<p>Process for substantially quantitatively removing and recovering a volatile, organic, water-immiscible wetting liquid from a solid material which is wet therewith, which process comprises intimately contacting the solid material first with the superheated vapor of a water-immiscible, organic stripping liquid and thereafter with dry steam, said contacting taking place in an environment substantially free of noncondensable gas, condensing the mixture of organic vapor and steam to form a two-phase liquid mixture consisting of liquid organic phase and liquid water phase, and separating the liquid organic phase and the liquid water phase.</p> |
