Pipeline-gas Demonstration Plant. Phase I: Demonstration Plant engineering and design. Volume 5. Plant Section 300: Gasification

Technical Report ·

OSTI ID:6307700

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. 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. This is Volume 5 of 24 which reports the design of Plant Section 300 - Gasification. In Plant Section 300, gasification of the coal feedstocks is achieved in the British Gas/Lurgi Slagging Gasifier. The gasifier operates at 450 psia, and the ash is removed as a molten slag. The coal is converted into crude synthesis gas by gasification with steam and oxygen in a counter-current moving-bed reactor. The crude synthesis gas is purified and converted into pipeline quality gas (SNG) in a sequence of downstream processing units (Plant Sections 400, 500, 600, and 800). Section 300 is a one-train unit with one operating gasifier and one spare. Each gasifier is designed to process 1256 tons per day of Ohio No. 9 coal and to produce 64 million standard cubic feet per day of crude synthesis gas. The crude gas from the gasifier is quenched in a scrubber to cool the gas and remove tar and particulate matter. It then passes through a waste heat boiler and four heat exchangers to cool the gas to 95/sup 0/F and to condense gas liquor and liquid hydrocarbons which are removed from the gas stream and subsequently recovered as by-products.
