This design is the initial design of polymerization section with the annual PVC production capacity of 72,000 tons by suspension polymerization process based on vinyl chloride monomer as raw material. The design is finished according to the outline of design specification requirements of graduation design by collecting information on the chemical design. Development, properties, purpose and the selection of technology of PVC are briefly introduced. The suspension polymerization production of PVC is focused on. On the basis of theory study and combining with production practice, the process and selection of the production method are known well and the material balance, energy balance and the selection of equipment in process design are grasped.
