REMOVAL OF OIL FROM SEAWATER

The report presents a summary and discussion of the results of a test program for separating Bunker C fuel oil and ballast seawater. Mixtures of Bunker C oil and seawater were found to be separable before dispersion by pumping. Enlargement of filter shell and minor modifications to baffles and inlet increased separation efficiency and capacity by a factor of three. Tests on oils of different density indicated oils heavier than seawater could also be separated. A difference in density is an important factor for oil removal but an oil of specific gravity 1.00 was separated at reduced capacity. Automatic operation can be provided by available capacitance probes locating interfaces. Closed-loop control of filter differential pressure can prevent breakthrough in spite of large increases in oil concentration. The test range covered from 0.1 percent to 10 percent oil, and the test temperature was 85 F. Temperature and cleaning rate were not critical factors, flow rate and oil concentration combine to determine the differential drop through the separator. (Author)
