Compared with traditional chemicals, new materials such as PC, DMC, ABS, PBS, and PBAT have higher added value; at the same time, the implementation of the domestic “dual carbon” strategy, the transformation and upgrading of the manufacturing industry, and changes in the consumption structure will promote The rapid development of domestic renewable energy, new energy vehicles, 5G technology, consumer electronics, integrated circuits and other industries will inevitably lead to an increase in the demand for related new chemical materials.
Hengli Petrochemical, as a domestic private petrochemical giant, has followed the industrial chain from a piece of cloth to a drop of oil, from the market terminal to the front end of the industrial chain, realizing “crude oil-aromatics, olefins-PTA, ethylene glycol-polyester new materials” “The integrated operation and development pattern of the entire industry chain leads the high-quality development of the industry.
01. Rely on the existing “big chemical” platform to accelerate the layout of downstream high-end chemical new materials
After years of development, Hengli Petrochemical has now formed the basic development advantages of an upstream “big chemical” platform built on “refining + ethylene + coalification”. The company starts with a processing capacity of 20 million tons of crude oil and 5 million tons of raw coal. Output includes 4.5 million tons of PX, 1.2 million tons of pure benzene, 16.6 million tons of PTA (of which 5 million tons are under construction), 1.8 million tons of fiber-grade ethylene glycol, 850,000 tons of polypropylene, 720,000 tons of styrene, 400,000 tons of tons of high-density polyethylene, 140,000 tons of butadiene, 750,000 tons of methanol, 400,000 tons of acetic acid and 300,000 tons of pure hydrogen, and has transported and reserved various upstream raw material products that are in short supply in the country for the development of the downstream chemical new material industry chain. , possessing the rare ability to develop a world-class petrochemical platform.
At the same time, relying on the strategic support of the large chemical industry platform and years of accumulation in the new materials business, Hengli Petrochemical continues to make efforts in the field of new chemical materials business. On November 12, the official website of the Dalian Changxing Island Economic and Technological Development Zone government released a public participation announcement on the social stability risk analysis of Hengli Petrochemical (Dalian) New Materials Technology Co., Ltd.’s 1.6 million tons/year high-performance resin and new materials project. Hengli Petrochemical (Dalian) New Materials, a subsidiary of the company, plans to invest 20 billion yuan to build a 1.6 million tons/year high-performance resin and new materials project.
The construction content of the project includes a 450,000 tons/year ethylene oxide unit, a 200,000 tons/year ethanolamine unit, a 30,000 tons/year ethylene amine unit, a 420,000/260,000 tons/year phenol acetone unit, a 2*240,000 tons /year bisphenol A unit (using ion exchange method), 200,000 tons/year dimethyl carbonate unit, 260,000 tons/year polycarbonate unit, 2*200,000 tons/year CO2 refining unit, 130,000 tons/year Isopropyl alcohol plant, 300,000 tons/year ABS plant, 150,000 tons/year polystyrene plant, 80,000 tons/year polyformaldehyde plant, 72,000 tons/year PDO plant, 60,000 tons/year PTMEG plant, etc.
02. Plan for photovoltaic material grade polyester chips, and products will continue to develop towards high-end differentiation.
As a leading domestic polyester company, Hengli Petrochemical has always been at the forefront of the industry. While continuing to expand its production capacity, it is committed to the development of high-end differentiated products. On November 12, the official website of the Dalian Changxing Island Economic and Technological Development Zone government also released a public participation announcement on the social stability risk analysis of Hengli Petrochemical (Dalian) New Materials Technology Co., Ltd.’s annual output of 2.6 million tons of high-performance polyester project. The total investment of the project 4 billion yuan. The construction content mainly includes 2*600,000 tons/year industrial silk grade polyester slicing device, 600,000 tons/year film grade polyester slicing device, 300,000 tons/year film grade polyester slicing device, 300,000 tons /year ultra-bright polyester slicing device, 100,000 tons/year film grade masterbatch polyester slicing device, 100,000 tons/year photovoltaic material polyester slicing device, etc.
The construction of the project will effectively expand the production capacity and scale of the company’s polyester segment, and the layout of high-end polyester production capacity such as industrial silk grade and photovoltaic material grade will provide rapid development of high-end films such as downstream MLCC release base films, optical films, and photovoltaic films. Providing strong support for development, the company’s polyester industry will continue to develop towards high-end and differentiated development in the future, and its core competitiveness will continue to increase.
03. Continue to deploy degradable plastics and gradually improve the coverage of raw materials
At present, PBAT degradable plastics are a key development alternative field of environmentally friendly new material business. Hengli Petrochemical has the technical process and equipment capacity reserves of PBAT, and has the raw material supply capacity of PTA upstream of PBAT. Its subsidiary Kanghui Petrochemical has New PBAT production capacity of 33,000 tons has been put into operation. At the same time, Hengli Petrochemical has actively planned new related degradable plastics production capacity in accordance with the direction of national environmental protection policies and the market trend of degradable plastics, such as a 450,000-ton annual PBS biodegradable project that has started investment and construction.
According to Hengli Petrochemical’s announcement, while constructing a 450,000-ton PBS biodegradable project, it will also build supporting chemical projects, including a 350,000-ton/year ammonia synthesis unit, a 300,000-ton/year nitric acid unit, and a 300,000-ton/year ethylene diamine plant. Acid plant and 200,000 tons/year food grade CO2 plant. Adipic acid�For the company to produce degradable plastics. According to the input-output ratio of PBS/PBAT, 1 ton of PBS consumes 0.389 tons of adipic acid. 300,000 tons/year of adipic acid can supply the company’s PBS production capacity of about 771,200 tons, which can be fully covered. The company has put into production 66,000 tons of PBS/PBAT and will build 450,000 tons of PBS in the future.
