重整装置中复杂控制系统在DCS上的实现

The Complex Control Systems in Catalytic Reforming is Realized on DCS

介绍重整装置的燃料气压力控制 ,强制通风加热炉燃烧控制及二级往复式压缩机压力控制系统在分散控制系统CENTUM XL上的实现。控制功能除PID外 ,还有串级 ,低选 ,高选 ,比率 。

It is discussed the pressuse control of flue gas,the combustion control of the forced draft heater,the pressure control of the two-stages reciprocating compressor in the reforming unit and that have been realized on CENTUM_XL.The control functions besides PID,there is cascade,low_signnal selector,high_signal selector,ratio,signal converter and compensation computing.
