Abstract
A method and apparatus for separating components from a mixture includes a condensing surface located in a high vapor concentration region above the source of evaporated liquid. The evaporated liquid is condensed on the condensing surface. The condensed liquid is removed from the condensing surface while it remains liquid, using substantially capillary forces. A plurality of open grooves are formed on the condensing surface. The grooves channel the condensed liquid on the condensing surface away from the mixture. The grooves can be capillary grooves which satisfy the Concus-Finn Inequality.

A method of separating components from a mixture that is open to the environment comprising:
- supplying admixture to a location spaced within 1 m of a condensing surface without passing the mixture through the condensing surface, wherein the mixture and the condensing surface are open to the environment;
- at the location spaced within 1 m from the condensing surface, separating at least one component from the mixture to create a vapor of that component at an evaporating surface of the source of vapor;
- condensing the vapor an the condensing surface to create a condensate without any condensate impregnating the condensing surface;
- and
- removing, using substantially only capillary forces, the condensate from the condensing surface while the condensate remains in the liquid state.

- at the location spaced from the condensing surface, separating at least one component from the mixture to create a vapor of that component;
- condensing the vapor on the condensing surface to create a condensate without any condensate impregnating the condensing surface;
- removing, using substantially only capillary forces, the condensate from the condensing surface while the condensate remains in the liquid state;
- and
- spacing the condensing surface from the location of the mixture at a distance selected to control the rate of component separation.
