Materials and Methods for Removing Oil from Bodies of Water
Strong fabrics with an affinity for oil can be deployed from boats and other sea vessels to absorb oil that has been spilled into oceans, gulfs, rivers, or other bodies of water. For example, strong nylon spunbonded fabrics can be used to soak up oil from bodies of water. The fabrics can also be used in concert with other methods, such as with containment booms.
1 . A method for recovering oil from a body of water, comprising:
deploying a fabric into the body of water;
allowing the fabric to absorb oil from the body of water; and
recovering the fabric from the body of water after the fabric has absorbed oil from the body of water.
2 . The method according to claim 1 , wherein the oil absorbed by the fabric is crude oil.
3 . The method according to claim 1 , wherein allowing the fabric to absorb oil from the body of water comprises allowing the fabric to absorb oil from the body of water until the fabric is saturated with oil.
4 . The method according to claim 1 , wherein the fabric is a nylon fabric or a polyester fabric.
5 . The method according to claim 1 , wherein the fabric is a nylon nonwoven fabric.
6 . The method according to claim 5 , wherein the oil absorbed by the fabric is crude oil.
7 . The method according to claim 5 , wherein allowing the fabric to absorb oil from the body of water comprises allowing the fabric to absorb oil from the body of water until the fabric is saturated with oil.
8 . The method according to claim 6 , wherein allowing the fabric to absorb oil from the body of water comprises allowing the fabric to absorb oil from the body of water until the fabric is saturated with oil.
9 . A method for removing oil from a body of water wherein said method comprises deploying, from a vessel, a fabric into the body of water, moving the vessel through the water such that the fabric is pulled behind the vessel thereby contacting and absorbing oil in the water, and removing the fabric, with the absorbed oil, from the water.
10 . The method, according to claim 9 , wherein the vessels are boats.
11 . The method, according to claim 9 , wherein the fabric is weighted such that it is pulled at or below the surface of the water.
12 . The method, according to claim 9 , wherein the body of water is selected from oceans, seas, lakes, gulfs, and rivers.
13 . The method, according to claim 9 , wherein the surface area of the fabric is at least 100 square yards.
14 . The method, according to claim 9 , wherein the method further comprises removing from the fabric oil that has been absorbed by the fabric.
15 . The method, according to claim 14 , wherein said removal of oil comprises physical, chemical, and/or biological treatment of the fabric.
16 . The method, according to claim 15 , which comprises removing oil by passing the fabric between rollers.
17 . The method, according to claim 9 , which comprises re-using the fabric to remove more oil from the body of water.
18 . A vessel adapted to deploy fabric into a body of water, and to retrieve the fabric.
19 . A method for removing oil from a body of water wherein said method comprises deploying, from one or more vessels, a fabric into the body of water, moving one or more vessels through the water such that the fabric is pulled behind one or more vessels thereby contacting and absorbing oil in the water, and removing the fabric, with the absorbed oil, from the water by another vessel that did not originally deploy the fabric.
20 . The method, according to claim 19 , wherein the vessels are boats.
21 . The method, according to claim 19 , wherein the fabric is weighted such that it is pulled at or below the surface of the water.
22 . The method, according to claim 19 , wherein the body of water is selected from oceans, seas, lakes, gulfs, and rivers.
23 . The method, according to claim 19 , wherein the surface area of the fabric is at least 100 square yards.
24 . The method, according to claim 19 , wherein the method further comprises removing from the fabric oil that has been absorbed by the fabric.
25 . The method, according to claim 24 , wherein said removal of oil comprises physical, chemical, and/or biological treatment of the fabric.
26 . The method, according to claim 25 , which comprises removing oil by passing the fabric between rollers.
27 . The method, according to claim 19 , which comprises re-using the fabric to remove more oil from the body of water.
