Abstract
<PICT:0353392/III/1> In a process for freezing liquids, particularly for precipitating wax from oils such as petroleum or shale oils, the liquid to be treated is cooled first in vessels 10, 11, and 12 by chilled liquid from the final separating tank 22, then in vessels 13, 14 and 15 by brine cooled by an evaporator 38 and finally in vessels 16, 17, 18 directly by the evaporator of a refrigerating plant. The cooling in vessels 10, 11, 12 is regulated by recirculating some of the chilled liquid through the valved pipe 30 while that in tanks 13, 14, 15 is regulated by short-circuiting the brine circulation through a tank 35. Refrigerant vapour from the evaporators in vessels 16, 17, 18 may return through pipe 61 to the compressor or absorber of the plant 45 or it may be withdrawn by pump 58. By the operation of valves A, B, 47, and a valve in pipe 61, the pressures in the evaporators may be varied individually to regulate the cooling in each vessel. Mechanical stirrers are provided in tanks 16, 17, 18.
