The ethylene glycol project at Shanxi Meijin Huasheng has been fully commissioned. According to Donghua Technology, on June 22, 2022, with the start of trial operations for the DMO synthesis unit series, the 300,000-ton/year ethylene glycol and LNG co-production project at Shanxi Meijin Huasheng, which was under the general contracting of Donghua Technology, was fully completed in terms of trial operations. The operational metrics of each device are excellent, and its energy consumption figures are far ahead of those in the industry. During the commissioning period, all process units operated at full capacity, ensuring that the project achieved full production levels and met all specified requirements. Within this period, the purification unit managed to convert coke oven gas into qualified LNG within 13 days, producing a total of 90,000 tons of LNG. The DMO synthesis system and EG synthesis system were commissioned, enabling production on the very day of startup. The ethylene glycol distillation unit had its process operationalized within 3 days, producing qualified polyester-grade ethylene glycol products on the first attempt. The distillation unit reduces steam energy consumption by 28% compared to units of the same type. To date, a total of 36,000 tons of ethylene glycol products have been produced, with 100% being of polyester grade. The Shanxi Meijin Huasheng Chemical Project is planned to produce 3.85 million tons of coking products, 300,000 tons of ethylene glycol, 155,000 tons of LNG, and 60,000 tons of sulfuric acid per year. Phase 1 will involve the production of 2,000 m3/h of industrially pure hydrogen, while Phase 2 will enable the production of 10,000 m3/h of such hydrogen. Among them, LNG and high-purity hydrogen achieved full capacity operation in November 2021. On March 28, 2022, polyester-grade ethylene glycol was produced.
