  • Two stage continuous crystallization apparatus with controls
    Patent number: 4056364
    Abstract: A crystallizable solute is crystallized from a solution containing the same by introducing a solution of said solute into a first stage evaporative-crystallization zone together with seed solute crystals. Within the first stage evaporative-crystallization zone the solution is concentrated to yield a saturated first stage concentrate containing crystals of said solute. The crystals of said solute are substantially larger than said seed crystals and are suspended in a solution more concentrated with respect to said solute than the solution supplied to said first evaporative-crystallizaton zone. A stream of said first concentrate is removed from said first evaporative-crystallizaton zone and transferred to a second evaporative-crystallization zone for further concentration or crystallization of solute and for the production of solute crystals of increased size.
    Type: Grant
    Filed: January 19, 1976
    Date of Patent: November 1, 1977
    Assignee: Amstar Corporation
