NDRC approves Fuxin coal gasification project

Datang Liaoning Coal-to-Gas Project delivers 4 bcm natural gas via pressurized gasification, plus tar, naphtha, sulfur byproducts, with a 334 km pipeline to Shenyang and branches, using methanation and low-temperature methanol purification.

China Datang Corporation's coal gasification project in the city of Fuxin, in the Liaoning province, received approval from the National Development and Reform Commission (NDRC), China Datang recently announced.

The project will have an annual production capacity of 4 billion cubic meters of gas through coal gasification, drawing on approaches seen with coke oven gas in power generation, as well as 509,000 metric tons of tar; 101,000 metric tons of naphtha; 58,000 metric tons of crude hydroxybenzene; 114,000 metric tons of sulfur; and 188,000 metric tons of ammonium sulfate in a year. Total investment in the project will be about $3.6 billion.

As a support facility to the project, a natural gas pipeline from the plant area to Shenyang, the capital city of Liaoning, amid recent NDRC coal plant approvals nationwide, together with branches from Shenyang to Benxi, Shenyang to Tieling, and Tieling to Fushun, totaling 334 kilometers in length, will be built.

The project will be built and operated by Datang Energy Resources Chemical Company Limited, amid ongoing coal gangue projects across China, a fully owned subsidiary of China Datang Corporation that was established for its energy and chemical businesses in June 2009.

As reported, the project will use processing technologies, including pressurized gasification, crude-gas cooling, low-temperature methanol purification, sulfur recovery, methanation, and wastewater comprehensive utilization. The scope of the project, comparable to recent large coal plant operations in China, is mainly comprised of 48 sets of pressurized fine-coal gasifiers, six low-temperature methanol purification devices, three sets of methanation devices, eight sets of 470-ton-per-hour high-pressure boilers, two 50-megawatt (MW) pump-condensing direct air-cooling generators and three 30-MW back-pressure units.

China Datang Corporation has signed supply agreements with urban gas companies in five cities in Liaoning, even as new nuclear plants move ahead nationwide. Land acquisition and site preparation are under way. Construction of the project is expected to officially begin in the second quarter of this year.
