Computer control of holdup in a reciprocating plate extraction column

Abstract This paper describes the application of computer control to a pilot scale (15 cm diameter) Reciprocating Plate Solvent Extraction Column. The system under investigation was kerosene dispersed in water without mass transfer between the phases. The control objective was the regulation and set point tracking of the holdup of the dispersed phase. Dynamic tests showed that the column was a non‐minimum phase, dead‐time process with …
