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, this project adheres to the principle of utilizing local nearby coal resources and technical levels to strive for moderate advancement and deep utilization of resources. It chooses to determine the coal preparation process and coking process technology based on the production of first- and second-level metallurgical coke, and selects 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. The furnace type is YJL6780D type, with double downward injection, exhaust gas circulation, and a side-mounted coal tamping coke oven with a carbonization chamber height of 6.78m. The furnace group size is 2×62 holes. It is equipped with coal preparation, screening coke storage, cold drum electric capture, ammonium sulfate (containing residual ammonia evaporated ammonia), benzene washout, desulfurization and sulfur recovery. 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. Equipped with corresponding public engineering facilities (including: Fresh water, circulating water, fire water, opening and closing stations, substations, refrigeration stations, air-pressure ammonia stations, etc.) and corresponding production and living auxiliary facilities (including central laboratory foam stations, gas protection stations, mechanical and electrical equipment 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 for pretreatment and then transported to the new district sewage treatment plant for centralized treatment.
