WebMar 21, 2011 · Using the developed method, we obtain satisfactory results that are quantified by the following statistical parameters: absolute average deviations of the … WebIn order to model the IFT, CPA was coupled with the parachor method and the lindar gradient theory. The density predictions are generally satisfactory although the calculated liquid and vapor densities have some non-negligible deviations. It shows a large deviation for the high-pressure IFT although the low-pressure IFT is reasonably described.
