PKU Pioneer's steel gas utilization technology is an innovative technology that uses BFG, converter gas and coke oven gas from steel enterprises as raw materials to ultimately synthesize high-value-added methanol, ethanol, MEG and other basic chemical products through a series of purification and separation processes. Shanxi Woneng Chemical Co., Ltd., a subsidiary of Shanxi Jinnan Iron and Steel Group Co., Ltd. (formerly Shanxi Liheng Iron & Steel Co. Ltd.), reached strategic cooperation with Pioneer in 2018 on the PSA CO purification project from converter gas. The CO was later used as a raw material for ethylene glycol synthesis.

On August 21, 2020, the tail gas to 300,000 tons/year ethylene glycol and co-production of 156 million Nm3/year LNG project of Shanxi Woneng opened up the entire process and produced qualified ethylene glycol. It is currently the largest integrated tail gases to ethylene glycol project from coke oven gas and converter gas in China.

Shanxi Jinnan Iron and Steel Group Co., Ltd. made full use of the complementary advantages of converter gas with more carbon and less hydrogen, and coke oven gas inversely to produce high-value-added ethylene glycol products. While coke oven gas, which is rich in CH₄, is used to produce LNG through cryogenic technology. With a shorter production process and lower cost, the MEG manufactured by steel enterprises through steel-chemical complex production has a competitive advantage that is incomparable to that of other raw materials. The successful implementation of the project would set a precedent in the comprehensive utilization of converter gas and coke oven gas, which could reduce carbon emissions by 560,000 tons and nitrogen oxide emissions by more than 700 tons per year.
