Abstract

1536767 Gas cooled crystallisation process BAYER AG 21 June 1976 [26 Feb 1975] 25704/76 Heading B1G A process for the continuous production of crystals from a solution comprises dissipating heat from the solution with gases in a bubble layer. A mixture of a propellant gas and a liquified gas in a controlled proportion is bubbled through the solution whereby the liquified gas is evaporated thereby dissipating heat. Residual crystallisation solution entrained in the spent gases is separated from the gases before sensing the gases. Crystals which have formed as a result of the cooling by the gases are separated from the solution. The mixing of the gases and the solution to be crystallised is preferably carried out in a bubble column fitted with a mixing chamber in its base.
