CPVC和PP-H在烧碱装置中的应用

Discussion on Application of PVC and PP- H in Caustic Soda Plant

简要介绍烧碱装置的主要工艺流程、工艺物料特性和氯化聚氯乙烯(CPVC)及均聚聚丙烯(PPH)管道材料的物理特性;详细推算CPVC和PP-H管道材料的温度压力表,得到CPVC和PP-H管道在烧碱装置的应用范围及注意事项。

This paper briefly describes the main process flow of caustic soda plant,process material characteristics and the physical properties of chlorinated polyvinyl chloride( CPVC) and polypropylene homopolymer( PP- H) piping materials. The temperature and pressure of CPVC and PP- H piping materials are detailed and figured out in tables. Present the range of application and precautions for CPVC and PP- H piping in caustic soda plant.
