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 which 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. Volume 6 reports the design of Plant Section 400 - Rectisol. The Rectisol Unit removes acid gases (H/sub 2/S, CO/sub 2/), naphtha, and other miscellaneous sulfur compounds from the cooled synthesis gas. The sulfur compounds must be removed from the synthesis gas because these compounds would deactivate the methanation catalyst in Plant Section 500. The removal of the acid gases and naphtha from the crude synthesis gas is accomplished by physical absorption in cold, circulating methanol. The impure methanol is hot regenerated to produce a single off-gas which is transferred to Plant Section 900 for sulfur recovery. The desulfurized synthesis gas is transferred to Plant Section 500 for shift and methanation. The Rectisol Process yields a purified synthesis gas which contains less than 0.2 parts per million of sulfur compounds. The design quantities of feed gas to Plant Section 400 and the major output streams from this section are as follows: crude synthesis gas feed - 64 million SCFD, purified synthesis gas - 60 million SCFD, acid gas stream - 2.9 million SCFD, and naphtha-22.2 tons per day.
