Design of 16700 tons PVC suspension polymerization process

ABSTRACT

【The design for the 16700 tons of PVC polymerization process design throughout the design file is composed by two parts of the design specification and design drawings. In the design manual, a brief introduction of PVC production status, development trends, performance, and the main purposes highlighted by suspension polymerization as the polymerization process production methods. In the design process, according to the requirements of the design task book to conduct a more detailed material balance and heat balance and the the polymerizer calculation process calculation and selection of equipment, a simple techno-economic evaluation of the entire device . Drawing of the design drawings, design drawings including process flow diagram of the polymerization reactor assembly drawing】

KEYWORDS:PVC ,suspension polymerization process, production process
