Karr column, extraction using

Countercurrent columns with additional kinetic energy input have found a broad range of industrial applications [42-48]. Examples of extraction towers with energy input are pulsed towers, pulsed packed columns and pulsed perforated-plate towers. A number of units with some form of mechanical agitation are also used (Karr column, Scheibel column, Oldshue-Rushton column, Ktihni column, RZE extractor, RDC and ARD extractor, Graesser contactor). [Pg.40]

Estimate the diameter and the HETS of a Karr column to extract acetic acid from water using isopropyl ether for the conditions and data of Problem 7.21. [Pg.475]

Solvent extraction systems often display nonlinear equilibrium behavior. Pratt (1983) and Pratt and Stevens (1991) have illustrated methods in which results of sufficient accuracy are obtained by representing the equilibrium curve by means of two or three straight segments for both continuous as well as multicompartment columns. Additional simple and shortcut procedures have been described by Von Stockar and Lu (1991). The extent of backmlxing In the continuous phase in Karr reciprocating-plate extraction columns (Figure 8.1.35(d)), widely used In the petroleum, pharmaceutical and hydro-metallurgical Industries, has been studied experimentally by Stella et al. (2006). [Pg.751]
