Progress on the Construction of the 300,000-ton-per-year coal-based ethylene glycol production facility at Weihe Binzhou Chemicals. Author/Source: Huahua Network – Coal Chemicals. Date: July 26, 2020. Clicks: 124. As of now, the investment in the 300,000-ton-per-year coal-based ethylene glycol production project at Weihe Binzhou Chemicals in Shaanxi has reached 560 million yuan in 2020, with a total investment of 5.032 billion yuan to date. The office building, control building, and laboratory building in the area in front of the factory have been completed, with the office building already in use; the road network within the factory area as well as various underground pipelines have all been finished, and the air compressor station, startup boilers, and hydrogen production equipment have also been completed. The single-unit test of the raw water pump was carried out, the sewage treatment substation was connected to the power supply, and Boiler No. 1 was started up. The water transmission pipeline from the Hongyan River reservoir was adjusted so that water can be supplied normally; the transformers in the DMO substation have begun to be installed. The hoisting of the material handling equipment at the strip material yard was completed. The testing of the circulating water system, reclaimed water reuse system, and sewage treatment system was finished, along with the piping work for various chemical processing units; preparations are now underway for the purging of the pipelines with instrument air and factory air. Planning to carry out the chemical feeding trial run in October. The construction site for the 300,000 tons per year coal-based ethylene glycol production project of Shaanxi Weihe Binzhou Chemical Co., Ltd., which belongs to Shaanxi Coal Chemical Weihe Group, is located within the Xinmin Modern Coal Chemical Industrial Park in Bin County. The total investment in this project amounts to 5.495 billion yuan, and the project covers an area of 60,000 square meters. In April 2016, Shaanxi Weihe Binzhou Chemical Co., Ltd. signed a CTEG technology licensing agreement and an engineering design contract for a 30,000 tons per year coal-based ethylene glycol production project with Gaoxuehui and Donghua Engineering. The original owner of the project was Shaanxi Binchang Mining Group Co., Ltd. On November 19, 2014, the 300,000-ton coal-to-ethylene glycol project of Binchang Mining Group was officially transferred to Shaanxi Weihe Coal Chemical Group Co., Ltd. The project construction includes various process units such as coal-water slurry pressurized gasification, internal compression air separation, rectisolation via low-temperature methanol washing, low-temperature purification for carbon monoxide production, pressure swing adsorption for hydrogen production, hydroformylation to synthesize dimethyl oxalate, hydrogenation of dimethyl oxalate to produce ethylene glycol, and ethylene glycol purification. Additionally, it encompasses auxiliary facilities like a water system, thermal energy and power systems, an electrical power supply system, coal storage and transportation facilities, product tank farms, a plant front area, and off-site engineering works. Upon completion, the project will have an annual production capacity of 300,000 tons of ethylene glycol. The by-products generated include: 17,576 tons/year of crude DMC, 5,336 tons/year of heavy components from DMO, 5,920 tons/year of fusel oil, 13,440 tons/year of light fractions, 6,048 tons/year of heavy fractions of ethylene glycol, and 4,321.6 tons/year of sulfur.
