Global optimization of multicomponent distillation configurations: Global minimization of total cost for multicomponent mixture separations

Multicomponent Distillation Configurations with Large Energy Savings

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...

Modeling of Spiral-Wound Permeators for Multicomponent Gas Separations

Two multicomponent models for spiral-wound gas permeators are proposed. The basic transport model is derived from fundamental material balances and permeation relations that account for permeate-side pressure variations. The resulting model consists of a set of nonlinear differential-algebraic-integral equations with mixed boundary conditions, as well as an implicit expression for the local fee...

New Method for Designing Distillation Columns of Multicomponent Mixtures

This paper presents a series of calculation procedures for computer design of ternary distillation columns overcoming the iterative equilibrium calculations necessary in these kind of problems and, thus, reducing the calculation time. The proposed procedures include interpolation and intersection methods to solve the equilibrium equations and the mass and energy balances. The calculation progra...

Magnetohydrodynamics for a multicomponent ionic mixture

The magnetohydrodynamical equations for a multi-component magnetized ionic mixture are used to derive the spectrum of collective modes for small wave numbers. The results are compared with those from formal kinetic theory, which is based on the microscopic balance equations and a projection-operator formalism. The comparison leads to a set of Green–Kubo-type expressions for the phenomenological...
