This method is able to handle difficult situations such as narrow boiling point regions and phase appearance and disappearance, which are dominant in thermal processes. The formulation and algorithm of the new method are presented in detail. Therefore phase stability analysis is not necessary. The flash calculation method uses a modified Rachford-Rice monotonic objective function and the negative flash concept for phase distribution and phase identification. Development of a robust and fast isenthalpic multiphase flash calculation method is necessary to improve the efficiency of such simulations.ДЄ new isenthalpic multiphase flash calculation is described in this paper.

Development of a robust and fast isenthalpic We describe the numerical approach for solving the tie line intersection equations, and we use slim tube test and compositional simulation data reported in the literature to show that the proposed approach can be used to calculate MMP accurately for displacements with an arbitrary number of components present. The MMP is calculated as the pressure at which one of the key tie lines becomes a critical tie line (a tie line of zero length that is tangent to the critical locus). Besides the tie lines that extend through the initial oil and injection gas compositions, there are nc-3 tie lines, known as crossover tie lines, that can be found from a set of conditions that require the extensions of the appropriate tie lines to intersect each other. The theory shows that in a displacement of an oil by a gas with nc components, the behavior of the displacement is controlled by a sequence of nc-1 key tie lines. Abstract We describe and test a method for calculation of minimum miscibility pressure (MMP) that makes use of an analytical theory for one-dimensional, dispersion-free flow of multicomponent mixtures.
