Thread Content
Project Name: 1 million-ton coking transformation and upgrading project of Qujing Heijin Energy Co., Ltd.Location: Huashan Chemical Industrial Park, Qujing High-tech Industrial Development Zone
Constructor: Qujing Heijin Energy Co., Ltd.
Environmental Assessment Agency: Yunnan Boxi Environmental Impact Assessment Co., Ltd.
Project Overview: Located in the Huashan Chemical Industrial Park of Qujing High-tech Industrial Development Zone, the project covers an area of 20.2119 hm2. According to the project approval document and the Report, the nature of the project is renovation. It is planned to construct 2×55-chamber JT5550D type coke ovens along with associated production lines. The main construction elements include 2×55-chamber, 5.5-meter single-heating type rammed coke ovens, as well as 1×140t/h dry quenching equipment; in addition, facilities such as a coal preparation system, devices for dust removal and nitrogen oxide reduction from coke oven exhaust gases, and a chemical product recovery system will also be installed. Auxiliary facilities include refrigeration plants, demineralized water plants, air compression stations, laboratories, etc. Storage and transportation facilities comprise liquid loading/unloading areas, oil storage units, internal transportation roads, gas pipelines, etc. Utility systems include water supply and drainage systems, circulating water systems, office and living areas, etc. Environmental protection facilities include exhaust gas treatment systems, wastewater treatment systems, solid waste disposal and utilization systems, etc. The total investment in this project is 1.45 billion yuan; upon completion, it will produce 1 million tons of coke, 16,073 tons of ammonium sulfate, 13,712 tons of crude benzene, and 50,860 tons of tar per year.
