Recently, the ammonia synthesis tower, the core equipment of the Baling Hengyi Technological Transformation Project undertaken by Jiuhua Construction Zhongyuan Branch, was successfully hoisted at one time, and the project progress is progressing in an orderly manner
The construction site of Zhejiang Baling Hengyi 400,000 tons/year caprolactam capacity expansion project is located in Linjiang Industrial Park, Xiaoshan District, Hangzhou City, Zhejiang Province.
According to the plan, the project will be constructed in two phases.
The second phase of the project adopts the new cyclohexene method benzene hydrogenation process and the latest gas-phase rearrangement process technology of Sinopec, and builds a new cyclohexene method cyclohexanone production line, ammoximation cyclohexanone oxime production line, and gas-phase rearrangement caprolactam production line.
China's caprolactam production units are mainly concentrated in Fujian, Shandong, Zhejiang, Jiangsu and Shanxi provinces and cities, and the production technology is mainly HAO method and HPO method
The HPO method is a production process introduced by the Dutch company DSM, and it is also the production process adopted by the vast majority of domestic enterprises
Most of the caprolactam is used for the production of polyamide (PA6), and about 90% of the PA6 is used for the production of synthetic fibers.
