How to reduce the amount of vapor at the top of the rectification column? The type of trays, their efficiency? I have a lot of top reflux in model the unisim program. I am asking for an answer and best regards.

[@ChemicalEngineeringGuy]

if you have a lot of vapor on tops, then you are most likely using very high T profiles, or the condenser T is higher than it should be

@@ChemicalEngineeringGuy Thank you very much for your answer

how do I chage distillate-gas ratio from 1:10 to 1:20?
