Contract No. EF-77-C-01-2542 between Conoco Inc. and the US Department of Energy provides for the design, construction, and operation of a demonstration plant capable of processing bituminous caking coals into clean pipeline quality gas. The project is currently in the design phase (Phase I). This phase is scheduled to be completed in June 1981. One of the major efforts of Phase I is the completion of the process design and the project engineering design of the Demonstration Plant. This design effort has been completed. A report of the design effort is being issued in 24 volumes. This is Volume 8 which reports the design of Plant Section 600 - CO/sub 2/ removal. The CO/sub 2/ Removal unit removes carbon dioxide from the gas exiting the shift/methanation primary reactors (Plant Section 500). The removal of the carbon dioxide increases the gross heating value of the methanated gas from 404 to 880 Btu per standard cubic foot. The CO/sub 2/ free gas feeds the final methanator in Plant Section 500 which further upgrades the heating content of the SNG to pipeline quality standards. The carbon dioxide is removed from the methanated gas via absorption into a circulating solution of hot potassium carbonate. A Benfield process is employed for CO/sub 2/ removal. A portion of the CO/sub 2/ product from Plant Section 600 is used to pressurize the lock hoppers of the gasifier in Plant Section 300; the balance is vented to the atmosphere (26 million SCFC).
