Dakota Gasification Company (Dakota Gas) owns and
operates the Great Plains Synfuels Plant near Beulah, North
Dakota. This is the only commercial-scale coal gasification
plant in the United States that manufactures natural gas. The
Great Plains facility began operations in 1984 and has been owned
and operated by Dakota Gas since 1988.
The plant uses the Lurgi
process to convert 6 million tons per year of lignite coal to
syngas and liquids. The average daily
production at Great Plains is about 160 million cubic feet of natural gas, the
majority of which is piped to Ventura, Iowa, for distribution in
the eastern United States. Many byproducts are also produced at
the plant, including: ammonium
sulfate, anhydrous ammonia, carbon dioxide, dephenolized
cresylic acid, krypton and xenon gases, liquid nitrogen, naptha,
phenol, and methanol. |
