Abstract
A method and apparatus are provided for removing oil from absorbent materials of the type used in components for absorbing oil and containing oil spills. The components are first passed through a press to squeeze some of the oil from the components. The components are then shredded to separate the components into separate pieces of the absorbent materials. An auger pushes the pieces of absorbent materials into an elongated tubular trommel having a perforated sidewall. The pieces of absorbent materials are sprayed with treatment fluids as the trommel is rotated to tumble the absorbent materials within the trommel. The oil and treatment fluids drain from the absorbent materials, and pass through the perforations in the trommel sidewalls and onto a collection trough. The collection trough directs the oil and treatment fluids through a separator to reclaim treatment fluids and oil for later use. The absorbent materials within the trommel continue to be tumbled as they pass through a drying section in which hot air from a furnace is blown through the pieces of the absorbent materials. The absorbent materials then pass to a repacking section where they are repackaged into components for use in absorbing oil and containing oil spills.
