EXPERIMENTAL EVALUATION OF FIBROUS BED COALESCERS FOR SEPARATING OIL-WATER EMULSIONS

A laboratory scale oil-water coalescer bed was formed from standard, phenol formaldehyde coated fiber glass, consisting of 3 layers. The bed was then compressed between screens to an overall thickness of 1/4 inch, giving an apparent overall density to the working membrane of 10.8 lb/cu ft. By testing the cell on a synthetic oil dispersion and an actual pollutant stream, a 100% coalescence efficiency at a 7.5 gpm flow rate over the entire run time was established. Stabilization of fibers to mechanical degradation was accomplished by coating the compressed fibers with isobutyl methacrylate resin. This medium, showing the same coalescence efficiency and pressure drop characteristics for the original medium, was regenerable by solvent treatment. Operating costs based on single use of fibers were estimated.
