摘　　要：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。Based on the experimental data of vacuum equilibrium vaporization of atmospheric residue from the Liaohe, Daqing, and Shengli crudes as well as the Luning-pipeline transported crude, correlations of flashing pressure and temperature with vaporizing fraction, of vaporizing fraction with gas and liquid phase densities as well as with gas phase molecular weight for each atmospheric residue were obtained respectively through computer processing .These correlations with less deyiations can meet calculation requirements of designing and production departments.
