Gasification Great Plains

The Lurgi process has been the most commercially accepted gasification method since its commercialization in 1936, and is used in the large plants in South Africa, in modified designs in Germany, and in the United States for the Great Plains faciUty (25,49,50). 

The system considered here is the Lurgi dry ash coal gasification process as used at SASOL in the Republic of South Africa and proposed for use at the Great Plains gasification project in North Dakota (2). The important steps in the process as far as...

One of the first commercial-size, coal gasification plants in the United States was the Great Plains Synfiiels plant that is operated by Dakota Gasification in Beulah, ND. This plant consumes over 5.5 million tonnes of coal per year and produces over 54 billion standard cubic feet (1.4 billion Nm3)of natural gas, 365,000 tonnes per year of ammonia, 24 million gallons of... 

The Great Plains Gasification Project—located in Beulah, ND, and now owned by Basin Electric, headquartered in Bismarck, ND—employs 14 Lurgi coal gasifiers in a 2.2 billion (1984 prices) project that has been in operation for nearly twenty years (Fig. 6-2). More advanced entrained-flow gasifiers dominate today s market, so this facility is not state of the art.

Capture of carbon dioxide from coal gasification is already achieved at low marginal cost in some plants. One (albeit where the high capital cost has been largely written off) is the Great Plains Synfuels Plant in North Dakota, where six million tons of lignite is gasified each year to produce clean synthetic natural gas. 

The Great Plains Synfuels Plant near Beulah, North Dakota, operated by the Dakota Gasification Company, provides strong impetus for the use of coal in the United States—the production of synthetic liquid fuel and gaseous fuels. The plant also produces carbon dioxide, which is captured and piped 200 miles north to Saskatchewan, Canada, where it is used for enhanced oil recovery (FOR) in the Weyburn Field. An additional amount of carbon dioxide is discharged to the atmosphere. The plant also produces anhydrous ammonia and ammonium sulfate for agricultural use, as well as a variety of other minor products.

Great Plains Gasification Associates (GPGA), a consortium of five companies with their own gas pipeline subsidiaries, originally owned the plant. The owner companies were American Natural Resources Company, MidCon Corporation, Pacific Lighting Corporation, Tenneco, Inc., and Transco Energy Company. American Natural Resources became the consortium s operating corporation.
