摘要： in the process of the present invention an aqueous solution is flash vaporized under a reduced pressure to form, simultaneously, a low pressure water vapour and ice crystals. The ice formed may, if desired, be purified and is then melted inside thermally conductive conduits under a high pressure of, for example, 600 atm. The low pressure water vapour is desublimed to form ice on the exterior of the conduits The latent heat of desublimation released may be utilized in supplying the heat needed in the ice-melting operation. The .desublimate is removed intermittently by an in-situ dissolution operation utilizing an aqueous solution such as the feed solution. A substantially equivalent amount of ice is formed inside the conduits by an exchange freezing operation. The ice so formed is also melted.
An apparatus is provided for carrying out such a process

摘要： Le procédé décrit utilise des équipements pour effectuer des étapes de transformation avec phases multiples solid-liquide-vapeur de congélation par le vide, de congélation par distillation à voie humide, de cristallisation par le vide et de congélation eutectique avec réfrigérant primaire. Tous ces processus nécessitent des opérations de vaporisation et de cristallisation simultanées. Le procédé de la présente invention consiste: (1) à répartir la solution sur une surface rotative (53) pour former des films liquides, (2) à soumettre les films liquides à des opérations de vaporisation et de cristallisation simultanées, (3) à retirer les cristaux des surfaces (53) et (4) à transporter les cristaux vers la prochaine zone de traitement. Les surfaces (53) peuvent être constituées par des vis rotatives avec pas de vis en prise entre eux ou par un groupe de disques placés sur des arbres rotatifs. Les vis sont partiellement immergées dans la solution et des éléments des vis sont mouillés lorsqu'ils sont en rotation dans le bassin.

摘要： A wet and dry distillative freezing process is provided which comprises (a) a first step of transforming a liquid feed mixture into a first solid-liquid mixture, denoted as K-1 mixture, by either a conventional freezing operation or a wet distillative freezing operation, (b) a second step of washing the K-1 mixture with a wash liquid to thereby form a second solid-liquid mixture, denoted as Ko mixture, and an impure liquid Lo, and (c) a third step of subjecting the Ko mixture to a dry distillative freezing operation to thereby form a mass of refined solid phase, denoted as S1, and a low pressure vapor V1. Various wash liquids may be used in the crystal washing step. It is important to note that the wash liquid used does not have to be a pure liquid but may contain some volatile impurities. This is so, because the volatile impurities in the wash liquid will be taken up in the Ko mixture and will be removed in the dry distillative freezing step. Convenient wash liquids to use are (a) a mass of the feed liquid, (b) a mass of the condensate liquid, and (c) a part of the product liquid. One may also use a solution containing the crystallizing component and a selected volatile component as a wash liquid.

摘要： A crystallization separation process for separating an at least partially liquid mixture containing two volatile components (A and B) the two components forming a binary system in which the vapor pressure ratio of A:B is 0.1 to 10 at the B-triple point and is less than the ratio of the heat of sublimation to the heat of melting of the B-component at the B-triple point, the constant pressure phase diagram having a B-enriched solid-vapor two phase region covering a substantial concentration range above the three phase state temperature and a B-enriched solid and liquid region below such temperature wherein a first vapor mixture and first condensed mass are formed by vaporizing the two components in a first zone at a temperature and pressure lower than the triple point temperature and pressure, the first condensed mass comprising a mother liquor and a solid phase which is B-enriched, the heat released in the formation of the solid being utilized to vaporize the volatile components.
Such process can be extended to a gas mixture containing two volatile and condensable components (A and B) into substantially pure B and a B-lean component, in which heat is removed from the gas to cause part of the B to desublime, the A remaining in the vapor stream, the vapor stream then having heat removed therefrom while the vapor is at a temperature and pressure below the B-triple point values thereby causing formation of a further condensed mass.
