Abstract

See full text

An evaporation system employs a thermocompressor to recover heat associated with a distillate produced by an evaporator and to use the recovered heat to preheat evaporator feedwater. In one example, the thermocompressor produces a thermocompressor discharge that is directed into the deaerator, contacting and preheating the evaporator feedwater passing therethrough. In another example, the thermocompressor discharge is directed through a barometric condenser which contacts evaporator feedwater therein and condenses and in the process preheats the evaporator feedwater.
