The Shanghai Coking and Chemical Plant (SCCP) has chosen Texaco Development Corp.'s coal gasification process for an installation at Shanghai, China.
The plant will produce town gas and chemicals from coal, China's most abundant energy resource. SCCP, scheduled to start up 1994, is expected to significantly improve Shanghai's air and water quality, Texaco said.
SCCP is the largest supplier of town gas to Shanghai, but it meets only half the needs of the city. That forces residents to rely on direct coal burning for heating.
By gasifying 1,100 tons/day of coal, SCCP will be able to increase its production of town gas by 1.7 million cu m/day. And by eliminating the need to bum coal for heating and cooking, SCCP will improve air quality in the city, Texaco said.
The plant also will produce 200,000 metric tons/year of methanol.
The new SCCP gasifier will improve Shanghai water quality, Texaco said. Currently, large volumes of waste water are Discharged directly into the Huangpu River, a major water source for Shanghai. When the gasification plant becomes operational, this waste water will be mixed with coal to produce a slurry for the gasifier.
A water treatment unit will be installed to clean any water before it is discharged into the river.
The SCCP project is being developed in three phases, with the first two phases to produce town gas and chemicals and the third to include power generation.
The Texaco gasification process license agreement covers the project's first phase.
Once completed, this plant will bring to seven the number of Texaco licensed gasification plants in China producing fuel and chemicals for a variety of purposes.
The first Texaco gasification plant in China was licensed in 1978, Since then, four gasification plants have been built to produce ammonia and other chemicals from heavy oil.
Two other coal gasification plants are under construction.
The Lunan fertilizer plant in Shandong Province, scheduled to start up in mid-1992, will produce ammonia for fertilizer production. The Shougang coal gasification plant in Beijing will produce fuel gas for industrial use starting in 1994.
