Progress on the construction of the 5.5 million tons per year integrated industrial project for the clean, efficient, and comprehensive processing of low-grade coal at Xinjiang Yiwu Jiangna New Materials Company. Author/Source: Coal Tar Deep Processing and Hydrogenation Technology Collaboration Group. Date: April 20, 2022. Clicks: 13. At 12:30 on April 17, the pressure testing of two light oil pipelines in the No. 2 refined oil tank area for coal tar hydrogenation, as part of the aforementioned project carried out by China National Chemical Engineering Corporation No. 11 Construction Co., Ltd., was successful, marking the beginning of the pressure testing phase for the project’s process pipelines. Piping pressure testing is a crucial step at the construction site, as it allows for further verification of the safety, installation, and quality of the pipes. The project involves nearly 20,000 meters of process pipelines, with the largest diameter being 2200 mm and the thickest wall thickness at 30 mm. Among these, there are nearly 300 meters of pipes with a diameter exceeding 1 meter. The total number of welding joints is 365,000 inches, with 70,000 inches remaining to be completed – 80% of the work has already been finished. The project is divided into 280 pressure testing sections; 7 of these sections were tested on that day, with the maximum test pressure reaching 30 Mpa. At present, the pressure testing for the process pipeline packages of the Yiwu Jiangna coal tar hydrogenation project has been fully carried out, and all have passed the joint inspections by departments such as the quality supervision station, achieving success on the first attempt. All members of the project team will maintain high morale and strive toward achieving the “7.20 CCCC” goal. On April 8, China National Chemical Engineering 11th Construction Co., Ltd. and Yiwu Jiangna New Materials Co., Ltd. successfully signed a framework agreement for an integrated EPC+O solution covering the operation and maintenance of the 5.5 million tons per year coal upgrading pyrolysis project, as well as the development of green, high-value new materials through multi-energy complementarity. Project Overview: The integrated industrial project for the clean, efficient, and comprehensive processing of low-grade coal on a scale of 5.5 million tons per year by Xinjiang Yiwu Jiangna New Materials Co., Ltd. is being constructed in three phases. Phase 1 involves the construction of a new pyrolysis unit for upgrading low-grade coal with a capacity of 5 million tons per year, a clean coal production unit with a capacity of 1 million tons per year, a coal tar hydrogenation unit with a capacity of 500,000 tons per year (including a naphtha reforming unit with a capacity of 200,000 tons per year), as well as various utility facilities ； Phase 2 construction of a 200,000 tons/year green methanol plant using waste gas, a 100,000 tons/year formaldehyde dimethyl acetal plant, an LNG plant producing 80,000 tons/year as a by-product of waste gas purification, and utility facilities ； Phase 3: Construction of a 200,000 tons/year green ethylene glycol plant using waste gas, along with the associated utility systems. Leveraging the coal resources of Xinjiang Jianna Mining Co., Ltd., this project develops initiatives for the graded and differentiated utilization of low-grade coal in areas where such resources are abundant. The by-product gas generated during coal processing is used, through PSA technology, to extract CO, H2, and CO2 for the production of methanol and ethylene glycol with high added value. The coal tar produced as a by-product is subjected to full-range hydrogenation refining to yield high-quality petroleum products. The project is in line with **relevant industry policies, and it holds great significance for promoting coal development in the Hami region, facilitating resource conversion, exploring pathways for differentiated utilization, and driving local economic development. Company Overview: Yiwu Jiangna New Materials Co., Ltd. was established in 2018, jointly founded by Shandong Xingsheng Group, Lansi Heavy Equipment, Icelandic CRI, and Geely Company. Shandong Xingsheng Group was established in December 2001. It is mainly engaged in the exploration of ilmenite, the mining and processing of iron ore, as well as the sale of iron ore powder. It is the largest private iron ore producer in Shandong Province and the fifth-largest iron ore producer overall, with proven iron ore reserves that rank first in the province. Xinjiang Jianna Mining Co., Ltd. is a comprehensive manufacturing enterprise that specializes in the detection of copper-iron geochemical anomalies, coal mine exploration, coal mining, and coal sales. It has planned to build a coal mine with an annual production capacity of 5 million tons in the Hami region of Xinjiang (the first phase of this project, involving an open-pit mine with an annual capacity of 3 million tons, has already been approved), and it can supply raw materials for this project. Hami City in Xinjiang boasts large coal resource reserves, a variety of coal types, and easy mining conditions. Its coal is characterized by low sulfur, low phosphorus, low ash content, and high calorific value. The estimated resource volume is around 570 billion tons, making it the largest in Xinjiang, and it is suitable for establishing large-scale coal production and deep-processing facilities.
