Adjustments to Bori’s 40,000-ton-per-year ultra-high molecular weight polyethylene project 2025-06-01 09:58·LeYi QiLuFeng On May 31, the adjustment plan for Bori’s 40,000-ton-per-year ultra-high molecular weight polyethylene project was made public. The project is being developed by Qingdao Chengzhi Huaqing Chemical New Materials Co., Ltd., and it is located at No. 66 Gangxing Avenue. The New Materials Industrial Park project (with an annual production capacity of 40,000 tons of ultra-high molecular weight polyethylene) has a total investment of 2,352.75 million yuan and covers an area of 528 mu. The construction of the main structures of this project is currently in progress, with operation expected to begin by the end of 2025. During the construction phase, changes in market conditions and the company’s overall strategic plans led to adjustments in the methods of raw material supply as well as the measures taken for dealing with organic waste gases. These changes in waste gas treatment methods resulted in an increase in the emissions of key pollutants. The changes include 1) the addition of pipeline construction. To ensure a sufficient and stable supply of ethylene raw material, ethylene is supplied through two methods: one involves installing a 30,000 m³ low-temperature ethylene storage tank to supply ethylene for production. 2 refers to the addition of a new ethylene pipeline with a length of approximately 700 meters, which runs from the boundary of Jinneng Plant through an utility tunnel into the Chengzhi Plant area to supply raw materials for production. Once the project is officially put into operation, ethylene can be sourced flexibly from either tank farms or pipelines; the type of ethylene used in both cases is the same, namely low-temperature liquid ethylene. During the project construction, the project owner revisited the process design; since the steam pressure in the park was not sufficient for production, a new steam pipeline was installed, with a length of approximately 750 meters. This pipeline runs from the Jineng plant boundary, through the existing pipe gallery, to the Chengzhi plant area, to supply heat for both production and domestic use. The amount of hydrogen used is small, and it is utilized intermittently; using dedicated pipelines for transportation would require constant pressure maintenance, which is not economically viable. Therefore, pipeline transportation of hydrogen is avoided, and steel gas cylinders are used for temporary storage in the plant area. 2) Change in steam source: Waste liquid is no longer incinerated, resulting in a lower overall calorific value and very little steam that can be generated; therefore, a waste heat boiler is no longer required. 3) Some changes in environmental protection projects: Due to strategic adjustments by the company, the progress of the POE project has been delayed. The amount of waste liquid generated by this project is low; considering economic costs, this waste liquid is disposed of externally as hazardous waste and is temporarily stored in a hazardous waste storage area. The waste liquid is no longer incinerated; organic waste gases are sent to an exhaust gas incineration unit for treatment, and the treated exhaust gases are released through a 35-m-high exhaust stack. To ensure safety and environmental protection, exhaust stacks have been added to the hazardous chemicals warehouse.

The Petroleum and Petrochemical Industrial Park in the Shangku High-Tech Zone of Korla, Bayingolin Mongol Autonomous Prefecture is located to the southwest of the Kurchu Horticultural Farm, 70 kilometers away from Korla city. The total planned area of the park is 100 square kilometers, with 9.88 square kilometers allocated for the initial development phase and 48 square kilometers for the first phase. The 1.2 million-ton PTA project of Sino-Thai Petrochemical, with a total investment of 5.62 billion yuan, has been put into operation ； The CNPC Tarim 600,000 tons/year ethane-to-ethylene project, with a total investment of 11 billion yuan, is about to be completed and put into operation ； The integrated petrochemical, refining, and textile production project of Tongkun Group and Zhongtai Group, with a total investment of 50 billion yuan, has been established in the park ； The 30-billion-yuan Wangjing Long PBAT project with a production capacity of 1.3 million tons has begun construction ； The groundbreaking ceremony for the bionic catalytic oxidation project of Anhui Zhuorun New Environmental Protection Materials Co., Ltd., with a total investment of 10.3 billion yuan, has been held. The projects established in the park effectively promote the integration, coordination, and simultaneous development of the petrochemical and textile-apparel industries. By leveraging technological innovation, they transform Xinjiang’s resource advantages into industrial and economic advantages, thereby fostering progress through science and technology. This approach also helps to create employment opportunities for people of all ethnic groups and contributes to the stable development of southern Xinjiang. The petrochemical park boasts advantages such as large development potential, sufficient safety distances, and strong environmental capacity. It is located outside the joint prevention and control area for air pollution control in Korla City, so there are no restrictions on flight or height construction; it is close to railways, roads, and oil and gas pipelines, requires no demolition, and thus has low construction costs. The wastewater treatment for the petrochemical park was designed by a renowned design institute in the field of industrial wastewater treatment in China; centralized treatment for large-scale industries was adopted to ensure that industrial wastewater is discharged in full compliance with regulatory standards. Leveraging its advantages, the park is accelerating its development. With building, strengthening, extending, and complementing industrial chains as its core strategies, it focuses on targeted investment promotion within these chains, making every effort to develop six major industrial clusters. By 2025, the park aims to attract investments of over 150 billion yuan, complete fixed-asset investments of over 100 billion yuan, achieve a total output value of over 100 billion yuan, and generate profits and taxes of over 10 billion yuan. It strives to turn Bayingolin Mongol Autonomous Prefecture into a pilot area for high-quality development in southern Xinjiang, thereby promoting the high-quality economic growth of the region.
