Ten years of rapid development in chemical engineering technology – praising the prosperity and strength of modern China. This is just a starting point; more participation will make things even more interesting. With you here, HaiChuan becomes even better. [Ten years of progress in chemical engineering equipment] – continuous updates and summaries available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html. Enhance quality awareness and promote high-quality development. ----------------------------------------- On September 6, 2023, the 300,000 tons per year adipic acid production unit of the Hengli Petrochemical (Dalian) New Materials project, constructed by the Northeast Branch of Sinochem Second Construction Group Co., Ltd., began operations. The 300,000-ton/year adipic acid plant is one of the key process units in Hengli Petrochemical’s new materials-related chemical projects. Construction of this plant began on May 5, 2022; it utilizes an advanced water synthesis method from the patented technologies of China Tianchen Engineering Co., Ltd. to produce cyclohexanol, and uses dilute nitric acid as a raw material to manufacture high-quality adipic acid products. Hengli Petrochemical (Dalian)’s new material-related chemical projects include a 350,000-ton/year ammonia synthesis plant, a 300,000-ton/year nitric acid plant, a 300,000-ton/year adipic acid plant, and a 200,000-ton/year food-grade CO2 plant. Once the adipic acid plant comes online, the 300,000 tons per year of adipic acid produced there will be used to manufacture biodegradable plastics. This will cover the 66,000 tons of PBS/PBAT that Hengli Petrochemical already produces, as well as the 450,000 tons of PBS that will be produced in the future, thereby enabling self-sufficiency in these two raw materials and establishing a biodegradable plastic production base in the Dalian Changxing Island industrial park. Furthermore, once the 300,000 tons per year adipic acid production facility comes online, it will further enhance and complete Hengli Petrochemical’s entire industrial chain for biodegradable new materials, ranging from crude oil to PTA, and from adipic acid to PBAT. At the same time, adipic acid is also an important raw material for producing nylon 66; it enables the purification of carbon dioxide emissions with a concentration of over 95.0% from low-temperature methanol washing units to a food-grade level of 99.99%, thereby recovering industrial waste carbon dioxide and generating additional profits for the enterprise.
