Title: Liquid phase methanation of high concentration CO synthesis gas

Abstract

Chem Systems Inc. believes that the Liquid Phase Methanation process can become an economic, reliable, and versatile method of converting synthesis gas mixtures to high-Btu gas. The process consists essentially of pumping an inert liquid upward through a reactor at a velocity sufficient to fluidize the catalyst and remove the reaction heat. A low-Btu gas is passed concurrently up the reactor where it is catalytically converted to a methane-rich gas stream. The exothermic reaction heat is absorbed mainly by the liquid as sensible heat and partly by vaporization. The overhead product gases are condensed to remove the product water and recover any vaporized liquid for recycle. The main liquid flow is circulated through a heat exchanger where the heat of reaction is recovered by generating high-pressure steam. To date, development of the process (under OCR-A.G.A. sponsorship for SNG production from coal) has completed the exploratory research and development stage and completed 90 percent of the construction and operation of a full-scale integrated pilot unit (PDU) and 40 percent of that of a full-scale integrated pilot plant. The pilot plant will incorporate a 2 x 15 ft reactor of the same basic design as the one used for the PDU andmore » bench-scale unit. The unit will be skid-mounted so that it can be moved to different plant locations for testing with synthesis gas from different coal gasification processes. At this time, the 2 most logical locations include IGT's HYGAS plant in Chicago and the CO/sub 2/ Acceptor plant in Rapid City, S.D.« less
