Absorbent pillow

Apparatus for absorbing liquids including chemical solutions and hydrocarbons on a non-selective basis comprising an expendable pillow, said pillow including a container having a plurality of pockets, each pocket being only partially filled with a granular absorbent organic material capable of absorbing said liquids and expandable on contact with said liquids to fill the remainder of the pockets, said material having a density of not more than fifteen pounds per cubic foot, and said container being a non-woven synthetic fabric coated with a surfactant such that said fabric has a high permeability.

Apparatus in accordance with 7 wherein said pillow has a weight of not more than about four pounds.

A method of cleaning up an environmental problem involving a spillage of hydrocarbons comprising the steps of contacting the hydrocarbons with an expendable pillow made from a non-woven synthetic fabric of high permeability and having a plurality of pockets each partially filled wih granular absorbent material having an absorption capacity in excess of 300% and a density of about fourteen pounds per cubic foot, said material including corncob granules free of dust, expanding said material as it absorbs hydrocarbons which pass through said fabric and causes said material to fill the pockets, and then disposing of the pillow.

A method of cleaning up an environmental problem involving a spillage of liquids comprising the steps of contacting the liquid spillage with a floatable pillow made from a non-woven synthetic fabric of high permeability, providing said pillow with a plurality of discrete pockets each only partially filled with granular corn cob material having an absorption capacity in excess of 300 percent and a density of about fourteen pounds per cubic foot, expanding said material as it absorbs liquid spillage which passes through said fabric and causes said material to fill the pillow pockets, then disposing of the pillow in a non-polluting manner.

Apparatus for absorbing liquids from a surface which constitute an environmental problem comprising an expendable pillow, said pillow being in the form of a container having a plurality of pockets being only partially filled with an organic granular absorbent material occupying not more than about 50% of the volume of each pocket, two pockets being separated by stitching, said stitching including a circular area lacking said granular absorbent material and with the fabric being slit within the circular area so that the pillow may circumscribe an annular conduit adapted to extend through the circular area, said container being made from a non-woven synthetic fiber, said container being coated with a surfactant such that said container has a high permeability, said granular material having an absorption capacity in excess of 300% so that it may expand on contact with liquids and fill the pockets, the weight of the pillow before use being less than four pounds.
