摘要： 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. There is continuously recovered from the second evaporative-crystallization zone a slurry having a total solute or solids content of about 86-94% by weight and containing the solute crystals of desired crystal size.
