OHMSETT (Oil and Hazardous Materials Simulated Environmental Test Tank) Tests of TOSCON (Texas Oil Spill Control, Inc.) Weir Skimmer and Gravity Differential Separator

摘要

An evaluation of the effectiveness of the Texas Oil Spill Control, Inc. (TOSCON) weir skimmer and gravity differential separator was conducted at the U.S. Environmental Protection Agency's Oil and Hazardous Materials Simulated Environmental Test Tank (OHMSETT) facility in October 1982. The skimmer was designed to operate at intake rates up to 227 cubic meters per hour (cu m/hr) alone and up to 11.4 cu m/hr when operated with the oil/water separator. Recovery efficiency and oil recovery rate were the criteria used to measure the skimmer's performance with respect to oil slick thickness, propeller speed, waves, and tow speed. Separator performance was judged by its effectiveness in separating an oil and water dispersion with respect to percent water in the oil effluent and oil concentration in the water effluent samples. The independent variables used in testing the separator were flow rate and oil concentration of the influent liquid.
