Hydraulic Design of Thermally Coupled Columns and a DWC for NGL Fractionation Plants
Combining a conventional demethanizer with thermally coupled deethanizer and propane-butane recovery columns or a three-product dividing wall column (DWC) provides a realistic opportunity for natural gas liquids (NGL) fractionation complexes as encountered in floating, as well as on-land natural gas...
On controllability of four-product dividing wall columns
Although potential for reduction of energy requirement and related carbon dioxide emissions is highly attractive – around 50% compared to conventional three column sequences – process industries are still reluctant to consider implementation of four products fully thermally coupled dividing wall col...
Dividing wall columns for natural gas liquefaction plants
In order to meet current carbon dioxide emissions reduction challenges, natural gas processing and refining industries have to find the ways to minimize energy requirements of distillation operations. Building on foundations lied down in a preceding effort, this paper shows that this could be achiev...
