摘　　要：简要介绍了环氧氯丙烷装置的主要工艺流程,叙述了基于WebField ESC-100控制系统的总体设计方案,详细阐述了丙烯氯化过程中反应温度和原料配比的综合控制采用串级双闭环比值控制方案、对串联双塔的物料平衡控制采用了双冲量均匀控制方案,总结了两种控制方案的现场应用情况。The main process flowsheet in the epichlorohydrin production unit is introduced. The design scheme based on WebField ECS-100 is described. , It is described in detail that the universal control of reaction temperature and feedstock ratio adopted two close loops in series ratio value control scheme in propylene chlorination reaction, dual impacts uniform control scheme is adopted for the materials balance of the two towers in series. Field application situation with adopting two control schemes is summarized.
