The cycle rate of UOP continuous reforming catalysts fluctuates greatly
Thread Content
I currently have a UOP continuous reforming unit; the catalyst circulation rate varies between 40 and 90, while the buffer pressure fluctuates within the range of 0.05 MPa. How should I make adjustments?
I’m a beginner too; when there are fluctuations in the catalyst circulation rate, the only approach is to start by focusing on the control points. The key is to determine whether the locking system is stable, as well as whether there are fluctuations in the secondary air supply volume
My unit is experiencing the same issue you described: severe fluctuations in the instantaneous circulation rate of the closed hopper, ranging from 60 to 80. Later, it was caused by a problem with the lower balance valve of the closed hopper; there wasn’t much that needed to be adjusted, so it will be dealt with at an appropriate time. Pay attention to the effects of burning during regeneration and changes in the level of material in the reduction section.
Check if there are any leaks in the lifting system
