新疆天业集团有限公司以电石炉尾气为原料,采用日本宇部兴产煤制乙二醇技术,于2011年7月在新疆石河子北工业区开工建设0.25 Mt/a煤制乙二醇一期年产0.05 Mt/a乙二醇和0.03 Mt/a 1,4-丁二醇项目,2013年1月建成了世界首套采用电石炉尾气制乙二醇工艺路线的生产装置,成功生产出优等品乙二醇。几个月来乙二醇装置一直满负荷运行,产品质量稳定,纯度99.9%以上,在220 nm时的紫外透
Xinjiang Tianye Group Co., Ltd. to calcium carbide furnace exhaust gas as raw material, the use of Japan’s Ube Industries ethylene glycol production technology, in July 2011 in Shihezi North Industrial Zone started construction of 0.25 Mt / a coal-based ethylene glycol a Producing 0.05 Mt / a ethylene glycol and 0.03 Mt / a 1,4-butanediol project. In January 2013, the world’s first production plant using ethylene carbide process from calcium carbide furnace tail gas was completed and the first class B Diol. Ethylene glycol unit has been running at full capacity for several months, the product quality is stable, the purity is above 99.9%, the UV transmittance at 220 nm
