Project description:Specification of prediction of two-phase multi-component vapor-liquid and liquid-liquid equilibria by using of binary and ternary equilibrium data. Extension of the method of correlation of three-component equilibrium data of two-phase systems (vapor-liquid and liquid-liquid) by the universal ternary contribution. Investigation of the influence of the ternary correction evaluated from ternary vapor-liquid equilibrium data and combined vapor-liquid and liquid-liquid data for obtaining more precise prediction of a complex two-phase four-component equilibrium. Application of the calculation for systems related to the separation of BTX aromatics with mixed extraction solvents. Modeling of a column for separation of model mixture alkane ? aromatic hydrocarbon in a presence of extractive solvent using original GE equation model parameters. Simulation of a Residue curve map of chosen mixture and investigation of the region of components partial miscibility and its influence on the separation efficiency of distillation column.
