Despite the fact that the world's need for fresh water is becoming more urgent, the ability to desalinate economically on a large scale still remains a goal rather than a reality. Distillation systems are by far the most widely employed systems for sea water desalination. However, the relatively high costs of these systems' products limits their competence with natural water resources, particularly for agricultural use. In this paper a distillation system is proposed. The system gives high performance ratios at low flashing ranges, which leads to a substantial saving in the distillation plants running costs. The analyses showed that the system has big thermodynamic potentialities.
