Abstract
ABSTRACT Analyses and experimentation have indicated that the maximum recovery rate of an oleophilic belt oil recovery system is generally limited by the rate at which oil may be transferred to the belt surface and interior. The rate of absorption of oil by an oleophilic belt increases with increasing specific surface and permeability of the belt material increasing slick depth, decreasing oil viscosity, and decreasing interfacial tension between the oil and belt material. In operations with high viscosity oils and high belt speeds significant quantities of oil may be withdrawn on the belt's outer surface. The oil scrubber's performance is not detrimentally affected by the presence of waves, nor by the presence of solid materials, emulsions, or “rag” in limited quantities. The stability of the belt is a primary concern for operations in the presence of transverse currents.
