应用3C控制系统对重整产氢增压机的改造及分析

Application of 3C control system in reforming hydrogen-producing booster compressor and operation analysis

连续重整系统压力依靠重整产物分离罐压力控制而保持稳定,而压力控制与产氢增压机运行状态相关。由于重整产物分离罐的压力控制方案和产氢增压机的防喘振控制方案不适用,导致了反应系统压力波动较大以及压缩机自控运行不稳定、能耗高等问题。应用3C(Compressor Controls Corporation)控制系统对重整产氢增压机控制系统进行改造后,问题得到解决,文中对改造前后的运行情况进行了对比分析。

The pressure of the continuous catalytic reforming reaction system was kept stable by the pressure control of the separation tank of reforming products which was closely related to the operation state of the hydrogen-producing booster compressor. The mismatch between the pressure control scheme of the separation tank of reforming products and the anti-surge control scheme of the hydrogen-producing booster compressor lead to high fluctuation of the reaction system pressure,unstable operation of automatic control system and high energy consumption of the compressor. After transforming the control system of the hydrogen-producing booster compressor with 3C(Compressor Controls Corporation)control system,the problems were solved. This paper made a comparison and analysis on the operation status before and after transformation.
