In the western area of the Ganhe Industrial Park within the Xining (**-level) Economic and Technological Development Zone, a large-scale chemical project covering an area of 299 hectares and requiring an investment of 12.77 billion yuan is under rapid construction. This is the olefin production project based on the comprehensive utilization of exhaust gases at the Qinghai Damei Ganhe Industrial Park, which began construction on March 23 this year. It is one of the six major projects with an investment of 5 billion yuan each that are being prioritized in Qinghai’s industrial sector this year. After two days of continuous rain, once the weather cleared, Xu Hao, a civil engineering engineer from Sinopec Ningbo Engineering Co., Ltd., who is in charge of building the workshop for processing powder resin particles in this project, along with over 30 workers, began pouring concrete on the third-floor platform early in the morning. As the weather grew cooler, 1,360 skilled workers from well-known domestic engineering companies in Ningbo, Shanghai, Zhengzhou and other places worked hard in 15 different locations to complete all the civil engineering work before the ground froze. Chemical engineering projects are characterized by flammability, explosiveness, and high risks; therefore, this project adopts the most advanced international models for design, procurement, and general construction management. Five key parties – the project owner, the general contractor, the supervision unit, the surveying unit, and the quality inspection unit – are responsible for managing and overseeing the project throughout its entire lifecycle ； Eight specialized supervision agencies in sectors such as electricity and petrochemicals leverage their respective strengths to provide supervision by area ； Two quality supervision agencies specializing in construction engineering and the petrochemical industry carry out “third-party” quality supervision. At the same time, a \"fourth party\" welding inspection agency is introduced to ensure the quality and safety of the project. As of the end of August, the project had received an investment of 3.207 billion yuan. As the construction of the project accelerates, nearly a thousand employees are undergoing intensive training, while the procurement of materials and the development of production systems are progressing in an orderly manner. All these careful preparations are aimed at ensuring the smooth operation of the project once it is completed. According to Zhu Ping, the executive deputy commander of the project construction command, as planned, this year is the \"civil engineering year\" for the project; by the end of this year, all civil engineering work related to the main production facilities will be essentially completed, and all underground construction tasks will be finished. Next year is the \"installation year\"; installation of machinery, electrical systems, instruments, and other equipment will begin in March next year, with an intermediate handover to be completed by the end of next year. Joint testing began in the first quarter of 2019, and qualified products were produced in the second quarter. Project acceptance is expected in September 2019, with commercial production set to begin in 2020. As the project investor and developer, Bai Yongqiang, chairman of Qinghai Damei Coal Industry Co., Ltd., explained that olefins are referred to by industry professionals as the \"mother of chemicals,\" and the products manufactured from olefins are widely used in various fields such as industry, agriculture, and healthcare. Therefore, the level of olefin production is often regarded as an indicator of a region’s industrial development level. The Ganhe Industrial Park is a **model park for circular transformation; Qinghai Guilu Chemical Co., Ltd. located in this park produces 900,000 tons of methanol per year, which is an excellent raw material for the production of olefins. In addition, the exhaust gases from various metallurgical enterprises in the park, combined with Qinghai’s abundant natural gas resources, complement each other in a circular manner, providing low-cost raw materials for the production of olefins through comprehensive utilization. It can be said that this project utilizes the world’s most advanced and mature environmental protection technologies, and is implemented in accordance with the requirements of cleanliness and zero emissions; it improves the efficiency of comprehensive resource utilization, making it an environmentally friendly olefin production project. It is for this reason that the advantages of the raw materials used in this project make the products highly competitive. Furthermore, each unit of this project is capable of producing products in hundreds of different grades, which can help alleviate the reliance on imports for such products. Among them, special chemicals such as polyethylene and polypropylene were previously dependent on imports; in recent years, domestic production has become available for these chemicals, but they remain in high demand. It is reported that the comprehensive utilization of exhaust gases from Damei Coal Industry for the production of olefins involves a capacity of 1.8 million tons per year of methanol-based olefins, 100,000 tons per year of olefins converted into propylene, 20,000 tons per year of MTBE and butene-1, 300,000 tons per year of polyethylene, and 400,000 tons per year of polypropylene. Once the project is completed and put into operation, the enterprise will be able to generate annual sales revenue of 6.53 billion yuan, with an average annual profit of around 1 billion yuan. More importantly, this project will fill the gap in domestically produced olefins in the province, thereby providing the necessary raw materials to support the development of a high-value-added new materials industry in Qinghai Province. At the same time, by connecting upstream and downstream processes to turn waste into resources, this represents a typical example of the close integration of industrial investment and the ecological environment in Qinghai Province.
