Xinjiang Baicheng Longyu New Materials Co., Ltd.'s comprehensive utilization of coke oven tail gas to produce 200,000 tons/year ethylene glycol project author/source: Chemical Network Coal Chemical Industry Date: 2023-03-14 Click rate: 15 Xinjiang Baicheng Longyu New Materials Co., Ltd. was established on December 15, 2021. It is a joint venture established by Xinjiang Holding Investment Co., Ltd., a subsidiary of Henan Energy and Chemical Industry Group, and Baicheng County Urban and Rural Construction Investment and Development (Group) Co., Ltd., located in Baicheng County, Aksu Prefecture, Xinjiang Uygur Autonomous Region The new area of the industrial park is west of Jinhui Road and south of Tianshan gas filling station, covering an area of 142.5hm2 (equivalent to 2137.5 acres). It is planned to invest in a project with an annual output of 1.5 million tons of media coking supporting 200,000 tons of ethylene glycol and natural gas production of 200,000 tons of BDO (1,4-butanediol). The project relies on the abundant water resources and coal resources in Baicheng County and the opportunity of vigorously developing the coal chemical industry in the New Area of Baicheng County Industrial Park. At the same time, the construction of the project will realize the on-site transformation of Xinjiang's abundant coal resources, achieve the purpose of scientific and reasonable development and utilization, extend the comprehensive utilization of coal industry chain, and promote the optimization and upgrading of the coal industry structure. Xinjiang Baicheng Longyu New Materials Co., Ltd.'s comprehensive utilization of coke oven tail gas to produce 200,000 tons/year ethylene glycol project Construction nature: New construction unit: Xinjiang Baicheng Longyu New Materials Co., Ltd. Construction location: Baicheng Industrial Park New Area Construction scale: The coking scale of this project is an annual dry coke output of 1.5 million tons, and the ethylene glycol production capacity is 200,000 tons/year construction period : 24-month project investment: 457,515.84 million yuan Labor capacity: Project capacity 800 people Production system: 333 working days throughout the year Construction content: The project adopts the coal-to-ethylene glycol process and uses coking residual coke oven gas as the raw material for the production of ethylene glycol. It mainly builds a 1.5 million tons/year coking unit and a 200,000 tons/year ethylene glycol unit. In the selection of process technology solutions for this project, in line with the principle of utilizing local nearby coal resources and technical levels to strive for moderate advancement and deep utilization of resources, we chose to determine the coal preparation process and coking process technology based on the production of secondary metallurgical coke, and selected the process technology based on the production of industrial ethylene glycol. The coking scale of this project is an annual output of 1.5 million tons of dry coke, and the furnace type is YJL6780D.-|It is a side-loading coal tamping coke oven with dual downward injection, waste gas circulation, and carbonization chamber height of 6.78m. The furnace group size is 2×62 holes. It is equipped with coal preparation, screen coke storage, cold drum electric capture, ammonium sulfate (including residual ammonia evaporated helium), benzene elution, desulfurization and sulfur recovery, etc. The remaining gas is sent to coke oven gas to produce ethylene glycol. The ethylene glycol production capacity is 200,000 tons/year, including gas cabinets, coke oven gas initial pressure, TSA, supercharging, non-catalytic conversion, MDEA desulfurization and decarbonization, cryogenic separation, pressure swing adsorption and ethylene glycol units. It is equipped with corresponding public engineering facilities (including fresh water, circulating water, fire water, opening and closing stations, substations, refrigeration stations, air pressure nitrogen stations, etc.) and corresponding production and living auxiliary facilities (including central laboratories, foam stations, gas protection stations, mechanical and electrical instrument repairs, comprehensive warehouses, comprehensive office buildings, canteens, bathrooms and other living facilities). The fresh water, electricity and steam consumed by the project are provided by the adjacent BDO project. The sewage of this project is sent to the BDO project and is pre-treated and transported to the new district sewage treatment plant for centralized treatment.
