A distillation system having a plurality of chambers, an input conduit connected to each chamber to deliver an aqueous fluid to each chamber; a pressure reducing valve connected to the input conduit; a waste output conduit connected to a waste collection compartment of each chamber; and condensate output conduit connected to a condensate collection compartment of each chamber. An evaporation wall of each chamber is constructed to maintain an evaporation surface temperature that is greater than a condensation surface temperature of a condensation wall of each chamber. The aqueous fluid forms a fluid coating, which moves down the evaporation wall. A saturation pressure differential is created as water from the aqueous fluid evaporates from the evaporation wall and condenses on the condensation wall forming an aqueous condensate, which moves down the condensation wall and is collected as an aqueous distillate in the condensate collecting compartment.

A process for separating xylenes from a feedstock in which the feedstock is separated into a xylene stream, a benzene rich stream and a light ends stream. Two separation zones may be utilized in which liquid from the first zone sent to a toluene recovery zone and vapor from the first zone is sent to a compression zone. The compressed vapor from the compression zone is sent to the second separation zone.
