STATUS OF COAL PROJECTS (Underline denotes changes since June 1994)<br />

COMMERCIAL AND R&D PROJECTS (Continued)<br />

Texaco Syngas Inc. has initiated efforts to restructure the financing of the Texaco Cool Water Project and continues to negotiate<br />

with Southern California Edison Company for the power purchase agreement based on the California Energy Commission Com<br />

mittee Order dated November 2, 1992. Successful negotiation of the power purchase agreement, with necessary State of California<br />

approvals, would allow the acquisition of the Cool Water Gasification Facility, by Texaco Syngas Inc. from Southern California<br />

Edison Company, to be completed.<br />

Project Cost: $263 million for original Cool Water Coal Gasification Program<br />

$213.7 million for the commerical demonstration of the liquid-phase methanol process<br />

THERMOCHEM PULSE COMBUSTION DEMONSTRATION - ThermoChem,<br />

Energy (C-577)<br />

Inc., Northshore Mining, and U.S. Department of<br />

ThermoChem is implementing a Cooperative Agreement with the Department of Energy's Clean Coal Program for the demonstra<br />

tion of steam-reforming, low-rank coak at full scale (720 ton/day). This $37.3 million Cooperative Agreement will provide for the<br />

design, construction and two-year operation of a unit to produce char and synthesis gas for Northshore Mining's Direct Reduction<br />

Iron project in Silver Bay. Minnesota. ThermoChem is the prime contractor in this effort having won a DOE competitive award in<br />

1991. Stone & Webster Engineering and Ogden Environmental Services are subcontractors and partners in this effort. This<br />

demonstration project will supply the char for the first of three Direct Reduced Iron (DRI) units planned by Northshore Mining.<br />

An expansion of the ThermoChem unit would he expected to provide char for the two additional DRI units.<br />

The heat required for the gasification will be supplied by the combustion of cleaned gasification fuel gas in numerous pulsed com<br />

bustion tubes. The products of pulsed combustion are separated from the gasification products. Since no dilution of the<br />

byproducts of combustion or of gasified fuel gas occurs, a medium BTU content fuel (300-400 BTU/scf) gas will be produced. The<br />

turbulent nature of the pulsed combustor contributes to a high combustion heat release and density high heat transfer rates to the<br />

gasifier bed. The fluidized bed coal gasifier also offers high turbulence and heat transfer rates.<br />

In this project, design and permitting will be completed in 1996. with the operation beginning by the end of 1997.<br />

- TOM'S CREEK IGCC DEMONSTRATION PLANT TAMCO<br />

Power Partners and U.S. Department of Energy (C-580)<br />

TAMCO Power Partners, a partnership between Tampella Power Corporation and Coastal Power Production Company will build<br />

an integrated gasification combined cycle powerplant in Coeburn, Virginia. The U.S. Department of Energy will fund 48.3 percent<br />

of the $197 million project under Round 4 of its Clean Coal Technology Program.<br />

The project will demonstrate a single air blown fluidized bed gasifier, based on the U-GAS technology developed by the Institute of<br />

Gas Technology. The plant will burn 430 tons per day of local bituminous coal and produce a net 55 MWe. Power will be genera<br />

ted by firing low-BTU product gas in a gas turbine generator and by a steam turbine generator supplied by the waste heat from the<br />

gas turbine.<br />

A cooperative agreement was signed with the DOE in October 1992. A power sales agreement has yet to be signed.<br />

Project Cost: $196.6 million<br />

- UBE AMMONIA-FROM-COAL PLANT Ube<br />

Industries, Ltd. (C-590)<br />

Ube Industries, Ltd., of Tokyo completed the world's first large scale ammonia plant based on the Texaco coal gasification process<br />

(TCGP) in 1984. There are four complete trains of quench mode gasifiers in the plant. In normal operation three trains are used<br />

with one for stand-by. Ube began with a comparative study of available coal gasification processes in 1980. In October of that<br />

year, the Texaco process was selected. 1981 saw pilot tests run at Texaco's Montebello Research Laboratory, and a process design<br />

package was prepared in 1982. Detailed design started in early 1983, and site preparation in the middle of that year. Construction<br />

was completed in just over one year. The plant was commissioned in July 1984, and the first drop of liquid ammonia from coal was<br />

obtained in early August 1984. Those engineering and construction works and commissioning were executed by Ube's Plant En<br />

Division. Ube installed the new coal gasification process as an alternative "front<br />

end"<br />

gineering of the existing steam reforming<br />

process, retaining the original synthesis gas compression and ammonia synthesis facility. The plant thus has a wide range of<br />

flexibility in selection of raw material depending on any future energy shift. It can now produce ammonia from coals, naphtha and<br />

LPG as required.<br />

The 1,650 short tons per day gasification plant has operated using four kinds of coal-Canadian, Australian, Chinese, and South<br />

African, and about twenty kinds of petroleum coke.<br />

Over 43 million tons of feed including 1.6 million tons of petroleum coke, had been gasified by June 1994. The overall cost of am<br />

monia is said by Ube to be reduced by more than 20 percent by using coal gasification. Furthermore, the coal gasification plant is<br />

expected to be even more advantageous if the price difference between crude oil and coal increases.<br />
