Claim Text:
1. A heat exchangerless membrane system comprised of a first fluid having an evaporation temperature; a second fluid having an evaporation temperature wherein the second fluid's evaporation temperature is at least 2 degrees Celsius lower than the first fluid's evaporation temperature; a porous membrane comprising a porous substrate having a surface that is both superhydrophilic, having a first apparent advancing dynamic contact angle of less than or equal to about 5° for second fluid and oleophobic having a second apparent advancing dynamic contact angle of greater than or equal to about 90° for a preselected first fluid; a heat exchanger operable to transfer thermal energy into or out of the first fluid upstream of a heat exchangerless tank, the heat exchangerless tank is operable for heat transfer by direct contact of the first fluid and the second fluid; whereby the porous membrane is operable to separate the first fluid from the second fluid downstream of the heat exchangerless tank; and wherein the first fluid is at least partially immiscible with the second fluid.
