Commissioning of Guizhou Qianxi’s coal-to-ethylene glycol project / Author/Source: Chemical Industry Network – Coal Chemicals / Date: May 29, 2018 / Clicks: 24. At 8:48 on May 25, 2018, the burner of the first gasification furnace in Qianxi Chemical’s 300,000-ton/year coal-to-ethylene glycol project was successfully ignited, producing qualified crude syngas; this marked the full commencement of the commissioning process for this ethylene glycol production facility. This gasification unit features the HT-L pressurized coal gasification technology, which was developed and designed by Aerospace Changzheng Chemical Engineering Co., Ltd. and holds independent intellectual property rights; it uses 3 φ2800/3200 type aerospace furnaces to produce syngas. The successful ignition of the gasifier has fully prepared the way for subsequent full-scale testing, and it also lays a solid foundation for the commissioning of the subsequent equipment. The 300,000 tons per year coal-based ethylene glycol production project in Qianxi was invested and constructed by Henan Energy and Chemical Group. The project began operations in the Qianxi County Economic Development Zone in March 2011, with a total planned investment of 5.436 billion yuan; it is one of the key coal chemical projects designated by Bijie City for development. Upon completion of the project, an annual production capacity of 300,000 tons of ethylene glycol will be achieved. In addition, it will also be possible to produce 41,200 tons of sulfuric acid, 432 tons of fore-run, 8,992 tons of fusel oil, 13,440 tons of light fractions, 6,048 tons of heavy fractions, 5,336 tons of DMO reconstituted fractions, and 17,576 tons of crude DMC per year. The project is overseen by Donghua Technology as the general contractor, with the main manufacturing process relying on the high-chemical CTEG syngas-based technology for producing ethylene glycol.
