根据Patel-Teja状态方程(具有与密度无关的混合准则)的Valderrama改进方程及Debye-Hückel静电学条件建立了一个模型,通过校正水相的介电常数、密度和相对分子质量等性质,可应用于含盐和化学抑制剂系统中。通过在介电常数混合准则中引入一个反应参数来确定无盐混合物中的介电常数,使用含盐和有机抑制剂的水溶液的凝固点数据进行校正。在有盐和有机抑制剂的情况下,通过使用水蒸汽压力数据来调整盐和有机抑制剂之间的双元反应参数。对预测值和实验数据、参考文献中模型的数据所进行的比较证明了该模型的可靠性。
A model is established based on the Valderrama equation and the Debye-Hückel equation for the Patel-Teja equation of state (mixing criteria independent of density). By calibrating the dielectric constant, density and relative molecular mass of the aqueous phase, In salt and chemical inhibitor systems. The dielectric constant in the salt-free mixture is determined by introducing a reaction parameter in the dielectric constant mixing guideline, which is corrected using the freezing point data of the aqueous solution containing the salt and the organic inhibitor. In the presence of salts and organic inhibitors, the binary reaction parameters between salt and organic inhibitor are adjusted by using water vapor pressure data. The comparison between the predicted value and the experimental data and the data in the reference model proves the reliability of the model.
