Petroleum sorbent pillows are designed with a scrim that encases particulate sorbent material. Pillows are used in areas where more capacity is desired than can easily be achieved using a sorbent pad.3M Marine Oil and Fuel Absorbent Bilge Pillow holds up to two litres of oil. Simply toss the pillow in the bilge and it will soak up oil and gasoline, but repel water. The bilge water can then be pumped overboard legally.
