ENHANCED DISTILLATION
ENHANCED DISTILLATIONIn distillation operations, separation results from differences in vapor- and liquid-phase compositions arising from the partial vaporization of a liquid mixture or the partial condensation of a vapor mixture. The vapor phase becomes enriched in the more volatile components, while the liquid phase is depleted of those same components. In many situations, however, the change in composition between the vapor and liquid phases in equilibrium becomes small (so-called pinched condition), and a large number of successive partial vaporizations and partial condensations are required to achieve the desired separation. In some cases, the vapor and liquid phases may have identical compositions because of the formation of an azeotrope, and no separation by simple distillation is possi…
