Approval application submitted for the upgrade project in Hami, Xinjiang. Author/Source: Huahua Net Coal Chemicals. Date: 2023-05-09. Clicks: 44. Xinjiang Tongshunyuan Energy Development Co., Ltd. is engaged in the processing and sales of lignite; its main product is semi-coke, while its by-products include coal tar, foam coal, and waste gas. The company’s project for the comprehensive utilization of lignite through pyrolysis for quality improvement, with an annual capacity of 1.8 million tons, was approved in January 2012. The first phase of this project, with an annual capacity of 1.2 million tons, required an investment of 192 million yuan. The main facilities of this phase were completed and put into operation in January 2013; it includes 12 internal-heating vertical carbonization furnaces, each with a designed production capacity of 100,000 tons per year. Additional facilities include coal preparation and storage systems, gas purification units, coal tar storage and transportation systems, as well as various auxiliary utilities. The second phase of the project, intended to increase the capacity to 600,000 tons per year through lignite pyrolysis for quality improvement, was not constructed. As the original project has been in operation for 10 years now, its production capacity has significantly declined; the capacity of each unit is only around 40,000 tons per year. This results in increased energy consumption, with the overall energy consumption far exceeding industry standards, which in turn raises the production costs of the enterprise and leads to poor economic efficiency. Therefore, it was decided to upgrade and renovate the original project at its current location. The upgrade and renovation project does not change the originally approved construction scale; therefore, the construction scale for this project is a lignite production facility with an annual capacity of 1.2 million tons. The main components of the construction include: a carbonization furnace area (comprising 10 type 3699 low-temperature dry distillation vertical carbonization furnaces and 10 air fans), along with associated gas purification equipment (including 10 primary cooling towers, 10 small cyclone collectors, 10 electrostatic tar collectors, 10 mist collectors, 10 gas fans, 10 return-flow cyclone collectors, and 2 liquid collection tanks); an ammonia water separation area (including 48 ammonia-water separation tanks, 4 oil collection tanks, and an ammonia water pump room); Tank Area No. 1 for coal tar (containing 4 coal tar storage tanks with a capacity of 4000 m3 each, as well as loading pump rooms and loading nozzles); Tank Area No. 2 for coal tar (containing 3 coal tar storage tanks with a capacity of 4000 m3 each); a raw coal crushing unit, raw coal silos, a raw coal screening unit, a slime coal silo, a lignite screening unit, Tank No. 1 for lignite, Tank No. 2 for lignite, Tank No. 3 for lignite; high and low voltage power distribution rooms, a control room, a nitrogen generation station, fire pump rooms and fire water tanks, a hazardous waste storage area, VOCs collection and treatment equipment, circulation water pump rooms and tanks, a cafeteria, and an 110 KV substation. After the project’s upgrade and renovation were completed, the 12 carbonization furnaces of the original project along with their associated equipment were removed simultaneously. The project has now obtained its registration certificate; project code: 2212-650522-0702-612363. Xinjiang Tongshunyuan Energy Development Co., Ltd.’s 1.8 million tons per year lignite pyrolysis upgrading and multi-product utilization project (Phase 1: 1.2 million tons per year) – carbonization furnace upgrade project. Contractor: Xinjiang Tongshunyuan Energy Development Co., Ltd. Nature of the project: technical renovation project. Location: Within the plant premises of Xinjiang Tongshunyuan Energy Development Co., Ltd., in the comprehensive energy industry zone of Yiwu Industrial Park. Land area: The project covers an area of 289,327.98 m2. Project investment: The total investment amounts to 350 million yuan, of which 304,374,000 yuan is allocated for construction costs and 40 million yuan for working capital. Scale of the project: This is a renovation project; the existing approved scale of production remains unchanged. The project involves building a facility capable of producing 1.2 million tons per year of semi-coke, with semi-coke being the main product, while by-products include coal tar, coal gas, and floc coal. The annual production of semi-coke is 1.2 million tons; the annual production of coal tar is 220,000 tons, and 2.1 billion Nm3 of gas is exported.
