On July 10, 2021, good news came from Jiyuan Coal Chemical Technology Co., Ltd. in Eket Banner (hereinafter referred to as “Jiyuan Coal Chemical”). Its plant for producing 260,000 tons per year of ethylene glycol from coke oven exhaust gases began operations successfully, and polyester-grade ethylene glycol was produced with a purity of 99.94%; all specifications met the requirements of GB/T4649-2018 standards. The project utilizes the syngas-to-ethylene glycol technology provided by Shanghai Pujing Chemical Technology Co., Ltd. (hereinafter referred to as “Pujing Chemical”). The 260,000 tons per year ethylene glycol production project using coke oven gas at Jianyuan Coal Chemicals commenced operation of the esterification compressor on June 29, with preparations underway to start ethylene glycol synthesis ； At 22:49 on June 29, the system successfully supplied oxygen in a single operation; at 02:47 on June 30, qualified dimethyl oxalate was produced and sent to the hydrogenation unit, while at 06:41 the crude ethylene glycol product was sent to the distillation unit ； At 8:00 on July 8, the entire production process was operational, and polyester-grade ethylene glycol was produced; currently, the production capacity of each ethylene glycol plant is 95%, and the plants are operating stably. This facility is the sixth industrial-scale ethylene glycol project authorized by Pujing Chemical. Using coke oven exhaust as raw material, compared to ethylene glycol produced from coal, this method not only enables the resource utilization of the exhaust gas, is environmentally friendly, but also has lower costs, giving it strong market competitiveness. The ethylene glycol production project from coke oven exhaust gas at Ejin Horo Banner Jianyuan Coal Coking Co., Ltd., located in the Ejin Horo Economic Development Zone, utilizes the world’s first facility of its kind for converting coke oven exhaust gas into ethylene glycol. This facility enables the use of over 2.8 million tons of coke oven exhaust gas generated by the company’s coking plant for the production of ethylene glycol; once completed, it will become the largest production base for ethylene glycol derived from coke oven exhaust gas in the world. The 260,000 tons per year production of ethylene glycol from coker gas in Eket Banner Jianyuan Coal Coking Plant utilizes the syngas-to-ethylene glycol technology developed by Shanghai Pujing Chemical. Designed by Hualu Engineering Company, it is the world’s first plant for producing ethylene glycol from coke oven exhaust gases. The total investment in the project is 6 billion yuan, with construction starting in 2018. In October 2020, the air separation unit was put into operation.
