For this project, 2 billion yuan was planned to be invested in 2019; so far, 700 million yuan has been invested. The civil work is nearly complete, 80% of the pipeline installation has been finished, the equipment installation is almost complete, and 50% of the electrical and instrumentation work has been done. The 400,000-ton coal-to-ethylene glycol and 300,000-ton polyoxymethylenemethane circular economy demonstration project of Inner Mongolia Rongxin Chemical Co., Ltd. is located in the Sanyangliang Industrial Park in Dalat Banner, Inner Mongolia Autonomous Region. It represents a major project undertaken by the company to extend its industrial chain and promote the clean utilization of coal, building on its initial 900,000-ton coal-to-methanol project. The total investment in the project is 7.68 billion yuan, and construction began in August 2017. Zhang Yuzhen, deputy general manager of Yanzhou Coal Industry Ordos Energy Chemical Co., Ltd., said that the project is expected to complete the entire process and start trial operations in September 2019. Using coal as raw material and the four-nozzle gasification technology developed by East China University of Science and Technology, the project produces CO and H2 required for ethylene glycol production, as well as syngas needed for methanol synthesis; ethylene glycol is synthesized via an indirect method, while DMMn is synthesized indirectly from methanol. Among them, the ethylene glycol plant entered into EPC general contract agreements for the project with China Wuhuan Engineering Co., Ltd. and Huashuo Technology Co., Ltd.
