提出了一种关联不同盐溶液汽液平衡实验数据的方法。对数多项式表达式用于数据的相关性。最多可以使用五条不同的曲线来拟合整个浓度范围内的数据。得到了氢氧化钠水溶液和三元硝酸盐混合物的关联式。结果表明，从预测汽液平衡数据的误差百分比来看，该方法比现有方法更准确。 水蒸汽压和饱和温度的关联误差极低，平均误差小于0.1%。得到了氢氧化钠水溶液的结晶曲线。开发了一个通用的计算机程序来计算所有必要方程的系数。这些方程对于预测吸收式热泵模拟程序所需的汽液平衡数据非常重要。还介绍了NaOH和三元硝酸盐溶液的具体结果。 单位:SICitation:Symposium，ASHRAE交易，1988年，第94卷，pt。2、渥太华

A method is presented to correlate experimental vapor-liquid equilibrium (VLE)data for different aqueous salt solutions. Log-polynomial expressions are used for correlation of the data. Up to five different curves may be used to fit the data over the entire range of concentration. Correlations are obtained for aqueous solutions of sodium hydroxide and a ternary nitrate mixture. The results show, from the percentage error in predicting VLE data, that this technique is more accurate than existing methods. Error in correlating vapor pressure and saturation temperature for water is extremely low, the averagee error being less than 0.1%. The crystallization curve is also obtained for sodium hydroxide-water solution. A general computer program is developed to compute the coefficients for all the necessary equations. These equations are important in predicting VLE data required as input for an absorption heat pump simulation program. Specific results for NaOH and ternary nitrate solutions are also presented.Units: SI
