On January 15, the list of candidates shortlisted for the public tender for the design of the 4×100,000 NM3/HO2 air separation units, as well as the supply of complete sets of equipment and provision of technical services for Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project, was made public. First winning bidder: Hangzhou Oxygen Group Co., Ltd. The Shenhua Yulin Circular Economy Coal Comprehensive Utilization Project is one of the 102 key projects under the **14th Five-Year Plan**. It is led by China Shenhua Coal-to-Oil Chemical Co., Ltd., a subsidiary of the Energy Group, with construction and operation carried out by Guoneng Yulin Chemical Co., Ltd. The project is located in the northern part of the Qingshui Industrial Park within the Yushen Industrial Zone in Yulin City, Shaanxi Province. The total investment amounts to 79.836 billion yuan, of which 6.228 billion yuan is allocated to environmental protection measures. This project is designed as a model for the integrated utilization of coal in a clean and efficient manner, along with the production of high-end chemical products. Completion is scheduled for 2028, and upon completion it will enable the production of a variety of products such as coal-based specialty fuels, high-end polyolefins, and biodegradable materials. Project type: New construction. Project location: North Area of Qingshui Industrial Park, Yushen Industrial Zone, Yulin City, Shaanxi Province. Project components: This project covers key areas such as coal liquefaction, coal gasification, naphtha-methanol coupled cracking, MTO, polycarbonate production, and coal-based biodegradable materials; it includes a total of 38 process units, along with corresponding storage and transportation systems, utility facilities, and auxiliary equipment. Product portfolio: This project yields a wide range of products, including coal-based specialty fuels such as coal-based jet fuel and coal-based diesel, gasoline, coal liquefied asphalt, as well as coal-based biodegradable materials. It also produces fine chemicals such as xylene, mixed aromatics, and polycarbonates. It includes five main projects such as coal liquefaction, coal gasification, oil-alcohol co-processing and downstream processing, MTO and downstream processing, and coal-based biodegradable materials, along with the supporting utility facilities. The coal liquefaction section will see the addition of a new coal direct liquefaction production line with an capacity of 2.16 million tons per year, including a coal liquefaction unit with a capacity of 4.8 million tons per year (based on the amount of raw coking coal processed), a hydrogenation and stabilization unit with a capacity of 8 million tons per year (based on the amount of raw material processed), and a hydrogenation and upgrading unit with a capacity of 2 million tons per year (based on the amount of raw material processed). The coal gasification section maintains the original methanol production capacity of 2.1 million tons per year, while increasing the capacity of coal gasification and air separation in line with the hydrogen demand of the coal liquefaction section. It includes facilities such as 4x100,000 Nm3/h air separation units, 930,000 Nm3/h coal gasification units, shift conversion and acid gas removal systems, 400,000 Nm3/h hydrogen purification units, and a methanol synthesis plant with a capacity of 2.1 million tons per year. The MTO and downstream processing sections will be reduced by half based on the original MTO production capacity, with corresponding adjustments to the downstream production scale and product portfolio. This includes reducing the MTO plant’s capacity from 1.5 million tons per year to 750,000 tons per year, increasing the polypropylene plant’s capacity from 200,000 tons per year to 360,000 tons per year; adjusting the polyethylene plant’s output from low-density polyethylene (350,000 tons per year) to high-density polyethylene (340,000 tons per year). The production of ethylene oxide and propylene oxide derivatives in the downstream processing stage will be discontinued, while terpolymerized ethylene-propylene-diene rubber and ultra-high molecular weight polyethylene will see an increase in production. The oil alcohol co-refining and downstream processing sections have been upgraded with high-value-added processing units for naphtha derived from coal liquefaction, including units for the methanol-coupled cracking of naphtha at a capacity of 2 million tons per year. Coal-based biodegradable materials are partially added using methyl and n-butane by-products generated throughout the plant
