| abstract | 1,105,489. Concentrating liquids by freezing. PHILLIPS PETROLEUM CO. 2 Aug., 1965 [14 Aug., 1964], No. 33015/65. Heading F4H. In a process for separating the components of a liquid mixture by freezing, the crystal/ mother-liquor slurry from a freezer 2 is passed to a separator 16 from which the motherliquor is withdrawn at 9, the crystals are passed to a mixing vessel 18 where they are re-slurried with un-processed liquid from line 13, the slurry is passed to a purification column 20, and the mother liquor is withdrawn from an intermediate filter section 24 of the column and recycled through line 17 to form part or all of the liquid supply 1 for the freezer. The column further includes a reflux portion 30 and a heater 32 for melting the crystals, the melt being withdrawn through line 23 to which a pulsating pressure is applied by means 36. The freezer 2 is of the jacketed type including a scraper 8 but may be replaced by a direct contact heat exchanger. Liquids which may be treated in the process are sea-water, caprolactam, hydrocarbon mixtures such as para and meta-xylene and combinations of benzene n-heptane, carbon tetrachloride, ethyl alcohol, cyclohexane, methyl cyclohexane, toluene, chloroform, acetone and ethyl benzene, and food products such as grape, orange, lemon, pineapple, apple and tomato juices, vegetable juices, milk, beer, wine, coffee and tea. A quantitative example of the process as applied to the concentration of beer is given. |
