A process and an apparatus is presented for at least partially extracting a liquid from an aggregate, by evaporation in a stream of carrier gas, followed by separation of at least a portion of the evaporated liquid from the stream of carrier gas. The separation comprises expanding the higher moisture contents stream to a lower pressure so as to effect cooling and resulting liquid condensate from the gas stream, recompressing the cold stream with retained latent heat of vaporization thereby further heating the stream, and discharging the resulting heated stream with the lowered moisture content at an appropriate section of the circuit. In accordance with the present invention, the expansion and the compression take place in a wave pressure exchanger.

A process for at least partially extracting a liquid from an aggregate by evaporation of the liquid and dispersing the resultant vapors in a stream of carrier gas in an open or closed circuit and for separating at least a portion of said vapors from said stream of carrier gas, said separation comprising: (a) at least partly in a rotary wave pressure exchanger, by at least one step of wave pressure exchange including furnishing energy to a compression step described in (c) below, expanding carrier gas containing such vapors to a lower pressure for cooling the gas and thus condensing at least a portion of such vapors; (b) separating resulting liquid condensate from the gas; (c) returning gas recovered from (b) with retained latent heat of vaporization to said wave pressure exchanger and compressing the returned gas by at least on step of wave pressure exchange including receipt of energy from the foregoing expansion of the gas in (a) above, and thus heating the gas; (d) both said expansion and said compression steps being performed substantially adiabatically.
