Abstract
Abstract A pillow for placement in enclosed areas utilized to collect and contain spilled or leaked hydrocarbons such as boat bilges and sumps absorbs pollutants that come in contact. The absorbed material is solidified within the pillow into a rubber-like mass. The consolidated mass will float indefinitely and is easily retrieved and handled for disposal. The pillow will not leech solidified hydrocarbons when exposed to pressure limits used to determine landfill suitability.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
92 words
A hydrocarbon absorbent device comprising: an outer envelope layer of textile material; a plurality of stacked layers of textile material disposed within the envelope and forming a plurality of enveloping chambers in stratification; an organic elastomer polymer material having the ability to absorb and solidify liquid hydrocarbons being disposed in and between each of the chambers; a seam joinder of the envelope and stacked layers, wherein said plurality of stacked textile layers dispersively conduct liquid hydrocarbons under capillary attraction throughout the interior of said envelope for absorption and solidification by said polymer.
Claim 2
Dependent Claim
