Regarding the issue of poor separation efficiency in fractional distillation packed columns

I encountered a problem during the production process: every time the packing tower is started up, there are sudden fluctuations in the heating level (insufficient heating); or when the tower stops operating suddenly and then starts up again after a short time, the separation efficiency of the tower becomes very poor, and it’s difficult to ensure that both the quality of the product at the top and at the bottom of the tower meets the required standards. It’s possible to increase the production volume temporarily, but not on a sustained basis. Even after switching to full reflux, it’s still not possible to increase the volume. I seek help from experts – what is the root cause of this problem? How should it be solved?
After flushing the tower, the packing gets contaminated by dirt or there are issues with the distributor.
Is it okay to drive for an extra while longer after starting to increase the volume?
