Advancing R-GAS™ Entrained Flow Coal Gasification technology to lower costs and minimize environmental impacts in China

“Yangquan is one of the largest coal producers in China. The R-GAS™ gasification process offers a step-change improvement in efficiency and cost over current gasification technology and is uniquely capable of gasifying China’s low-rank coal.

Coal is a leading energy choice in China, and finding the most cost-effective and environmentally friendly ways of using it will help to maintain its role as a vital contributor to our economy.”

Mr. Zhai Hong, Chairman of Yangquan Group

GTI’s innovative R-GAS™ process is being demonstrated with Global Fortune 500 company Yangquan Coal Group at the largest coal-to-chemicals plant in Shanxi Province, China.

In 2019, construction was completed and commissioning is underway on the facility that will showcase breakthrough gasification technology to lower costs and minimize environmental impacts. The project is now in Phase 2, which will continue until 8,000 hours of cumulative operation have been successfully achieved.

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.

In support of this effort, GTI President and CEO, David Carroll and Michael Rutkowski, Senior Vice President, Research and Technology Development met with China Vice Premier Han Zheng and Shanxi Provincial government Vice Governor Wang Yixin and presented to energy ministers from around the world at the Taiyuan Energy Low Carbon (TELC) Development Forum in 2019.
