Title: Desalination of Sea Water by Flash Distillation
Inventor: KASSEL CHARLES
IPC: C02F1/16
Filed: 1967-06-12
Abstract: 1,166,149. Evaporators, flash type; desalination of water. COMMISSARIAT A L'ENERGIE ATOMIQUE. 12 June, 1967 [20 June, 1966], No. 27052/67. Heading B1B. Sea water is desalinated by heating it under pressure and then submitting it to evaporation in a series of (e.g. fifty) flash evaporators 20, 27, 22 maintained at progressively decreasing pressures by ejectors 24, 28, 23, one associated with each evaporator, through which series of ejectors a cool liquid, e.g. fresh water distillate and/or a hydrocarbon oil, is pumped at progressively increasing pressures whereby the vapour produced in each evaporator is aspirated from it and condensed in admixture with the cooler liquid flowing through the associated ejector. A hydrocarbon oil, functioning as heat-transporting medium, may be circulated in a closed circuit comprising the evaporation and condensation sections. The sea water feed is preheated under pressure by heat-exchange with fresh water distillate and with residual brine. The preheated sea water is de-aerated and then mixed with hot hydrocarbon oil which has been heated by heat-exchange with steam produced in a nuclear reactor. The mixture of sea water and oil is injected tangentially into the first flash evaporator 20, and then into the following evaporators. The mixture of residual brine and oil flows from the last evaporator 22 into a separator. The separated oil is cooled by addition of a small proportion of the fresh water distillate, and the mixture is pumped successively through ejectors 24, 28, 23. The mixture of fresh water distillate and oil leaving the last ejector 23 is passed to a cyclone separator, and the separated oil is recycled to the steam-heater. The vapour leaving evaporator 27 is used to deaerate the preheated sea water feed, and is then drawn into ejector 28 which discharges into cyclone 26 where the gases are purged from the system.
