When a vapour-phase mixture is brought in contact with a liquid absorbent kept at a temperature above the condensation temperature of the vapour-phase mixture, the vapour-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 vapour-phase mixtures of minimum boiling point azeotropes. |
