چکیده

The minimum energy requirements of six different heat-integrated multi-effect and three non-integrated distillation arrangements for separating a ternary mixture have been considered. The focus of the paper is on a heat-integrated complex distillation configuration; called a multi-effect prefractionator arrangement. The comparison of the different arrangements is based on the minimum vapour flowrates at infinite number of stages, which are easily visualised and compared in a Vmin-diagram. This tool can be used as a basis for screening and the best arrangement(s) can be studied further using more rigorous simulation methods.

Minimum Energy and Entropy Requirements in Multicomponent Distillation

We present new analytical expressions for minimum energy consumption (1 law) and minimum entropy production, or lost work (2 law), in complex distillation arrangements. These simple, but exact, expressions apply to ideal mixtures and an infinite number of stages, and the relative volatility is the only required component property. The simple Vmin-diagram is shown to be very useful in evaluating...

Minimum Energy Consumption in Multicomponent Distillation. 3. More Than Three Products and Generalized Petlyuk Arrangements

We consider separation of ideal multicomponent mixtures with constant relative volatilities and constant molar flows and at constant pressure. The exact analytical solution of minimum energy in a generalized Petlyuk arrangement for separation of N-component feed into M products has been derived. Interestingly, the minimum-energy solution in a complex integrated Petlyuk arrangement is equal to t...

Energy and Economic Optimization of Distillation Sequencing

Effective parameters that can effect on the performance of the separation system consist of operating pressure, operating temperature, reflux ratio, and kind of produce desirable products and different sequences of splits. As take a separation system with optimal performance is dependent on optimization of above mentioned effective parameters. In generally, there are two criteria (as object fun...

Economic Optimization of the Reflux Ratio of Two Components Stage Distillation Columns

Distillation columns are complex processes for modeling and controlling. These columns are significant parts of most chemical industries for separation of components. Control of this process is essential for achieving certain purity for products with a minimum cost. However, nonlinearities, multivariable interaction, non-stationary behavior and severity of disturbances inside the column made th...
