Public Notice on the Environmental Impact Assessment for the 600,000-ton per year crude aromatic hydrocarbons hydrogenation technology optimization project in Hami, Xinjiang 2025-06-05 On May 9, 2025, the Environmental Impact Assessment and Emission Management Department of the Xinjiang Uygur Autonomous Region’s Department of Ecology and Environment issued a public notice regarding the acceptance of the environmental impact assessment application for the 600,000-ton per year crude aromatic hydrocarbons hydrogenation technology optimization project carried out by Xinjiang Xinhuixia Clean Energy Co., Ltd. The waste gas hydrogen production and coal tar hydrogenation projects of Xinjiang Xinhuixia Clean Energy Co., Ltd. (hereinafter referred to as “Xinhuixia Company”) were originally part of the second phase of Xinjiang Guanghui Coal Clean Processing and Refining Co., Ltd. (hereinafter referred to as “Clean Processing and Refining Company”)’s 10-million-ton-per-year project for the comprehensive processing and upgrading of coal ； Phase 1 consists of a 10 million tons per year dry distillation plant for lump coal and related supporting facilities, which is operated by Xinjiang Guanghui Coal Clean Processing Co., Ltd. Phase 2 includes a hydrogen production plant using 70,000 Nm3/h of raw gas, a 600,000 tons per year coal tar hydrogenation plant, as well as related supporting facilities; these are constructed and operated by Xinjiang Xinhuixia Clean Energy Co., Ltd. This project is a technical improvement and optimization initiative. Through adjustments to certain process parameters and the addition of a small number of equipment and pipelines using the existing facilities, this upgrade will enable the production of three new products – phenol oil, naphtha, and diesel – on top of the existing products. At the same time, the production volumes of 1# light coal tar, 2# light coal tar, and LPG will be reduced. The overall process flow consists of two parts: a hydrogen production process using 70,000 Nm3/h of raw gas, and a coal tar hydrogenation process with an annual capacity of 600,000 tons. The hydrogen production process using raw gas mainly includes a raw gas compression unit, a TSA pretreatment unit, a conversion unit, a hydrogen concentration unit, a hydrogen purification (PSA) unit, a desulfurization unit for the off-gas, and a high-precision hydrogen purification unit ； The coal tar hydrogenation process mainly includes a raw material pretreatment unit, a pre-hydrogenation and on-line refining unit, a hydrocracking unit, a distillation unit, a dry gas and liquefied gas desulfurization unit, and an acidic water stripping unit. Project Overview: Project Name: Optimization Project for 600,000-ton/year Hydrogenation Technology of Crude Aromatics at Xinjiang Xinhuixia Clean Energy Co., Ltd. Developer: Xinjiang Xinhuixia Clean Energy Co., Ltd. Project Nature: Technical renovation. Industry Category: This project falls under category C of the manufacturing sector as specified in the “National Economic Industry Classification” (GB/T4754-2017), specifically item 25 “Processing of petroleum, coal, and other fuels”, and further under sub-item 2519 “Other crude oil processing”. Construction location: This project is located in the existing project area of Xinjiang Xinhuixia Clean Energy Co., Ltd., within the Naomao Lake Coal Chemical Circular Economy Industrial Park of Yiwu Industrial Park. Land area: The technological upgrade project does not require any additional land; the total land area for the entire project is 26,800 m². Labor quota and operating hours: No additional labor quota will be established for this project. The annual production period is 333 days, amounting to approximately 8,000 hours, with a four-shift, three-shift operation system in place. Construction scale: The technical upgrade project involves adjusting the process parameters based on the existing facility, adding some equipment and pipelines; overall production scale and construction scope remain unchanged. After the technical upgrades, the overall scale of the project consists of a hydrogen production facility capable of producing 70,000 Nm3/h of raw gas, and a coal tar processing facility with an annual capacity of 600,000 tons. Production scale: This technical optimization does not change the production scale of the existing facilities; after the upgrades, the production scale of the project will be 70,000 Nm3/h for hydrogen production from raw gas, and 600,000 tons per year for the hydrogenation of crude aromatics (coal tar). Project construction content: The technical upgrade project makes use of the existing main equipment to optimize the coal tar hydrogenation unit, adding phenol oil, naphtha, and diesel products on top of the existing 1# light coal tar and 2# light coal tar products. The construction scope includes the main project, storage and transportation projects, auxiliary projects, and utility projects.

The clean and efficient utilization project for 15 million tons of coal at Xinjiang Hami HuiNeng Coal Clean and Efficient Utilization Co., Ltd., with a total investment of 8.58 billion yuan, has entered the equipment installation phase. https://bbs.hcbbs.com/thread-5695118-1-1.html (Source: Haichuan Chemical Industry Forum)
Xinjiang Xinhuixia Clean Energy Co., Ltd. was established jointly by Guanghui Refining & Chemical, Shandong Huidong, and Chongqing Yushanxia in the industrial park of Naomaohu Town, Yiwu County, Hami City. The overall project plan calls for the construction of a facility with an annual capacity of 1.6 million tons for the hydrogenation of crude aromatics; the first phase, involving a capacity of 600,000 tons per year for such hydrogenation, has been completed, with an investment of 1.5 billion yuan. The main business areas include the production and sales of phenol-based products, benzene and aromatic hydrocarbon products, light coal tar, white oil, tar pitch, residual oil, and liquefied gas. By leveraging Guanghui Energy’s high-quality coal resources rich in oil and gas, as well as Guanghui Refining’s abundant resources of crude aromatics, raw gas, and semi-coke, and by drawing on Shandong Huidong’s extensive experience and technology in the operation of crude aromatic hydrocarbon hydrogenation projects, it is possible to achieve maximum efficiency in resource utilization. Meanwhile, the rich investment and operation management experience of Yushanxia adds greater value to the company’s coal chemical products. Corporate philosophy: Integrity, pragmatism, innovation, and collaboration. The company advocates creating a vibrant work environment, humanized management practices, and a proactive attitude toward innovation, so that every employee can feel their own value at work, experience warmth within the team, and appreciate the charm of innovation in the processes involved.
