The Soave Redlich-Kwong（S.R.K.）状态方程用于关联含轻质化合物体系和气态烃体系的相行为。考虑的气体包括H2、CH 4、N2、CO2、CO和SH 2。进行了广泛的文献检索，以获得用于建立相行为的预测程序的二元实验汽液平衡数据。对812个等温数据集（4399个实验点）的气泡压力预测的平均误差为4%。计算系统含有高极性物质，水和甲醇，包括在内。当所提出的方法被用来预测一些典型的石油和相关工业中遇到的三元体系的相行为时，获得了良好的结果。
The Soave Redlich-Kwong (S.R.K.) equation of state is used to correlate the phase behaviour of light compounds-containing systems and gas-hydrocarbon systems. Gases considered include H2, CH4, N2, CO2, CO and SH2. An extensive literature search was conducted to obtain the binary experimental vapour-liquid equilibrium data which were used to build a predictive procedure of phase behaviour. Average error in bubble pressure predictions for 812 isothermal data sets (4399 experimental points) is 4%. Calculations with systems containing highly polar substances, water and methanol, are included. Good results are obtained when the proposed method is used to predict phase behaviour of some ternary systems typically encountered in petroleum and related industries.
