Abstract
This article describes the development process of domestic PVC industrial production technology and the current situation, including the process, polymerization methods. This design uses calcium carbide, suspension polymerization produce PVC. An annual output of 201,000 tons of polyvinyl chloride (PVC) whole section process design, the main process of acetylene, vinyl chloride synthesis, polymerization production processes, stripping process, centrifugal drying process conducted five process material balance, heat balance process equipment and accurate calculation and selection of the three aspects puting base. This design requires the use of derived seven 70m3 (Ⅱtype) stainless steel polymerization reactor operated in parallel, seven 70m3 discharge chute, thirteen WL-630 centrifuge. While drawing the whole process flow diagram, PVC polymerization process flow diagram section, major equipment polymerization section plane, elevation layout, PVC stripping process flow diagram with control points, the fact
