A distillation system is provided for recovering water from sea water and other polluted water source. The system has a heat engine embodying Carnot cycle and a Rankine cycle formed by heat exchangers, flash evaporator and condenser. Burnt gases from the engine such as a jet engine no longer fit for flying are directed into a duct where the exchangers are located. Sea water is pumped into the heat exchanger for preheating by residue heat in the duct and then into the exchanger for further heating. A recirculating pump raises water pressure in the exchanger for increasing boiling point to about 165° C. The heated water is fed into the evaporator where it changes into vapour and condensed into water by the condenser. The jet air stream is used to create Venturi effect for maintaining sub-atmospheric pressure in the evaporator. Any solid left in the evaporator is removed by a transfer mechanism.
A water distillation system comprising feed water means arranged to supply feed water to heat exchange means, a heat generating engine arranged to supply a stream of hot fluid to the heat exchange means for heating the feed water in the heat exchange means, a water flash evaporator arranged to receive the heated feed water from the heat exchange means for evaporating the heated water, and a condenser arranged to receive vapor formed from the heated feed water in the evaporator and to convert the vapor into water, wherein the heat generating engine is a jet engine arranged to supply a stream of hot fluid in the form of a gas to the heat exchange means and further comprising air extraction means arranged so that the gas stream is induced to create a partial vacuum in the flash evaporator, a pump for drawing the feed water into the heat exchange means and control means being arranged to dynamically control the temperature, flow and pressure of the water.
