COAL
expected to become a partner in the project and
to assist in plant construction and operation.
Feedstock coal for the plant will come from the
Uangjia Mine located near Longkou Harbor.
In full operation the plant, called China One,
would be expected to annually produce more
than 1 million tonnes of low-sulfur clean coal and
1.5 million barrels of oil.
SGI and MHI expect to complete the engineering
and economic feasibility work for China One in
the first half of 1995. A new venture, China Clean
Coal Refineries Ltd. (CCCR), is planned to carry
out LFC plant development activities in China.
CCCR would receive, for due consideration, an
exclusive territorial LFC technology license for
China.

BUGGENUM STARTUP DETAILED
At the 13th EPRI Conference on Gasification
Power Plants, held in October in San Francisco,
California a paper by H. de Winter and
W. Willeboer presented a review of the design,
construction and startup of Demkolec's 250megawatt
IGCC plant in Buggenum, The Nether
lands.
In 1989, the Dutch Electricity Generating Board,
N.V. Sep, announced plans for a 250 megawatt
Integrated Gasification Combined Cycle (IGCC)
demonstration plant. The plant was built and is
operated by Demkolec B.V., a fully owned
development partnership of N.V. Sep. The plant,
officially was
constructed at the existing power station site in
Buggenum, municipality of Haelen, and was
started up early 1994. The demonstration period
is defined as a 3-year period, after which the
named "Willem-Alexander Centrale,"
plant will be used as a commercial production
unit for the rest of its lifetime.
Project Description
The plant consists of the following main sections:

The project also comprises additional plant sec
tions for utilities, infrastructure, control systems
and power distribution. For the existing conven
tional power station at Buggenum only the coal
storage and handling facilities and cooling water
intake and outlet facilities could be used.
Total capital investment

required was
Proven technology was selected to the largest
possible extent. This applies, for instance, to the
gas turbine, steam turbine and waste heat boiler
unit, the air separation plant and the gas and
water treatment systems. Consequently, the net
efficiency of the plant, 43 percent, is not the
highest figure one can calculate today. On the
other hand, after demonstrating the integration
concept at this scale, further improvements by
new generation components can be
applying
achieved without fundamental uncertainties.
Environmental Aspects
The environmental aspects of the plant can be
summarized as follows:

desulfurization efficiency: better
