Traditionally polyester production is done in a batch reactor equipped with a separation column for batch distillation. A promising alternative for the intensification of this process is reactive distillation. In this paper, a reactive distillation model is developed for the synthesis of an unsaturated polyester process. The simulation results are compared with the industrial batch reactor outp...

Previous studies have revealed it is possible to separate a high-boiling mixture by gas chromatography in empty fused-silica capillary tubing rather than in columns coated with stationary phase. Chromatographic separation occurs solely on the basis of the different boiling points of the substances separated. The high similarity of such separations to those in classic distillation seems advantag...

Techniques such as ensembling and distillation promise model quality improvements when paired with almost any base model. However, due to increased testtime cost (for ensembles) and increased complexity of the training pipeline (for distillation), these techniques are challenging to use in industrial settings. In this paper we explore a variant of distillation which is relatively straightforwar...

The TREC 2003 web track consisted of both a non-interactive stream and an interactive stream. Both streams worked with the .GOV test collection. The non-interactive stream continued an investigation into the importance of homepages in Web ranking, via both a Topic Distillation task and a Navigational task. In the topic distillation task, systems were expected to return a list of the homepages o...

The essential oils are frequently used in food processing industry, perfumery, cosmetics and pharmaceuticals. Most of the oils obtained by steam distillation and water distillation. It is necessary to specify the best conditions of essential oils production to get much more major compound(s) and higher yield oil. So, fennel oil was selected in this study. The objective of this work was to ident...

Milk fats from different species of mammals are known to vary considerably in chemical composition. In early work, the butter fat constants were largely used to indicate the differences in composition. More recently, emphasis has been placed on comparisons of the component fatty acids of the various types of butter fats. The methods available for separation of the acids are not conducive to hig...

The paper discusses distillation column control within the general framework of plantwide control. In addition, it aims at providing simple recommendations to assist the engineer in designing control systems for distillation columns. The standard LV-configuration for level control combined with a fast temperature loop is recommended for most columns.

Batch distillation is an important separation process for small-scale production especially in pharmaceutical, specialty chemical and biochemical industries. Although batch distillation units require lower capital cost than continuous units, the unsteady state nature of the process, results in higher operating costs. Optimal control in batch distillation is a mode of operation which allows us t...

The understanding of the dynamic behavior of distillation columns has received considerable attention due to the fact that distillation is one of the ost widely used unit operations in chemical process industries. Thermally coupled distillation sequences (TCDS) can provide significant energy avings with respect to the operation of sequences based on conventional distillation columns. TCDS exhib...
