Progress on the 7.6-billion-yuan coal chemical project of Inner Mongolia Rongxin Chemical Industry Author/Source: Huahua Network – Coal Chemicals Date: 2018-04-25 Clicks: 53 Recently, various components of Inner Mongolia Rongxin Chemical Industry Co., Ltd.’s circular economy demonstration project, which aims to produce 400,000 tons of coal-based ethylene glycol and 300,000 tons of polyoxymethylenemethane per year, have been successfully commissioned, including the methanol production unit, the utility and auxiliary facilities, as well as the coal storage facilities. At 11:18 a.m. on April 11, the main substation for public and auxiliary facilities, constructed by China National Ninth Chemical Engineering Construction Corporation, commenced construction successfully. Sinochem Ninth Construction Co., Ltd. is responsible for the general contracting of the construction work related to the public utilities and auxiliary facilities of this project, including the #3, #4, and #5 circulating water systems, the desalination station, the main power substation for the entire plant, the civil engineering works for the second control room, as well as the installation of equipment in the #3, #4, and #5 circulating water stations, the desalination station, the water purification station, the reclaimed water reuse station, the sewage treatment station, the first central control room, the second control room, and the central laboratory. The contract value is 89.973 million yuan, with completion scheduled for February 10, 2019. At 9:18 a.m. on April 15, the construction of the 100-meter-diameter coal silo for the ethylene glycol and DMMn project at Inner Mongolia Rongxin Chemical, undertaken by China National Third Chemical Engineering Construction Company, officially commenced. At 10:18 on March 16, the commissioning ceremony for the methanol unit of Inner Mongolia Rongxin Chemical’s 400,000 tons per year ethylene glycol production project, which was constructed by 11th Chemical Construction Company, was held. 11th Construction Engineering Company was responsible for the civil work and installation of the methanol plant, the finished product storage area, and the plant’s flares; it also handled three other facilities, including the wastewater treatment plant and the reclaimed water reuse system. The total value of the contract was 157 million yuan ； The temporary construction facilities and office areas have been largely completed. The circular economy demonstration project of Inner Mongolia Rongxin Chemical Co., Ltd., with an annual production capacity of 400,000 tons of coal-based ethylene glycol and 300,000 tons of polydimethyl methoxymethane, is located in the Sanyangliang Industrial Park in Dalaat Banner, Ordos City, Inner Mongolia. Using coal as raw material, this project produces 400,000 tons of ethylene glycol and 300,000 tons of DMMn per year. It consists of various process units such as air separation units, gasification units, purification units, sulfur recovery units, methanol synthesis and distillation units, and ethylene glycol production units, along with supporting utility systems and auxiliary facilities. It is also integrated seamlessly with the various systems of the existing Rongxin Chemical methanol production facility. The Inner Mongolia Rongxin Chemicals project, with an annual production capacity of 400,000 tons of ethylene glycol and 300,000 tons of polydimethyl methoxide, uses coal as raw material and the four-nozzle gasification technology developed by East China University of Science and Technology to produce CO and H2 required for the manufacture of ethylene glycol, as well as syngas needed for methanol synthesis. Ethylene glycol is synthesized via an indirect method, while DMMn is produced indirectly from methanol. The EPC general contracting for the ethylene glycol plant was undertaken by Wuhuan Engineering, which utilized the WHB coal-based ethylene glycol technology jointly developed by China Wuhuan Engineering Co., Ltd., Huashuo Technology Co., Ltd., and Hebi BMW Group Industrial Co., Ltd. The total investment for the project is 7.68 billion yuan, with completion and operation scheduled for 2019. http://img.yf116.cn/image/img/20180425/854353207520.jpg
