Salt water desalination method and desalination plant using MSF desalination unit with improved brine recirculation system

摘要

In order to increase the desalination plant production through improvements in the brine recirculation circuit a new method and a new plant are described. The method and the plant for the desalination of salt water using at least a brine heater (1), a desalination zone of multi-stage flash (MSF) distillation units (2) and an optional separate deaerator (5), wherein sea water is being deaerated and is pumped as a recirculating brine into a heat recovery section (3), where the brine is being condensed and the distillate is won, characterized in that the heat recovery section (3) is at least partially bypassed by the recirculating brine by providing at least one bypass line (22).
