Recently, the heating-up process for the 600,000-ton/year coal tar and low-carbon alkane recycling project operated by Ningxia Baowei New Energy Co., Ltd., which was constructed by the Second Engineering Company of Sinopec Fourth Construction Corporation, was completed successfully; the facility is now fully ready for commissioning and operation. The heating-up process for Ningxia Baoyao New Energy Co., Ltd.’s 600,000 tons per year coal tar and low-carbon alkane recycling project is a critical step in the construction of the heating furnace; the quality of this heating-up process directly affects the service life of the furnace as well as the stable operation of the entire unit. To ensure the smooth completion of the heating-up process for the 4 four-in-one furnaces and 4 reboilers, the project team from Petrochemical Fourth Construction Company’s Second Engineering Division carried out 84 hours of continuous work, successfully completing the task safely. Upon inspection and testing, the surfaces of all furnace walls were found to be dense and smooth, with no cracks, bulging, collapse, or peeling. The moisture content of the test samples was less than 2.5%, and the quality assessment resulted in an excellent rating; thus, the furnace drying process was a complete success. To date, the individual trial operations of nearly 20 compressors, over 60 air coolers, and more than 170 pumps that were under responsibility have all been completed. The calibration of electrical instruments has also been finished, 95% of the insulation work on equipment and pipelines has been completed, and the preparations for commissioning are now in the final stages. The Baoting coal tar and low-carbon alkanes recycling project commenced construction in June 2018. Through the joint efforts of all participating units, it took 18 months to successfully complete 37 individual projects, including coal tar hydrogenation, upgrading, and sulfur recovery, on January 2, 2020. The total investment for this project is estimated at 3.6 billion yuan; it will be developed in phases as part of a single planning scheme, covering an area of approximately 1,000 mu. Phase 1 of the project involves the construction of a coal tar hydrogenation unit with an annual capacity of 400,000 tons, a #1 refined coal tar modification unit with an annual capacity of 600,000 tons, a sulfur recovery unit with an annual capacity of 5,000 tons, a methanol cracking hydrogen production unit with a capacity of 2,000 standard cubic meters per hour, along with the necessary utility systems and auxiliary facilities. Phase 2 of the project entails the construction of a polymeric-grade propylene unit with an annual capacity of 300,000 tons, a polypropylene unit with the same capacity, a butane derivatives production unit with an annual capacity of 330,000 tons, as well as the required utility systems and auxiliary facilities. Construction is scheduled to begin in the first half of 2020, with completion and operation set for the first half of 2022. Ningxia Baowang New Energy Co., Ltd. was established in January 2016 with a registered capital of 400 million yuan. Aiming to make full use of the abundant coal and gas resources as well as the policy support available in the local area and its surroundings, the company invested in building a \"Coal Tar and Low-Carbon Alkanes Recycling Project\" within the New Materials Park of the Ningdong Energy and Chemical Industry Base, which is part of the \"Project No. 1\". This project uses medium- and low-temperature coal tar and low-carbon mixed alkanes as raw materials to produce chemical products such as benzenes, aromatics, and polypropylene. By recycling coal tar and low-carbon alkanes in an integrated manner, it not only increases the economic value of these products but also transforms waste into valuable resources, thereby promoting a circular economy and the expansion of the industrial chain.
