Method For Treating Oil

摘要

A method for treating an oil spill includes providing a polystyrene-based sorbent in the form of polystyrene microfibers having a sorption capacity in the range of between 30 g/g to 217 g/g, measured as grams of oil sorbed per one gram of the sorbent; drenching the polystyrene microfibers in the oil spill to be treated; collecting the oil drenched polystyrene microfibers; and removing excess oil from the oil drenched polystyrene microfibers by compressing the microfibers. The method further includes dissolving the oil drenched polystyrene microfibers in a petroleum-based solvent in the form of gasoline having an octane number of ninety one, in which both the oil drenched polystyrene microfibers and the oil is soluble, thereby forming a solution comprising the gasoline having dissolved therein the polystyrene microfibers and the oil; and utilising the solution as a feedstock for feeding a refinery.
