悬浮聚合法年产30万吨聚氯乙烯车间工艺设计

摘要

本文概述了聚氯乙烯的性质、应用、发展状况、工艺进展以及聚合过程中的影响因素，在此基础上确定了聚氯乙烯悬浮聚合的生产工艺路线和相关参数。然后在物料衡算、热量衡算的基础上进行了设备选型、车间布置和经济核算。文中还对防火防爆防雷和三废的处理回收等方案进行了简单的阐述。最后绘制了带控制点的工艺流程图、主体设备图和车间布置图。

The process design for PVC workshop of suspension polymerization with annual output of 300000 tons

Abstract

The properties, application, development and the technology progress of PVC were summaried in this paper. After the influence factors of synthesis process discussed, the production of acetic anhydride process route and related parameters are determined, and the material balance and heat balance of main equipments were calculated. Based on this, the equipments selection, workshop layout and economic accounting were accomplished. In addition, the protection of fire, lightning, poison and \process flow chart with control point, the figure of main equipments and workshop layout were drawed.

Keywords: PVC；suspension polymerization；agitated reactor；process design
