PVC树脂浆料汽提系统工艺及管道设计要点

PVC Resin Slurry Stripping System Process and Key Points for Pipeline Design

介绍了悬浮法PVC树脂聚合生产工艺技术、PVC浆料汽提生产工艺技术,通过分析温度、压力、停留时间对PVC浆料汽提效果的影响因素,结合汽提塔工艺计算的具体数据,对汽提系统浆料管线配管、汽提塔配管的设计方面提出改进方法和建议,并对今后PVC浆料汽提过程设计中应注意的问题进行论证并提出注意事项和意见。

The polymerization production technology of suspension PVC resin and PVC slurry stripping production technology was introduced. Through analysis of the influence of temperature, pressure, residence time on PVC slurry stripping effect, combined with the concrete data of stripping tower process calculation, improving methods and suggestions for slurry pipeline piping and stripping tower piping of stripping system were provided, and the problems needing attention during the design of PVC slurry stripping process in the future was demonstrate, and the announcements and sug- gestions were also proposed.
