Public notice on the environmental impact assessment for the 2.4 million tons per year deep processing project of medium-temperature coal tar by Strait (Xinjiang) Energy Co., Ltd. in Zhundong
Thread Content
On January 9, the environmental impact assessment for Strait (Xinjiang) Energy Co., Ltd.’s project for the deep processing of 2.4 million tons per year of medium-temperature coal tar entered the stage of public announcement prior to submission for approval. The project is located in the Zhundong Economic and Technological Development Zone in Changji Prefecture; the first phase involves an investment of 700 million yuan, with a processing capacity of 1.2 million tons. Once all four phases are completed, this facility will consume 2.4 million tons of coal tar and tar residue each year, while producing 1.2 million tons of hydrogenated base oil – an output equivalent to that of a refinery with a capacity of one million tons, yet the raw materials come from by-products of coal chemical processing. Jundong is an important coal chemical industry base in China, and a large amount of medium-temperature coal tar and tar residue is generated during its production process each year. In the past, these materials were difficult to handle and posed high environmental risks. This project employs technologies such as three-tower series atmospheric distillation to deeply process \"waste\" materials like tar residue and anthracene oil, producing light fraction oils, carbon black oil, and coal powder. This not only ensures the harmless and resourceful treatment of hazardous waste, but also extends the coal chemical industry chain toward downstream areas with high added value, resulting in the production of high-quality base oils that are widely used in industries such as lubricants, cosmetics, and food packaging.
The project is to be constructed in four phases as planned, with 700 million yuan invested in each of phases 1 and 3 to focus on tar pretreatment and distillation； 2 billion and 4 billion yuan will be invested in phases two and four respectively, to focus on building hydrogenation facilities and improving product quality. This \"light startup, heavy upgrading\" approach not only controls initial risks but also leaves room for future product upgrades. Upon completion, it is expected to produce 800,000 tons of distillate oil, 300,000 tons of carbon black oil, and 164,000 tons of coal powder per year, resulting in substantial economic value. The proportion allocated to environmental protection measures was 1.05% (amounting to 7.315 million yuan); in modern chemical projects, the share of investment in environmental protection is usually higher. This figure may stem from the project’s inherent \"environmental benefits\" (waste utilization), but its specific environmental measures and long-term emission controls still require ongoing attention. At present, China still relies heavily on imports for high-end base oils. Through this initiative, Xinjiang takes advantage of its abundant locally available coal-based raw materials to create a closed-loop industrial chain that goes from coal to new chemical materials. This not only improves the efficiency of resource utilization but also explores a path for fine chemicals development with Xinjiang’s own characteristics as part of its energy strategy.
