to the authors, the study confirmed the feasibility
of the scheme and indicated the cost advantages
of coproducing aromatic liquids. The overall
process thermal efficiency with the coproduction
was 80.5 percent.

RUSSIAN/CZECH COAL GASIFICATION
TECHNOLOGY LOOKING FOR A BUYER
A news item in Chemical Engineering states that
ZVU A.S. (Hradec Kralove, Czech Republic) has
been trying to find Western buyers for its coal
gasification technology. The 300-500 kilogram
per hour pilot plant was shut down for several
months, starting early last year. However, the
company had hoped to restart It sometime late
last year.
The plant was built with the assistance of
Russia's Ivtan Research Institute (Moscow) in
1989. Until there is a commercial demonstration
plant, there is thought to be little chance of sell
ing the technology in the West.

U.S./RUSSIA JOINT IGCC PROJECT
POSSIBLE
A report in Coal & Svnfuels Technology says that
the United States Environmental Protection
Agency, Battelle Corporation and United Tech
nologies Inc. are teaming up in a 7-year project
to help the Russian Academy of Sciences (RAS)
develop in Integrated Gasification Combined
Cycle (IGCC) plant. It was reported that the
group recently completed preliminary analyses
for the project, paving the way for a feasibility
study. A RAS spokesman was quoted as saying
construction on the Russian IGCC will almost
immediately begin after the feasibility study is
completed.

IGCC is being considered in Russia as a retrofit
option for the nation's aging, dirty, coal-fired
powerplants. IGCC Is attractive to Russian
power generators because of Its efficiency and
the potential to reduce SOx and NOx emissions
to 20 ppm. Current SOx and NOx levels from Rus
sian powerplants are 10 times that high.

LIGNITE GASIFICATION PROJECT PLANNED
FOR INDIA
According to a report In Chemical Engineering.
Oswal Agro Ltd. of India and Sasol of South
Africa are in the early stages of planning a joint-
venture lignite gasification project to produce syn
thetic natural gas, methanol and acetic acid.
Further announcements are expected this year.
The plant would be built in the Kutch region of
Gujarat State in India. Sasol would provide the
process technology

COAL GASIFICATION PROJECTS INCREASE
IN CHINA
Clean coal technology
projects continue to
proliferate in China (see Figure 1). Some recent
announcements include the following.
Shanxi Province
According
to China Daily air and water pollution
in the industrialized regions of Shanxi Province
will be lowered with construction of five new
projects involving heat generation and coal gas.
Using loans from international financial organiza
tions and governments, the province hopes to
reduce annual pollution of sulfur dioxide gases
by 21,000 tons and dust and smoke by
51,000 tons.
