At 16:25 on August 13th, upon the issuance of the command to add the necessary agents, the person in charge of the polypropylene unit at the Yan’an coal, oil, and gas resource utilization project immediately assigned personnel to carry out this task. With close cooperation from those working in areas such as process engineering, equipment, instrumentation, and electrical systems, by 18:45, the polymerization unit at Yan’an Energy and Chemicals’ olefin polymerization center was operating at full capacity, with a production rate of 27 tons per hour. Subsequently, the extrusion granulator and packaging stacking system were also successfully put into operation one after another. It is reported that the polypropylene plant is the main production facility in the comprehensive utilization project of coal, oil, and gas resources in Yan’an. This plant utilizes INNOVENE gas-phase polypropylene production technology from INEOS, a company based in the United States, and has an annual production capacity of 250,000 tons; it is capable of producing polypropylene products with various functions and for multiple applications. Construction began on September 11, 2015, and thanks to the diligent efforts of all the involved companies and workers over a period of more than two years, the installation was successfully completed by the end of 2017. Single-unit testing began in the first half of 2018, and on May 11, the extrusion granulator produced qualified polypropylene pellets ； The first trial run of the polymerization unit was successful on July 8th ； On August 13, the facility was able to produce qualified products throughout the entire process. The Yan’an coal, oil, and gas resources comprehensive utilization project is the largest energy and chemical project invested in by Yanchang Petroleum Group in Yan’an. With a total investment of around 24 billion yuan, the project consists of 10 production units along with the corresponding utility systems and auxiliary facilities. The project is located in the Luo River valley in the southern part of Fuxian County, Shaanxi Province. It uses associated gas from Yanchang Petroleum’s oil fields, refinery light oils, and coal as raw materials to build 10 sets of processing units, including ones for producing 1.8 million tons per year of methanol, 600,000 tons per year of methanol derivatives, 400,000 tons per year of light oil products, 450,000 tons per year of polyethylene, 250,000 tons per year of polypropylene, 200,000 tons per year of butanol, 80,000 tons per year of dipropyl heptanol, and 50,000 tons per year of EPDM rubber, along with supporting auxiliary facilities and off-site infrastructure.
