-bed reactor was completed. Three sorbent batches were prepared, six packed-bed tests were conducted, and thermobalance testing was completed. Betchel completed a cost estimate for the MAGSORB unit in a coal gasification/methanol synthesis plant. The use of MAGSORB offers three potential advantages over conventional processes: lower heat losses, simplified desulfurization, and potential integration with advanced hot gas desulfurization.
