苯胺装置紧急停车系统(ESD)的设计探讨

从安全生产角度出发,提出在苯胺装置设置独立的紧急停车系统(ESD)。作为安全保护系统,其权限优先于生产过程控制,实时在线监测装置的安全性。首先阐述了采用ESD的背景,然后对现有苯胺装置的生产状况和自控水平进行了介绍,提出采用ESD的必要性,最后从ESD系统设计选型、ESD功能及特点、切断阀的选用以及ESD联锁设计中需要注意的几方面详细介绍了苯胺装置紧急停车系统的设计选型与应用。

Design and discussion of emergency shut-down device (ESD) system of aniline production plant

Setting up independent emergency shut-down device （ ESD ） system for aniline production plant from safety operation standpoint is put forward. As a system to protect facility, its security level rises above the safe operation mode, which can ensure the safety of facility at real time under online control. The ESD application background is expounded ; the current production status and automatic control system applied in aniline production plant are presented, and the necessity of adopting ESD system in aniline production plant is pointed out. The design, choice and application of ESD system in aniline production plant are described in detail from several aspects including the function and feature of ESD system,the selection of shut-off valve and the interlock design of EDS.
