Heat Exchangerless Heat Transfer of Immiscible Fluids

摘要

The heat exchangerless membrane system optimizes heat transfer between a set of two immiscible fluids such that the second of the two immiscible fluids having an additive, notably an additive that makes the second fluid corrosive, is infrequently in contact any heat exchangers that would make the heat exchanger subject to corrosion. This membrane system is capable of separating the two immiscible fluids downstream of the heat transfer process, such that heat transfer can repeat the cycle again in an energy efficient manner.

主权项

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.
