摘要：以中原原油常压馏分油为原料,在0.493～1.474MPa压力下,测定了116个窄馏分相平衡常数。考察了Soave(SRK)方程、Grayson-Streed(G-S)关联和GS-SRK关联三个汽液平衡模型,对中原常压馏分油加压汽-液平衡计算的适用性。结果表明,Soave方程预测结果最好,其对平衡常数预测平均相对误差为10.2%,对温度预测绝对平均相对误差为4.7℃。
In the range of 0.493～1.474 MPa, 116 vapour-liquid equilibrium constants of narrow range cut of Zhongyuan atmospheric fractions have been calculated from experimental results. SRK state equation, G-S and GS-SRK general correlation are checked. It is showed that the predicted accuracy of SRK state equation is the best. Its absolute mean percentage deviation is 10.2% for equilibrium constants and its absolute mean deviation is 4.7 for temperature prediction.
