中文摘要：连续重整反应系统压力依靠重整产物分离罐压力控制而保持稳定，而重整产物分离罐压力控制与产氢增压机运行状态密切相关。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，而导致的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，问题得到了解决，并对改造前后的运行情况进行对比分析。结果表明，3C控制系统应用后，反应系统压力控制平稳，重整产氢增压机运行稳定并减少蒸汽用量5～10t/h。
英文摘要：The pressure of the continuous catalytic reforming reaction system is kept stable by the pressure control of the separation tank of reforming products, and the pressure control of the points tank of reforming products is closely related to the operation state of the hydrogen-producing booster compressor. As the pressure control scheme of the separation tank of reforming products and the anti-surge control scheme of the hydrogen-producing booster compressor are not applicable, which leads to the pressure’s higher fluctuation of the reaction system, unstable running state and high energy consumption of the compressor, transforming the control system of the hydrogen-producing booster compressor with 3C(Compressor Controls Corporation) control system, and the operational aspect is analyzed and compared in this article. The results indicate that the 3C control system has been successfully applied to improve the stabilization of compressor operation and system pressure control, reduce steam consumption by 5 ~10t/h.
