Signing of Technical Contract for 1 Million Tonnes per Year Coal-to-Ethylene Glycol Project in Inner Mongolia / Author/Source: Huahua Network – Coal Chemicals / Date: 2018-06-01 / Clicks: 33. Recently, the signing ceremony for the technical contract related to the 1 million tonnes per year coal-to-ethylene glycol project carried out by Inner Mongolia Jiu Tai New Materials Co., Ltd. was held at Hualu Engineering Technology Co., Ltd. The project of Inner Mongolia Joutai New Materials Co., Ltd. to produce 1 million tons of ethylene glycol per year is located in the Tuoketuo Industrial Park in Hohhot’s Helinger New Area. In June 2017, the product scope of this project was changed; instead of producing 1.7 million tons of coal-based olefins and related fine products annually, it now focuses on the production of 1 million tons of ethylene glycol per year. The project uses coal as raw material, and produces syngas through the mature domestic aerospace powder gasification technology, while ethylene glycol is synthesized using Zongxin Wanfeng Davy Company’s formaldehyde hydroxymethylation technology. This signing marks Hualu Technology as the first engineering company in China to collaborate with Johnson Matthey and adopt its ethylene glycol technology. Mr. Wang Zhenzhen, Chairman of Inner Mongolia JiuTai New Materials Co., Ltd., Shan Xiuli, Chief Engineer of Hualu Technology, and Atul Shah from Johnson Matthey were among those present at the signing ceremony. The innovative coal-based ethylene glycol route uses coal as a raw material; syngas is produced through gasification, and then ethylene glycol is synthesized from it. The main process routes include the one-step synthesis method, methanol synthesis method, formaldehyde synthesis method, and oxalate hydrogenation synthesis method. In 2013, American Eastman and British Covestro’s Davy company jointly developed and mastered the industrial production technology for the hydrogenation synthesis of oxalates; the 1 million-ton per year ethylene glycol production project of Inner Mongolia Jutai Group was the first to adopt this technology. In September 2017, the 1 million-ton ethylene glycol project of Inner Mongolia JiuTai Group entered into a project engineering design contract with Hualu Technology. The content includes all process units other than the air separation unit, gasification unit, shift unit, and low-temperature methanol washing unit, as well as utility systems, auxiliary facility projects, and the overall project design work.
