摘要：用TRK状态方程,采用可调的振荡参数,对48个二元系进行了相平衡关联,并将其准确度分别与a)修正的SRK方程,b)基于对应状态原理的SRK方程及c)利用Huron-Vidal局部组成混合规则的SRK方程相比较。结果发现:TRK方程用了本文改进的计算方法后不仅能加快运算速度,避免发散,且能适用于更多类型的二元系相平衡数据关联;k_(12)(?)k_(21)时的TRK方程与a)、b)、c)相比,占明显优势。
Based on TRK equation of state with adjustable cscillaticn control parameter,phase equilibrium data of 48 binary ststems were correlated. The results are compared with those obtained respectively by, (a) modified SRK equation of state, (b) the SRK equation of state deduced from corresponding state principle, and (c) the SRK equation of stale based on Huron-Vidal local composition mixing rule. It shows that the modification of calculation method, i.e. introducing an adjustable oscillation control parameter for the TRK equation of state, not only speeds up the calculation, but also avoids divergence. In addition. The method exhibits superion performance over others mentioned above in the case of k_(12)≠k_(21).
