摘要
探讨pH值对丙烯腈产品的回收率、质量、运行周期以及操作稳定性的影响,同时阐述在急冷系统、大循环系统以及撤热水系统当中pH值控制方法,以期能为相关工作提供参考。
This paper is on the control method of pH value in acrylonitrile production process, first discusses the influence of pH value to recovery rate, quality, operation cycle and the operational stability of the acrylonitrile product, at the same time, expounds pH value control methods in the quench system, circulation system and withdrawal of hot water system, so as to provide reference for the related work.
