A process for condensing vapor or mist material onto a thin first liquid film surface, which liquid film is generated and supported on the outer surface of a porous structure. A moving condensable vapor contacts the thin liquid film and is condensed onto the liquid surface. The condensed vapor drains by gravity action into a collection zone, together with a portion of the liquid film material being entrained therein. The vapor or mist material can be either substantially immiscible or miscible in the liquid film. The first liquid is preferably provided in a closed system and is recycled at near ambient temperature and at pressure conditions sufficient to produce the thin liquid film external to the porous structure, which has a porosity of 20-80%. An apparatus including the porous structure and liquid handling system for condensing an upflowing condensable vapor is disclosed. |

DETAILED DESCRIPTION We claim: 1.
A process for condensing a flowing condensable vapor onto a thin film of a liquid, comprising: (a) providing a thin liquid film of a first liquid on an exposed surface of a porous structure, said porous structure having a porosity of about 20-80%, and being oriented at such an angle with a vertical plane that a portion of the liquid film will flow downwardly along the exposed surface of the porous structure and drip from a lowermost edge of the structure; (b) providing a flowing condensable vapor material contacting said liquid film, and condensing said vapor on said liquid film without contacting said porous structure so as to provide a condensate second liquid; and (c) draining said condensate second liquid together with a minor portion of said first liquid from the porous structure.
2.
The vapor condensing process of claim 1, wherein said condensable vapor material is substantially immiscible in said first liquid.
3.
The vapor condensing process of claim 2, wherein said first liquid water temperature is 2.
degree.
-80.
degree.
C.
4.
The vapor condensing process of claim 2, wherein said condensable vapor material is an organic oil, a hydrocarbon liquid, an aqueous solution, or any combination thereof.
5.
The vapor condensing process of claim 1, wherein the first liquid film is substantially stagnant on the exposed surface of said porous structure.
6.
The vapor condensing process of claim 1, wherein the weight ratio of the first liquid on the condensed vapor on the porous structure is within a range of 0.
5/1 to 10/1.
7.
The vapor condensing process of claim 1, wherein said first liquid is recirculated and cooled to maintain the liquid film temperature below the temperature of the flowing condensable vapor material.
8.
The vapor condensing process of claim 1, wherein said first liquid is provided from a closed recirculating system at 0-15 psig pressure.
9.
The vapor condensing process of claim 1, wherein said porous structure is oriented at an angle of 0.
degree
