Zhundong 2.4 million tons medium-temperature coal tar deep processing project (Phase 1: 1.2 million tons)

Thread Content

This project is located in the Xiheshan Industrial Park, which is part of the eastern industrial cluster area in the Jundong Economic and Technological Development Zone in Xinjiang. The central coordinates of the project are 90°15′7.125″ east longitude and 44°33′46.546″ north latitude. The project is a new one that uses medium-temperature coal tar, tar residue, anthracene oil, and other materials as raw materials. It employs a constant-pressure distillation process with three connected towers; through processes such as pretreatment, distillation, blending, and drying, it produces 800,000 tons of distillate oil, 300,000 tons of carbon black oil, and 164,000 tons of coal powder per year. 200,000 tons of coal tar residue and 1 million tons of medium-temperature coal tar are processed annually. The total investment in the project is 700 million yuan, of which 8.235 million yuan is allocated to environmental protection measures, accounting for 1.2% of the total project investment. Main project: Construction of 4 distillation units (3 in use and 1 as backup), with a total processing capacity of 1.2 million tons per year. It mainly includes a loading/unloading area, tank areas, pre-treatment units, distillation towers, and drying units. Supporting facilities: construction of 4 21MW gas-fired heat transfer oil boilers (2 in use and 2 as backups), 2 10t/h gas-fired steam boilers (1 in use and 1 as backup), 4 5MW tubular heating furnaces (3 in use and 1 as backup), 1 cooling system with a capacity of 3000 m3/h for clean circulating water, 5 sets of coal dust cooling systems with a capacity of 500 m3/h for dirty circulating water, 1 soft water production system with a capacity of 10t/h, 3 air compressors with a capacity of 24.2 m3/min (2 in use and 1 as backup), and 5 nitrogen generators with a capacity of 270 m3/h. Environmental protection facilities: 10 low-nitrogen burners, 1 set of exhaust gas treatment equipment, 13 exhaust stacks (9 in use and 4 as backups), 2 sets of secondary activated carbon adsorption units, 1 hazardous waste storage facility with a capacity of 150 m2, and 1 sewage treatment plant with a processing capacity of 500 m3/day, etc. (Source: Environmental Protection Bureau of Jundong Economic and Technological Development Zone, Xinjiang)
