Optimum Feed Point in Multicomponent Distillation

Multicomponent batch distillation column design

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...

Feed Distillation Using AdaBoost and Topic Maps

This paper retains the experiences by participating in TREC 2007 Blog Track ‘Feed Distillation’. To perform the run various classifiers are combined, which analyze title-, contentand splog-specific features to predict the relevance of a feed related to a topic, based on the idea of AdaBoost. The implemented classifiers utilize keywords retrieved from different thesauri such as Wordnet and Worts...

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...

A simple design method for multicomponent distillation columns

Multicomponent-distillation calculation methods are classified as rating or design methods. A few rating methods are widely used but none of the design methods has found general acceptance. Recently, a few design methods have been proposed using the stage-tostage calculations and starting from one of the ends of the column, but they require tedious calculations. We present here a simple design ...
