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. A report of the design effort is being issued in 24 volumes. This is Volume 7 which reports the design of Plant Section 500 - Shift/Methanation. The shift/methanation process is used to convert the purified synthesis gas from the Rectisol unit (Plant Section 400) into the desired high-Btu SNG product. This is accomplished in a series of fixed-bed adiabatic reactors. Water is added to the feed gas to the reactors to effect the requisite reactions. A nickel catalyst is used in the shift/methanation process, and the only reaction products are methane and carbon dioxide. The carbon dioxide is removed from the SNG in Plant Sectin 600 - CO/sub 2/ Removal. After carbon dioxide removal from the SNG, the SNG is returned to Plant Section 500 for final methanation. The product from the final methanation reactor is an SNG stream having a gross heating value of approximately 960 Btu per standard cubic foot. The shift/methanation unit at design conditions produces 19 Million SCFD of SNG from 60 Million SCFD of purified synthesis gas.
