다단 담수화설비의 열평형계산

Traditionally, Middle East area is suffered from the lack of water. In addition, as growing the global industrialization, human is faced with the shortage of water resource at present, which makes the desalination system the promising business. Recently, many domestic engineering companies focus on the desalination plant market because it will be promising business in the next few decades. This study was performed to evaluate the theoretical heat balance calculation for multi-stage evaporating type desalination system, especially Multi-Effect Desalination (MED). In MED system, the steam evaporated in the first stage is used for the heating source of the second stage and this process is repeated for the next stage. Therefore, this heat balance calculation method from this study will be highly useful to design the MED system.
