Abstract

967,675. Refrigerating. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Sept. 25, 1962 [Nov. 8, 1961], No. 40006/61. Heading F4H. [Also in Division B1] Warm cooling water, withdrawn from a refinery or a chemical plant via line 1 into vessel R, is cooled down by partial evaporation of the water as it flows through a series of stages of successively lower pressure, e.g. ten stages V 1 . . . V 10 as in the Figure, the cooled water being withdrawn from the last stage (V 10 ) and pumped back to the refinery. The vapour separated in each stage passes through a line L to a compressor C (preferably of the rotary type) where it is compressed to at least the pressure of the preceding stage, the compressed vapour is combined with the vapour formed in the preceding stage, and the total combined vapour discharged from the compressor C 1 , associated with the first stage V 1 , is passed to a condenser Cd. The condensate may be returned to vessel R via line 2, thereby forming a closed system, or the condensate may be used as drinking water. Non-condensable gases, such as air, are removed from the system by vacuum pump Vc. In order to eliminate superheating of the vapour, caused by compression, water may be drawn from each stage via line L<SP>11</SP>, and injected into the preceding compressor and/or into the vapourline. Alternatively, the condensate from the condenser Cd may be used as injection-water.
