Optimizing U-GAS® applications

GTI’s patented U-GAS® is an advanced, single-stage, fluidized-bed gasification process. It operates at high efficiency with low emissions to produce low- to medium-Btu gas from various feedstocks, including all ranks of coal and coal/biomass blends. The synthesis gas can be used to produce power, chemicals, or fuel.

Synthesis Energy Systems, Inc. (SES) holds an exclusive global license for the U-GAS® coal gasification process. SES worked with GTI on the design of a U-GAS gasification plant in Zaozhuang City, China, to process waste coal. The Hai Hua $25 million syngas production plant began operation in early 2008. A $250 million integrated coal-to-methanol plant was constructed in Henan Province in China through a joint-venture agreement between SES and Yima Coal Industry Group Co., Ltd. The plant first produced methanol in late 2012.

The U-GAS technology has been licensed for use in the metals industry with seven units commissioned in 2015 and 2016, bringing the total number of installations to over a dozen units for chemicals and metallurgical processes in China.

Multiple coal gasification test campaigns for SES have been performed in GTI's pilot-scale gasification campus in Des Plaines, Illinois. GTI provides technical support to characterize the gasification properties of prospective fuels, conducts process simulations in support of new projects and applications, and assists in the design review of new U-GAS® plants for commercial projects.
