<p>An evaporation process for the separation of a solution into its volatile and non-volatile components by feeding the solution to a calandria where it is heated and partially vaporized and the resulting calandria vapour stream is subjected to vapour-liquid separation for the removal of entrainment, is improved by using an additional and intermediate step in which the calandria vapour is contacted with the feed solution. </p> |
