Abstract
Method and apparatus for recycling a water-displacement process fluid that includes an organic liquid and a surfactant, the boiling point of which exceeds that of the organic liquid, maintains a sufficient quantity of organic liquid such that water displaced into the organic liquid is evaporated at least as fast as it is introduced. If the water and the organic liquid are immiscible and exhibit different densities, the resulting condensate can be separated into constituent phases by decanting. The condensed organic liquid and unevaporated surfactant are then available for recycling.
