Based on correlations of flow resistance and sea water boiling point elevation (BPE) applicable to the low-temperature multiple effect distillation (LT-MED) desalination plant
the thermodynamic losses in a large-scale LT-MED desalination plant were calculated and analyzed
including the distribution and proportion of various thermodynamic losses caused by BPE and flow resistances. The effect of the number of evaporator/condenser on thermodynamic losses was studied. The result indicates that
for a large-scale LT-MED desalination plant with constant production capacity
the total thermodynamic losses increases with the number of effects. The thermodynamic loss caused by BPE constitutes the highest proportion while that by the flow resistances can not be ignored. According to the analysis on the loss
the operating characteristics of LT-MED desalination system are summarized as small temperature difference
