The investment of more than 600 million yuan of 350,000 tons / year high-density polyethylene plant is currently the world's largest production equipment, the most advanced technology. The device introduces the technology of the ring pipe slurry method of Chevron-Phillips Company of the United States. It has the characteristics of large single-line production capacity and good product variety, and can produce blown plastic, film material, wire drawing material, pipe material and plastic injection. More than 20 grades of products such as cable materials. The commissioning of Maoming Petrochemical's 350,000 tons/year high-density polyethylene plant has filled the gap in Guangdong's plastic production varieties, which is conducive to optimizing the structure of ethylene varieties, improving the post-processing level of ethylene products, and promoting regional economic development.
350,000 tons/year high-density polyethylene is one of the 4 sets of new equipment for the expansion and expansion of Maoming's 1 million tons/year ethylene. It is also the project with the highest technical content, including 9 core equipments such as reactor circulation pump and catalyst activation furnace. With the introduction of the country, many process equipments have been adopted for the first time in China, and construction is extremely difficult. In order to ensure the high quality of the installation, the Maoming Petrochemical Engineering Project Management Department carefully organized and coordinated, and the engineering design, supervision, construction and other units concentrated more than 2,000 technical backbones to overcome difficulties, worked closely with foreign experts, and strictly followed the technical standards to install and debug. The installation of 135 imported equipment was completed at the end of May this year. The total amount of work was completed in only 17 months, and the high standard was achieved at the end of June this year.
The Maoming Petrochemical Chemical Division has prepared for the production from the perspective of large-scale technology and new features. In order to digest and absorb the advanced technology introduced as soon as possible, the division not only invites foreign experts to teach the technical points of the process, but also organizes employees to go to the counterparts of the same kind of equipment in the brother enterprises, and use the engineering construction quality inspection opportunities to familiarize themselves with the equipment and processes, and carry out the live-process competition. Anti-accident exercises and special technical lectures, etc., enable employees to quickly grasp the latest technology and operational essentials. At the same time, in order to ensure that the new devices are driving without fail, they are meticulous in promoting the processes of purging, airtightness, trial operation, etc. according to the start-up plan to ensure that the device has driving conditions. In the start of construction, the employees worked closely together, calmly responded, and strived for stability. In just 6 hours, the whole process was opened and a successful production was achieved.
Maoming Petrochemical's 1 million tons of ethylene expansion and expansion has opened a new chapter. After the production of the largest 300,000 tons/year polypropylene plant in China, on August 28, 350,000 tons/year of high-density polyethylene was put into operation, and the product quality was in line with national standards, achieving a safe and economical one-time success. Li Anxi, deputy secretary of the municipal party committee and manager of Maoming Petrochemical Company, expressed condolences and congratulations to the frontline workers at the installation site.
