Design and optimization procedures employing the response surface methodology (RSM)
for retrofitting the conventional extractive distillation sequence to a thermally coupled …

We describe a new configuration for falling film distillation columns: a heating system
provided by a vapor chamber along the entire column with the operation at atmospheric …

Dividing wall columns, capable of reducing the energy required for the separation of ternary
mixtures, were explored for the energy-efficient integration of debutanization and …

A side distillation column is widely used to separate multicomponent mixtures into three
products. However, this kind of column consumes considerable amounts of energy due to …

A dividing-wall prefractionator configuration was investigated for a safe and economic retrofit
of the conventional sequence using simple distillation columns. In the proposed retrofit …

Methanol in crude glycerol from biodiesel production is considered to be a raw material for
dimethyl ether production. In this work, the production of dimethyl ether from the dehydration …

Separation of azeotropic mixtures is one of the most energy intensive systems in
petrochemical industries. In the present study effect of feed-splitting on energy demand of …

The objective of many studies in this area has involved access to a column-sequencing
algorithm enabling designers and researchers alike to generate a wide range of sequences …

In this work, a distillation system is designed to purify dimethyl ether (DME) from its reaction
by-products in the conversion of flare gas into a useful energy product. The distillation …
