Abstract
A distillation column including a plurality of alternating plates and spacers stacked in a z-direction is provided. The plates include a respective liquid channeling network on a top surface thereof, a respective vapor opening, and a respective descending ramp. The respective descending ramps abut a respective liquid feed location of the plate immediately below to form a continuous liquid channeling network. The respective vapor openings of adjacent plates are located on opposite sides of the distillation column and form a continuous S-shaped vapor channel defined by the plurality of alternating plates and spacers, and the respective vapor openings. Systems including such distillation columns and processes of distilling a fluid mixture are also provided.
