STATUS OF COAL PROJECTS (Underline denotes changes since June 1994)
COMMERCIAL AND R&D PROJECTS (Continued)
For the project to build a 200 ton per entrained-flow day coal gasification combined cycle pilot plant, the electric utilities have
organized the "Engineering Research Association for Integrated Coal Gasification Combined Cycle Power Systems (IGC)"
with
10 major electric power companies and CRIEPI to carry out this project supported by MITI and NEDO.
Basic design and engineering of the pilot plant was started in 1986 and manufacturing and construction started in 1988 at the
Nakoso Coal Gasification Power Generation Pilot Plant site. Coal Gasification Tests began in June 1991 with the air blown
pressurized entrained-flow gasifier. Tests also began in 1991 for the hot gas clean-up system and a high temperature gas tur
bine of 1,260C combustor outlet temperature.
Project Cost: 53 billion yen
CTC CONTINUOUS MILD - GASIFICATION PROCESS Coal
Technology Corporation. U.S. Department of Energy (C-202)
CTC. under a cost-shared contract with the U.S. Department of Energy has developed the CTC/CLC process through
laboratory, batch, and 10 ton/day continuous pilot plant operations. The pilot plant operations, begun in 1991. were completed
in 1994. Tests indicate that the unique CTC system, using a wide variety of coal feedstocks, can meet the environmental
criteria of the U.S. Clean Air Act for 1995 and beyond bv using off-gases as heat for the reactors and can produce high quality
coke and char that meets all current quality specifications.
Construction of a commercial CTC/CLC plant is expected to begin in late 1995.

Syngas Inc., Star Enterprise, Delmarva Power & Light, Mission Energy (C-
Texaco Syngas Inc., Star Enterprise, a partnership between Texaco and Saudi Refining, Inc., Delmarva Power and Light Co.
and Mission Energy have begun joint engineering and environmental studies for an integrated gasification combined cycle
(IGCC) electrical generating facility. The project calls for the expansion of an powerplant existing adjacent to the Star En
terprise refinery in Delaware City, Delaware. The facility would convert over 2,000 tons per day of high sulfur petroleum coke,
a byproduct of the Star refinery, into clean, gaseous fuel to be used to produce about 200 MW of electrical power in both exist
ing and new power generating equipment.
Completion is planned for mid-1996. The project has the potential to reduce substantially overall emissions at the Delaware
more than double the current electric output and make use of the coke byproduct from the oil refinery. The
City facilities,
Phase I studies will require approximately one year to complete (in 1991) at an estimated cost of $6 million.
The existing powerplant would be upgraded and expanded and would continue to operate as a cogeneration facility.
Project Cost: $400 million
- DESTEC SYNGAS PROJECT Louisiana
Gasification Technology, Inc. a subsidiary of Destec Energy, Inc. (C-210)
The Destec Syngas Project, located in Plaquemine, Louisiana, began commercial operations in April, 1987, operating at rates
up to 105 percent of capacity. As of December 1994 the project has produced 42.1 trillion BTU of on-spec syngas and has
reached 3.369.1 14 tons of coal processed. It has operated for 37.817 hours on coal. A 90-day consecutive production record of
71.2 percent capacity was reached in October 1990. A 30-day consecutive production record of 99 percent availability and
89 percent capacity factor was reached in February 1992.
At full capacity, the plant consumes 2,400 tons of coal per day providing 30 billion BTU per day of medium BTU gas. The
process uses Dow-developed coal gasification technology to convert coal or lignite into medium BTU synthetic gas.
The process uses a pressurized, entrained flow, slagging, slurry-fed gasifier with a continuous slag removal system. Dow's
GAS/SPEC ST-1 acid gas removal system and Unocal's Selectox sulfur conversion unit are also used. Oxygen is supplied by
Air Products.
Construction of the plant was completed in 1987 by Dow Engineering Company. Each gasification module is sized to produce
syngas to power 150-200 megawatt combustion turbines. The project is owned and operated by Louisiana Gasification Tech
nology Incorporated, a wholly owned subsidiary of Houston-based Destec Energy, Inc., a subsidiary of The Dow Chemical
Company.
