摘要
用半自动等温外夹套大块型铜热量计测定了辽河原油１０个馏分的高温液体焓值。量热装置用α－Ａｌ２Ｏ３标定，用ＴｉＯ２和正庚烷校验可靠性。原油馏分系实沸点蒸馏得到，文中给出各馏分焓与温度的关联式，关联值和实验值的偏差在±１．６％范围内。还对６个焓值的计算式进行了考察，并提出一个简单的计算式，偏差为４．１％．
Liquid enthalpies of ten different boning range fractions from Liaohe crude were measured at different temperatures with a semi-automatic copper-block calorimeter which was calibrated by alpha-alumina. Correlations between enthalpies and test temperatures were obtained by using the leastsquare method. It is shown that the average deviations were below 1. 6%. The calculated results from several published enthalpy equations in comparison with the measured values were summarized. A simple andrather accurate enthalpy equation is proposed for the fractions of Liaohe crude. The deviations between thecalculations and measurements were within 4. 1%.
