Abstract
A process is provided for separating trace amounts of water-immiscible, volatile organic liquids dissolved in aqueous media whereby the aqueous media are subjected to vapor stripping under vacuum at about ambient temperature in conjunction with a heat pump which indirectly recovers the energy of vaporization in its cold loop and returns such energy to the vaporization of the aqueous media in its hot loop. Inasmuch as the entire process is conducted at ambient temperature, there is little loss of energy to the environment and processing energy is recovered and reused to the application of a heat pump system.
