半再生催化重整装置工艺流程及设备的改进与探讨

IMPROVEMENT AND DISCUSSION ON PROCESSSCHEME AND EQUIPMENT OF SEMI-REGENERATIVECATALYTIC REFORMER

本文介绍了半再生催化重整装置在原料的预处理及重整反应、分离两方面，在工艺流程和设备上的改进，分析研究了预处理及重整生成油液体回收的流程及控制方案。还介绍了两种流向的重整径向反应器──上流式中心管反应器和下流式中心管反应器，并建议半再生催化重整装置应采用上流式中心管反应器。

The improvement on process and equipment of the feed pretreatment unit and the reformate separation section of the reformer is presented. Process and control systems of both the pretreaterand the reformate liquid recovery are analysed and studied. Two types of radial reactor (up-flow anddown-flow centre pipe reactors) are also introduced. For semi-regenerative catalytic reformer, the up-flowreactor is preferred.
