Kiva" X-Minuet-Version: Minuet1.0_Beta_16 Reply-To: X-POPMail-Charset: Latvian+Russian To: ekh@asker.chembio.ntnu.no Subject: Re: PROST-seminar February 4, 1998 Dear Katrine, The topic of seminar will be "Methods for distilling azeotropic mixtures". I think it may be of more general interest, because "The product areas of distillation" is more specific problem. May be I have to say something about it too, but it will be not a main point. Contents: The methods for separating binary homogeneous azeotrope by distillation with a third component (separating agent) are considered. These methods include homogeneous azeotropic distillation, heterogeneous azeotropic distillation and extractive distillation. The possibility to employ one of these methods depend on the vapor-liquid equilibrium diagram of the ternary mixture of the binary to be separated and the third component. It will be shown that the separation efficiency of homogeneous azeotropic distillation is strongly exaggerated. In some cases the heretogeneous azeotropic distillation is more effective, but the range of feasible entrainers is too narrow. Extractive distillation is less sensitive to the structure of VLE diagram and the range of solvents is broad enough. If you have some objections we can change the item afret my arrival.
