Abstract

The invention relates to a substance produced, typically, from the cork of the cork-tree (Quercus Suber) by subjecting it to physical and chemical treatment to render it oleophilic and hydrophobic. Such a substance is reduced in size to give it optimum sorption capacity. The substance is used either as a loose powder, or contained in an oil-permeable packaging in the shape of a pillow, sock or blanket. Oil is removed from the surface of water or other substrates by sorption on the substance and can be subsequently recovered by pressure or centrifugal force or by solvent extraction and/or distillation. Alternatively the oil can be incinerated in situ or after removal. Oil can also be recovered from sand and/or shale deposits using the substance.

Description

SPECIFICATION This invention relates to a substance for the sorption of oil and related compounds spilled onto water and other substances A number of mineral, vegetable and synthetic products exist for the treatment of oil spillages on water and other surfaces. To be effective such substances need to be hydrophobic and oleophilic; they vary in their selectivity and capacity to adsorb and/or absorb oil and similar compounds. Few have the additional property of buoyancy and ease of removal from the substrate, together with subsequent recovery of the oil.
The present invention relates to a substance which in its natural form has godd hydrophobic qualities but extremely poor oleophilic character, but which by physical and/or chemical modification achieves the required oleophilic character and oil sorption capacity necessary for the applications described.
Typically the substance consists of the cork of the cork-tree (Quercus Suber.) which has been modified physically and chemically by the application of heat and pressure over a period of time. The product is comminuted to a size range (below Smm mesh) to give optimum oil sorption capacity. The capacity ranges from 5 to 10 fold, in terms of weight of oil or related product to weight of olephilic substance, this compares to 1 to 2 fold for natural cork.
The advantage of the substance which is the subject of the invention over other similar materials, is the ease by which the sorbed oil is collected and separated from water using a strainer of nominal mesh size, affecting 100% recovery with little uptake of water.
Further oil and related compounds can be separated from the sorbate by the application of pressure or centrifugal force, or, alternatively, by solvent extraction and/or distillation.
Disposal of oil and related compounds using the substance which is the subject of the invention, can be achieved by incineration of the sorbate even on the surface of water, when the substance acts as an effective wick whose flame is not quenched by the water present. The environmental impact of the substance is minimal, it being biodegradeable in the field of use, there is also an unlimited resource of raw material.
Further, the packaging of the substance in an oil-permeable material facilitates the application, removal and recovery of oil and related compounds, such packaging can be in the shape of a pillow, a sock or a blanket.
The substance is effective in the removal of oil and related compounds from sand and/or shale, by intimately mixing the substance with the oil bearing sand and separating the components by the addition of water. Again the oil can be recovered by the methods previously described.
1. A substance for the recovery of oil and similar compounds from the surface of water and other substrates.
2. The substance in Claim 1, produced from a natural occuring arborial material, typically the cork of the cork-tree (Quercus Suber.).
3. The substance in Claim 1 and Claim 2, subjected to a process to improve the sorptive character of the raw material, by heating under pressurefor a time.
4. The substance described in Claim 1 and Claim 2, subjected to a chemical treatment to improve the sorptive character of the raw material.
5. A substance as described in Claim 1, Claim 2, Claim 3 and Claim 4, comminuted in size below 5 mm mesh to give a sorptive capacity for oil and related compounds of between 5 and 10 times its own weight.
6. A substance described in Claim 1, Claim 2, Claim 3, Claim 4 and Claim 5, whereby oil and related compounds can be recovered by separation using mechanical means of pressure or centrifugal force.
7. A substance described in Claim 1, Claim 2, Claim 3, Claim 4 and Claim 5, wherby oil and related compounds can be recovered by separation using solvent extraction and/or distillation.
8. A substance described in Claim 1, Claim 2, Claim 3, Claim 4 and Claim 5 whereby oil and related compounds can be incinerated either in situ or after removal from the substrate.
9. A substance described in Claim 1, Claim 2, Claim 3, Claim 4 and Claim 5, packaged in an oil-permeable material in the form of a pillow, a sock or a blanket to allow for recovery according to Claim 6, Claim 7 and Claim 8.
10. A substance described in Claim 1, Claim 2, Claim 3, Claim 4 and Claim 5, used in the removal of oil and related compounds speciifically from sand and/or shale, by intimate mixing and subsequent recovery and separation as described in Claim 6, Claim 7 and Claim 8.
