ABSTRACT:
A plate-type distillation/condensation apparatus and a method of using same to separate at least two volatility-differing liquid or vapor components from a mixed fluid stream thereof are disclosed, wherein the apparatus contains at least one flow plate having formed on a common facial surface thereof at least one distillation/condensation chamber containing an inlet port for the mixed fluid stream; a primary flow channel in fluid communication with the inlet port; one heat exchange conduits, wherein (i) a first heat exchange conduit for a first cooling fluid is disposed in a first heat exchange contact with the primary flow channel sufficient to condense at least a portion of a first vapor component into a first condensate phase, or (ii) a first heat exchange conduit for a heating fluid is disposed in a second heat exchange contact with the primary flow channel sufficient to boil at least a portion of a first liquid component into a first vapor phase, and a second heat exchange conduit for a second cooling fluid is disposed in a third heat exchange contact with the primary flow channel sufficient to condense at least a portion of the first vapor phase into a first condensate phase; at least one side outlet port; and an overhead outlet port.
