The efficiency of the distillation column decreases

The efficiency of the distillation tower for producing industrial naphthalene has decreased. Could everyone with experience help analyze where the problem lies? 1. Heating – heat transfer oil. 2. The tower uses stainless steel structured packing. 3. Cooling by water circulation

I forgot to mention that it’s fractional distillation during intermittent operation

Reply to 1# han68568: 1. What are the specific manifestations of \"reduced efficiency of the distillation tower\"? How do you collect your raw materials? 2. Is there a problem with the raw material? Was the separation of naphthalene oil in the previous step not thorough, resulting in impurities? Intermittent distillation is flexible with a large range of adjustment possibilities.

Does a decrease in tower efficiency mean a reduction in load while maintaining separation quality? Please make it clear, OP
