Market Status And Prospects Of Caprolactam (CPL) Products

Caprolactam (CPL) is an important monomer for the production of nylon 6 fiber (Jin Guan) and nylon -6 engineering plastics. It has excellent thermal stability, processability, mechanical properties and chemical resistance. Globally, the main consumption areas of caprolactam are fiber (civilian silk, industrial yarn, carpet silk), engineering plastics and food packaging film. It is widely used in automobiles, ships, medical products, daily necessities, electronics and electrical fields. Caprolactam can also be used in the production of antiplatelet drug 6-- amino hexanoate, producing laurazone and so on. It has a wide range of uses.

The technology of domestic caprolactam built before 1990s was backward, with high production cost and high environmental pressure. Now only Zhejiang polyamide company nylon plant is still in production, the rest of the devices have been shut down. At the beginning of 1990s, Nanjing DSM Chemical Co., Ltd. and Sinopec Yueyang Baling Petrochemical Company introduced the 50 thousand tons / year caprolactam production plant from HPO, respectively, from Holland. Sinopec Shijiazhuang chemical fiber Limited liability company introduced SNIA company toluene method to produce caprolactam technology, and built a 50 thousand ton / year device.

In recent years, domestic advanced technology has been imported continuously to transform the existing equipment, and the capacity and quality have been promoted rapidly. Nanjing DSM Chemical Co., Ltd. production capacity of caprolactam increased from 50 thousand tons per year to 200 thousand tons / year. Sinopec Baling Petrochemical Company has increased its capacity from 50 thousand tons per year to 200 thousand tons / year through technological research and development. Sinopec Shijiazhuang Chemical Fiber Co., Ltd. adopted the production technology of toluene in Italy SNIA company. In 1999, a set of caprolactam production equipment with a production capacity of 50 thousand tons / year was built. In 2002, it was cooperated with Sinopec in the development and application of amorphous nickel as a promoter. The hydrogenation reaction system of benzoic acid partially replaced the Pd/C catalyst and the hydrotreating technology of substituted lactams instead of Potassium Permanganate. The capacity of the plant expanded to 160 thousand tons / year in 2008.

It is estimated that the production capacity of caprolactam will be 970 thousand tons in 2014, including Baling Petrochemical and Nanjing DSM, which will plan to add 200 thousand tons / year equipment. Jiangsu group is planning to build a new 100 thousand ton / year production facility in Yangzi chemical industry park. Sinopec Shijiazhuang chemical fiber Limited Liability Company plans to build 120 thousand tons / year production facility. In addition, DuPont and BASF will jointly set up a 150 thousand ton / caprolactam production facility in Hainan in 2010.

In recent years, the production capacity of caprolactam in China has been increasing, and the output has also increased. However, it still can not meet the rapid development of downstream industries. The production gap of caprolactam in China is mainly dependent on imports. The annual import volume accounts for over 60% of total consumption and high dependence on imports. Therefore, research and development of domestic caprolactam production technology is conducive to improving domestic competitiveness in this industry. Upstream and downstream of Caprolactam industry Technological progress and healthy development play a role in promoting and promoting.

In the next few years, domestic caprolactam production and sales will continue to increase rapidly. It is estimated that the domestic demand for caprolactam in 2014 will reach 1 million 700 thousand tons, and domestic capacity will reach 1 million 500 thousand tons, which can not meet the market demand. Therefore, caprolactam production still has great room for development in China.
