The **Energy Group Yulin Circular Economy Coal Comprehensive Utilization Project**, for which Tianchen Company is involved in its implementation! Author/Source: Coal Chemical Industry 114 Forum Date: 2021-09-22 Clicks: 5 On September 13, **** conducted an inspection tour in Yulin City, Shaanxi Province, and visited **Energy Group Yulin Chemical Co., Ltd. to learn about the comprehensive utilization of coal in a circular economy context. ****In his speech, he emphasized that the coal chemical industry holds great potential and a bright future; it is necessary to improve the comprehensive utilization of coal as a raw material for chemical production, promote the high-end, diversified, and low-carbon development of this industry, regard strengthening technological innovation as the most urgent task, and accelerate efforts to develop key core technologies. **The Circular Economy Coal Comprehensive Utilization Project of Energy Group Yulin Chemical Co., Ltd. **The Circular Economy Coal Comprehensive Utilization Project of Energy Group Yulin Chemical Co., Ltd. is located in the Qingshui Industrial Park in Yulin City. It is a key construction project in Shaanxi Province and for Energy Group. By utilizing the mature and reliable gasification process for methanol production, this project uses coal as raw material and, through processes such as gasification, CO conversion, low-temperature methanol washing, sulfur recovery, and methanol synthesis, creates a complete industrial chain that transforms coal into methanol, and further into polyolefins and various chemical products – essentially turning ‘black’ materials into ‘white’ ones. The gasification unit of Phase 1 of the Circular Economy Coal Comprehensive Utilization Project of **Energy Group Yulin Chemical Co., Ltd., which is under the general contracting of Tianchen Company, is one of the most critical components of this project. It utilizes GE’s water-coal slurry pressurized gasification technology; each single-nozzle gasifier is capable of processing 3,000 tons of coal per day, making it the largest of its kind in the world. The gasification and conversion systems within Tianchen Company’s scope of work use coal as the main raw material; through pressurized coal slurry gasification technology, crude gas composed primarily of CO and H2 is produced. After adjustment of the appropriate H/C ratio via conversion, this gas is sent to the purification units, where it is purified and separated to provide high-quality syngas for methanol and ethylene glycol production facilities. On December 26, 2020, the No. 2 gasifier of the project’s gasification unit (including the shift series) was successfully commissioned with its first feed, and qualified syngas was supplied to downstream processes on the same day ； On December 28, 2020, the entire process was successfully completed; it took 37 hours to produce qualified MTO-grade methanol, setting a record in China for the shortest time required from raw material input to methanol production.
