Continuous reforming normal pressure regeneration system and control method thereof

Abstract

The invention relates to the field of catalyst reforming regeneration, in particular to a continuous reforming normal-pressure regeneration system and a control method thereof. The continuous reforming normal pressure regeneration system comprises a first locking hopper LH-1 and a second locking hopper LH-2, and in the first locking hopper LH-1, a reactor reduction area LS-3502, a first buffer hopper FA-351, a first collecting hopper FA-352 and a first lifter FA-353 are sequentially communicated; the first lifter FA-353 is always communicated with a separation hopper FA-354 of the second locking hopper LH-2, and the first lifter FA-353 is always connected with a hydrogen source; and a regenerator DC-351, a second buffer hopper FA-356, a second collecting hopper FA-357 and a second lifter FA-358 in the second locking hopper LH-2 are sequentially communicated with one another. The first locking hopper LH-1 and the second locking hopper LH-2 are controlled through related steps respectively. The automatic control level of the device is effectively improved, the operation intensity of personnel is reduced, the operation stability is improved, the automatic control level is improved, the valve fault alarm function is added, the rapid handling capacity of the personnel is improved, and the fault maintenance time is shortened.

Description

Technical field [0001] The present invention relates to the field of regenerative reforming catalyst, particularly relates to a continuous regenerative reforming system and a control method for a normal pressure. Background technique [0002] Both catalysts commonly used in current industry continuous regeneration process systems, one of which is axially overlay a continuous reforming process system developed by UOP, the process control system of the conventional system, the key components of the controller for the non-redundant I set up, many times when the production process control step sequence errors, a reboot to resume normal work after the entire process system must stop cold, but after a cold shutdown system recovery cycle is long, tedious process operation, high labor intensity of the operator. Practice need for a fully functional, flexible operation of controllable continuous catalyst regeneration unit control system, improve the stability of operation of the device. I...

Problems solved by technology

[0002] At present, there are two kinds of catalyst continuous regeneration process systems commonly used in the industry, one of which is the axial overlapping continuous reforming process system developed by Universal Oil Company of the United States. The existing control system of this process system has no redundancy for the key components of the controller. In other settings, when there are many control step errors in the production process, the entire process system must be restarted after a cold shutdown to resume normal work. However, after a cold shutdown, the system recovery period is long, the process operation is cumbersome, and the labor intensity of the operators is high.
