PCT No. PCT/FI92/00277 Sec. 371 Date Jul. 26, 1994 Sec. 102(e) Date Jul. 26, 1994 PCT Filed Oct. 16, 1992 PCT Pub. No. WO93/07953 PCT Pub. Date Apr. 29, 1993.When a vapor-phase mixture is brought in contact with a liquid absorbent kept at a temperature above the condensation temperature of the vapor-phase mixture, the vapor-phase mixture becomes concentrated for those components which are absorbed by the absorbent in small or negligible amounts. In the method according to the invention, the regeneration of the absorbent essentially utilizes the heat of absorption of the absorbed components. The actual absorption process can be isothermal or adiabatic or a combination of these. The method is particularly suited to the separation of vapor-phase mixtures of minimum boiling point azeotropes.
