  • Apparatus for solid/liquid separation by vaporization and condensation
    Patent number: 4482432
    Abstract: A continuous process of spreading a film of a solids/liquid admixture over walls of a chamber, maintaining a saturated vapor atmosphere within the chamber, vaporizing liquid of the film to provide the saturated vapor and solids, discharging the saturated vapor and solids from the chamber and condensing the discharged vapor is effected in a hollow module having two spaced-apart chambers, one within the other, and means to move saturated vapor from the inner chamber to the outer chamber.
    Type: Grant

  • Solid/liquid separation through liquid vaporization and condensation, and apparatus therefor
    Patent number: 4292121
    Abstract: A solids/liquid admixture is introduced into an atmosphere (temperature and reduced pressure) in which the liquid is immediately converted to a saturated vapor and thus relieved of associated solids, which are withdrawn. The saturated vapor is then conducted to a surface on which it condenses and from which it is collected. Suitable apparatus is provided in the form of modules, which are efficiently operated in multiples of four in a common temperature-stabilizing medium.
