Efficiency of a vortex contact stage in thermal distillation

Abstract

The results of studying the process of distillation in a column with 21 vortex contact stages have been reported. The partial condensation of an ascending ethanol–water mixture vapor at the contact stages has been shown to intensify the mixture distillation process by threefold compared to adiabatic distillation. The process parameters that intensify heat and mass transfer in thermal distillation have been established. Some relationships for estimating the efficiency of a vortex contact stage have been derived.
