蒸汽减压站自控系统的巧设计

Ingenious Design for the Automatic Control System of the Steam Decompression Station

蒸汽是石油化工装置中最重要的物料。随着石油化工工业的迅猛发展 ,蒸汽在其中扮演着越来越重要的多重角色。因此 ,对蒸汽系统的平稳控制 ,对石油化工生产装置平稳、高效地运行是至关重要的。传统的蒸汽减压站自控系统基建投资大 ,紧急情况下靠人工手动操作稳定蒸汽压力系统 ,往往造成生产的波动或大面积的停车。针对传统蒸汽减压站自控系统的弱点 ,提出蒸汽减压站自控系统的优化设计方案 ,该方案得以在大型生产装置成功应用。新方案不但节省了大量的基建投资 。

The design for the automatic control system of the steam decompression station is introduced.Overcoming the weakness of the traditional control system of a steam decompression station,the optimized design scheme,which has been used in a large scale production plant,was put forward.This design not only saved the capital investment and also achieved the good benefit.
