1 国内聚丙烯树酯生产现状 目前国内聚丙烯树脂生产装置分为三大类型:一是前期由国外引进生产技术建成的大型聚丙烯生产装置,就生产工艺看,前期建成的大型生产装置,主要是采用液相本体-气相本体组合法工艺。二是我国自行开发的中小型聚丙烯生产装置,主要采用的是由我国自行开发的间歇式本体法生产工艺;三是1998年新近建成燕山石化公司年生产能力20万t的聚丙烯生产装置,该装置也是目前国内单套生产能力最大
1 Polypropylene resin production status in China Currently, the domestic polypropylene resin production equipment is divided into three types: one is a large-scale polypropylene production device that was built in the early stage by foreign introduction of production technology. In terms of production technology, large-scale production devices built in the early stage are mainly The liquid phase bulk-gas phase bulk combination process is used. Second, China’s self-developed small and medium-sized polypropylene production equipment, mainly used by China’s self-developed intermittent bulk production process; Third, in 1998 newly built Yanshan Petrochemical Company’s annual production capacity of 200,000 tons of polypropylene production equipment, The device is also the largest domestic single set of production capacity
