多元电解质水溶液的值计算法

Exergy Calculation of Multicomponent Electrolyte Aqueous Solution

本文探讨了有关多元电解质水溶液的炯值计算法。提出根据溶液蒸汽压或离子平均活度系数γ±计算二元电解质水溶液(火用)值的公式。多元溶液的(火用)由相同离子强度的二元溶液的(火用)计算。给出海水淡化系统的(火用)数据和脱盐最小功。

The calculation method of exergy of multicomponent electrolyte aqueous solution is discussed in this paper. From vapour pressure or mean ionic activity coefficient of electrolyte aqueous solution, the exergy of binary solution can be obtained. The exergy of multicomponent solution is estimated from exergy of binary solution at same ionic strength as that of multicomponent solution.
