On February 10, the crude benzene separation unit of Jia Neng Yuan Group Ningxia Coal Industry Co., Ltd.’s 700,000 tons per year coal-to-olefins new material project resumed operations. **Ningxia Coal Industry Co., Ltd., part of **Energy Group, is a subsidiary under the control of **Energy Group. It is also the largest coal enterprise in the Ningxia Hui Autonomous Region, tasked with building coal production bases capable of producing hundreds of millions of tons of coal as well as modern coal chemical industry facilities. The registered capital of the enterprise is 21.11 billion yuan, of which **Energy Group holds 51%, while Ningxia State-owned Capital Operation Group Company holds 49%. The company’s main business areas are coal and coal-based oil and chemical products. In the coal sector, it operates 14 mining sites, both in operation and under construction, with a production capacity of 83.6 million tons ； In the coal-to-chemicals sector, 9 modern coal chemical projects have been built, including those for producing oil from coal, coal-based olefins, and coal-based methanol. These projects enable the production of 4.05 million tons of synthetic oils, 3.6 million tons of methanol, 2 million tons of polyolefins, 60,000 tons of polyoxymethylene, and 1 million tons of other chemical products. **The Olefins Division 1 of Ningxia Coal Industry Co., Ltd., which is part of the Energy Group, currently has two production units: one for coal-based olefins with an annual capacity of 500,000 tons (i.e., Olefins Unit 1), and another for methanol-based olefins with an annual capacity of 500,000 tons (i.e., Olefins Unit 2). The olefin plant is the world’s first commercially operational coal-based propylene industrial demonstration facility. The designed capacity is 1.67 million tons per year of the intermediate product methanol, and 500,000 tons per year of polypropylene. There were 184,700 tons of by-product gasoline components and 41,400 tons of liquefied gas. The project utilizes Siemens’ GSP gasification technology and Germany’s Lurgi MTP methanol-to-propylene technology. Construction began in 2007. It was completed and put into operation in August 2010. It entered commercial operation in 2012. The two olefin units employ Germany’s Lurgi MTP methanol-to-propylene technology and Ruhs polypropylene technology. Using methanol produced within the park as raw material, the designed capacity is to consume 1.67 million tons of methanol per year to produce 500,000 tons of polypropylene annually. There were 184,700 tons of by-product gasoline components and 41,400 tons of liquefied gas. Construction began in March 2011. Test run in August 2014. It entered commercial operation back then. **The two MTP units at the Olefins Division 1 of Ningxia Coal Industry Company, part of the Energy Group, suffer from high overall energy consumption, an unreasonable distribution of products, low yields of dienes, and an excessive amount of by-products. The company has carried out a project to upgrade the MTP process technology, with an investment of around 11.8 billion yuan. The existing MTP units were upgraded, two of these units were shut down, and the third-generation DMTO technology was adopted. A new MTO unit with a methanol processing capacity of 3.6 million tons per year was built, along with an EVA unit capable of producing 100,000 tons per year, an LDPE unit capable of producing 300,000 tons per year, and an HDPE unit also capable of producing 300,000 tons per year. The 700,000 tons per year coal-to-olefins new material project of Guoneng Ningxia Coal Industry is planned to be located in Area A of the coal chemical industry park within the chemical industrial base, on the open space to the north of the MTP renovation project. It is bordered by Jingwu Road (Guoning Road) to the east and Wanhua Avenue to the north, covering an area of approximately 90 hectares. The estimated total investment for this project is 16.25 billion yuan. Using coal as raw material, the project mainly includes process production units such as a gasification unit, a shift unit, a low-temperature methanol washing unit, a sulfur recovery unit, a methanol synthesis unit, a methanol-to-olefins unit, a vinyl acetate unit, an ultra-high molecular weight polyethylene unit, a full-density polyethylene unit, and an air separation unit ； Construct plant-wide facilities such as circulating water and fire pump stations, flares, acid and alkali stations, maintenance centers, off-site projects, and storage and transportation systems.
