根据辽河、大庆、鲁宁管输和胜利等原油常压重油减压平衡汽化试验数据，通过计算机处理，对于每种常压重油分别得到闪蒸压力、温度与汽化分率的关联式，汽化分率与气、液相密度的关联式以及汽化分率与气相分子量的关联式。这些关联式的偏差较小，可以满足有关设计、生产部门的运算要求。
According to the experimental data of decompression equilibrium vaporization of crude oil at atmospheric pressure and heavy crude oil, the correlations of flash pressure, temperature and vaporization fraction, vaporization fraction The correlation between rate and gas and liquid density, and the correlation between vaporization fraction and gas phase molecular weight. These correlations have small deviations to meet the computing requirements of the design and manufacturing departments.
