a shortcut procedure as quick, easy-to use method for design and simulation of multicomponent batch distillation is used to predict the operating condition of recovering xylene from solvent in an existing batch distillation column in benzol refinery. the procedure can be used to investigate the effect of the operating parameters on the operation of column for three possible modes of batch disti...

In industry, many separation processes involve the separation of multicomponent mixtures using distillation. There are many distillation configurations that can carry out the same overall separation process. These configurations use an equal number of distillation columns, but they differ significantly in energy consumption. Therefore a major challenge for a practitioner is the identification o...

the equation of state soave-redlich-kwong (srk) and its modification (predictive srk or psrk) are applied to simulate multicomponet distillation, which separate main component of spearmint essential oil. the simulation model is based on bubble point method, and the wang-henke algorithm. spearmint essential oil is considered in the study and the original experimental data were obtained from pilo...

The design and optimization of a coupled multicomponent distillation system is a non-linear and multivariable problem. The complexity of this kind of problem results in high solving difficulty. This paper addresses the application of genetic algorithms to the optimization of intensified distillation systems for quaternary distillations. We used a multiobjective genetic algorithm with restrictio...

Abstract Dividing-wall columns(DWC) are intensified distillation systems for multicomponent separations. They have the potential to save both energy and capital costs significantly than conventional simple column configurations. The several DWC columns for ternary distillations have been figured out by some creative activities from different inventors. Recently they have gained the momentum to ...

Packed distillation and absorption columns are often modeled using equilibrium stages. However, determination of the packing height that corresponds to an equilibrium stage is not easy. For binary systems HETP values can be used, but these are not applicable to multicomponent systems because mass transfer rates of different components deviate from each other. Rate-based non-equilibrium models c...
