摘要
用落入式量热计首次系统测定胜利原油从125℃到525℃的16个窄馏分在不同温度下的焓值,并用抛物线方程进行了焓与温度的关联。讨论美国石油学会推荐的馏分焓计算式对胜利原油馏分的适用性。研究馏分的焓与馏分其它物性间的关系,提出两个经验关联式,关联值与试验值间的平均相对偏差分别为1.85%和1.88%,结果令人满意。
The liquid enthalpies of sixteen petroleum cuts ranging from 125℃ to 525℃ of the Shengli crude have been measured by a dropping block caloriimeter. The relationship of the enthalpy with the physical properties such as mean boiling point, density and viscosity was studied. Two empirial correlatons were proposed with overall average absolute deviation hetween experimental data and calculated values of 1. 85 % and 1.88 % respectively. The adaptation of the enthalpy estimation method recommended by API to the Shengli petroleum cuts were also investigaed.
