The Process Design Of An Annual Output Of10,000Tons Of Special PVC Resin

In recent years, because the capacity of domestic PVC expanded too rapidly,coupled with the worldwide economic crisis and the recession of real estate industry,and the production capacity of PVC greatly exceeds the market demand. Industryoperating rate remained at50%to60%.The market price is low. Almost the entiretrade deficited.Therefore, some enterprises that have strong technical strengthgradually reduce the production of conventional resin, turning it into higher marginspecial resin.This is a preliminary design of an annual output of ten thousand tons of specialpolyvinyl chloride (PVC) polymerization process. Now mainly for the production ofordinary type PVC manufacturers as an additional device. In this paper, the market ofgeneral and special resin, the technology and the application of polyvinyl chloride(PVC) were detailed.The production technology of polyvinyl chloride (PVC) wasdetermined. On the basis of determined the production process, material balance, heatbalance, equipment selection etc. were done. The design fully considers theparticularity of special resin production process conditions. The design has strongsuitable of the temperature and pressure, the special raw material joining process, Thedesign has applicable to the production of the specified varieties of special resin.
