For example, when the components become lighter: (1) In conventional distillation, it is possible to reduce the amount of steam used for heating or increase the reflux rate; if the change in components is significant, it may be advisable to lower the feed inlet position of the tower. (2) In extractive distillation towers, to maintain a constant concentration of solvent on the tray, the heating intensity can be reduced. As the components become lighter, more oil accumulates on the trays, resulting in a decrease in the solvent concentration there; therefore, it is necessary to increase the amount of solvent fed into the tower. Of course, all these adjustments need to be fine-tuned based on the composition of the feed and product analysis
I hope we can have more discussions on this issue. Thank you
