Control of Vapor Recompression Distillation Columns

Parametric study of an ethanol–water distillation column with direct vapour recompression heat pump

“…The pressure drop over the entire distillation column is caused by losses due to vapour flowing through the connecting pipes and through pressure drop over the stages in rectifying and stripping section. Constant pressure drop per tray have been estimated from several authors to be equal to 5.3 mm Hg per tray (Meili and Stuecheli, 1987;Muhrer et al, 1990). The total column pressure drop has been found by summing plate pressure drops ΔP cl ΔP cl = 0:13332 × 5:3 × N = 0:707N:…”

Heat integrated distillation operation

“…There has been additional work in control using classical controllers and experimental equipments reported in literature (e.g. [68][69][70][71][72][73]). …”
