A Feasibility Study of the Use of the Oleophilic Belt Oil Scrubber

摘要

The paper is the result of an integrated program of mathematical modeling and experimentation undertaken to develop an understanding of the oleophilic belt 'Oil Scrubber' concept which would allow prediction of the performance of proposed large scale prototype devices. The parameters which govern the maximum oil recovery rates possible with such devices are identified, and their relative importance established. It is concluded that the maximum oil recovery rate of an oleophilic belt oil scrubber is generally limited by the rate at which oil can be transferred from the water surface to the belt surface and interior. Further, the 'Oil Scrubber's' performance is not detrimentally affected by the action of waves or limited presence of solid materials. The stability of the belt in a transverse flow is identified as a primary concern for operations in the presence of currents. Data are presented in a dimensionless form which facilitates the prediction of the performance of large devices of various belt geometries. It is shown that a single large belt is not a practical means of cleaning up large thin slicks in a short period of time. The feasibility study has not uncovered any technological constraints that would prevent operation of a prototype oleophilic belt system at the target environmental conditions. (Author)
