Abstract
A bag, particularly adapted for absorbing hydrocarbons dispersed in smaller quantities of water, has a ball-like shaped body formed from oleophobic netting materials. The bag body includes a tubular-shaped outer sleeve positioned about a tubular-shaped inner sleeve to form an interior space therebetween. Adjacent end portions of each sleeve then are connected so that an absorbent medium in the bag interior space is fully enclosed. The inner sleeve defines a central passageway through the bag. To hold the bag during use, a cord loop may be disposed in the central passageway with a knotted end of the cord joined with one of the sleeve end portion connections. A looped end of the cord then extends from an opposite end of the central passageway to provide convenient means for attaching the bag to a support while the bag is immersed in a hydrocarbon-water mix. As hydrocarbons are drawn to strands of the bag netting and then collect in voids of the netting, the bag discolors. When sufficiently discolored, the bag is withdrawn for external cleaning or disposal.
