Mass transfer and pressure drop in a cocurrent reciprocating plate extraction column

Abstract A 5‐cm‐diameter reciprocating plate extraction column has been operated in cocurrent flow. The pressure drop for water flow, and the local and average mass transfer products for the system acetic acid/kerosene/aqueous sodium hydroxide have been measured. Under well‐agitated conditions, the mass average transfer product is predictable by a model, which is also applicable to data reported earlier by Karr for a 2.54‐cm‐diameter column.
