紧急停车系统在合成氨装置中的应用

Application of ESD in Ammonia Plant

在合成氨装置中,用紧急停车系统(ESD)取代DCS,独立地完成装置的安全控制,提升装置的安全度等级。详细地介绍了ESD在合成氨装置的实施过程,并就软硬件平台的搭建,实施过程中的关键点做了详细阐述。

In this article,an example in ammonia plant by replacement of DCS interlock with ESD is introduced.In such way the safety interlock is implementated independently and the safety integrity level is increased.This article explains how to implementate ESD,how to build the software and hardware.
