Advancing R-GAS™ Entrained Flow Coal Gasification at Demonstration Plant in China

GTI and Yangquan Coal Industry Group, a Global Fortune 500 company, have established a joint development partnership for an Industrial Demonstration Project to demonstrate commercial readiness of the R-GAS™ gasification process in China. The installation will be located at the largest coal-to-chemicals plant in Shanxi Province. Construction is underway and commissioning is anticipated in 2019.

The project follows up successful long-duration testing of high ash-fusion temperature coal using GTI’s R-GAS gasifier technology at our pilot-scale facility in Des Plaines, IL. The R-GAS™ technology has been successfully operated at pilot-scale (18 tons per day) on sub-bituminous coal, bituminous coal, high ash fusion temperature anthracite coal, and petroleum coke—all with excellent test results.

The innovative technology is able to gasify the anthracitic coal predominant in China, which conventional gasification technologies have to date been unable to gasify due to its challenging properties. Testing validated the robustness of the R-GAS process, demonstrating the capability to achieve >99% carbon conversion even with this low-rank coal.

The gasifier footprint is about one-tenth the size of competing entrained flow technologies, and the compact size and advanced design features drive higher efficiency and lower cost. R-GAS consumes up to 30% less water and the higher efficiency results in lower overall emissions. The design enables rapid start-up and shut-down, feedstock flexibility—able to operate with all ranks of coal—and process optimization capability. It can be used for coal conversion to liquid fuels and chemicals, as well as power generation.

Capital expenditures are estimated to be 15–25% lower than the most economical entrained flow technology. The Yangquan industrial demonstration will validate long-duration reliability, operability, and capital costs.
