I/A S在延迟焦化装置中的应用

The Application of I/A S in Delayed Coking Plant

应用I/A S对分馏塔顶压力与气压机入口流量选择控制,介绍工艺机理,改进前、后控制方案,利用计算模块CALC实现程控开关,还介绍了气体报警在I/A S上的实现.

The select control strategy of the top pressure of fractiontor and the inlet flow of the compressor is implemented by I/A S. The mechanism of process technique, the control strategies before and after improvement are introduced. The programmable switching has been implemented by using calculation block CALC. Also the alarm on gas is accomplished on I/A S.
