Abstract
The extraction of phenol from aqueous solution was studied in a novel type of device—a hollow fiber “shell and tube bundle” unit. The need for coalescence and settling of the two phases involved is avoided with this type of contacting scheme. Various solvents (n-hexanol, n-octanol, ii-decanol, methyl isobutyl ketone, and n-butyl acetate) were used on the shell-side; the phenol solution was pumped through the tube-side. In other runs, powdered activated carbon was packed into the shell-side. The effects of solvent type, powdered carbon use, feed stream flow rate, and the addition of acid or base to the feed were studied. A successful mathematical model for the system was developed.
