The Hengli (Huizhou) PTA project, a key initiative of the Fortune 500 company Hengli Group with a total investment of 15 billion yuan and located in the Daya Bay Petrochemical Zone in Guangdong Province, is being advanced at full speed. It is understood that as of now, approximately 90% of the equipment procurement for the main plant area of the project has been completed, with equipment installation scheduled to begin next month. By the end of this year, most of the construction work will be completed and equipment installation will be largely finished; operation is expected to begin in the second quarter of next year. According to the relevant officials, at present, the key facility of this project—the PTA main plant area—has seen completion of tasks such as site grading, dynamic compaction, provision of temporary water and electricity supplies, construction of temporary roads, installation of construction fences, and geological surveys ； Pile construction is nearly complete ； The ceiling construction for PTA-1 and PTA-2 warehouses has been completed. Currently, the civil foundation work and underground construction are in progress. Nearly half of the procurement for surface pipeline installation materials has been completed, while 95% of the procurement for underground construction materials has been finished. On August 13, 2020, the investment cooperation agreement for Hengli Petrochemical (Huizhou) PTA project was officially signed, and construction commenced on January 7, 2021. The project includes two PTA production lines with a capacity of 2.5 million tons per year, the largest of their kind in the world, as well as auxiliary facilities such as wastewater treatment tanks. Once the project is completed and put into operation, the naphtha generated as a by-product of oil refining in the Daya Bay Petrochemical Zone in Guangdong Province can be converted on-site into upstream raw materials for the new materials industry. Chen Qi, general manager of Hengli Petrochemical (Huizhou) Co., Ltd., said that since moving into the Daya Bay Petrochemical Zone on August 19 last year, the care and support we have received from government departments at the provincial, municipal, and district levels have been truly unforgettable and touching. With the strong support and assistance of leaders at all levels and various departments, the project construction has also progressed smoothly. Data shows that the PTA industry serves as an important link between the two key sectors of the national economy: petrochemicals and chemical fiber textiles, occupying a core position that connects these sectors within the industrial chain. PTA reacts with petrochemical upstream products such as ethylene glycol to primarily produce polyester (PET). Polyesters can be processed into fibers, films, and plastic products, and are widely used in industries such as packaging, electronics, healthcare, construction, and the automotive sector. The Hengli Petrochemical (Huizhou) PTA project will build two PTA production lines with a capacity of 2.5 million tons per year each, the largest of their kind in the world. It will employ industry-leading green and intelligent production technologies, and upon completion it will be able to produce 5 million tons of PTA per year. Once this project is completed and put into operation, naphtha, which is a downstream refining raw material produced in the Daya Bay petrochemical complex, can be converted on-site into upstream raw materials for the new materials industry.
