In the atmospheric and vacuum distillation unit, heat reflux is used for the condensation in the first stage at the top of the tower in order to reduce corrosion of the cooling equipment at the tower top as well as within the tower itself. The mechanism behind this anti-corrosion approach is not clear; could someone please explain it?
Was it written wrong? Heat reflux can only occur with two stages of condensation; where would heat reflux come from with just one stage of condensation?
