<p>In order to increase the performances of existing desalination units in term of water production or plant capacity, desalination plant G. O. R. (gained output ratio) or process efficiency and distillate water quality, a method and a plant for the desalination of salt water has at least a brine heater (1), a desalination zone of multi-stage flash (MSF) distillation units (2) and, an optional deaerator (5), wherein a desalination zone comprises a heat recovery section (3) and a heat rejection (4) section for condensing the brine and winning the distillate, characterized by providing at least one steam recirculation line (22) from at least one stage of the rejection section (4) and/or the heat recovery section (3) for the steam produced to a section or stage up-stream with regard to the flashing brine flow.</p> |
