ABSTRACT:
A distillation system where a saline fluid (10) is pumped into a pressure vessel (14), through a counterflow heat exchanger (16) and heated to boiling. A salt free distillate (20) is separated from the saline fluid (10). The concentrate valve (24) and the distillate valve (26) restrict egress flow. The concentrate valve (24), the distillate valve (26) and the heater (18) are controlled by a computer control system (32) to attain and maintain a desired value of the Ewing Number. The Ewing Number is a dimensionless measure of performance defined as the heat of vaporization of the distillate (20) at standard atmospheric conditions times the distillate (20) mass flow divided by the system power input.
