РЕФЕРАТ (Abstract)

The present invention relates to methods for preventing and/or reducing the occurrence of corrosion in a variety of articles including, but not limited to, tanks (e.g., storage tanks, septic tanks, fuel tanks, etc.); containers (e.g., shipping containers, storage containers, etc.); semi-closed systems (e.g., fuel systems, septic systems, reservoirs, etc.); and/or closed systems (e.g., waste disposal systems, waste disposal drums or containers, etc.). In another embodiment, the methods of the present invention may be utilized to reduce and/or prevent corrosion in a variety of pipelines (e.g., gas/oil pipelines, water pipelines, sewage lines, etc.). More specifically, the present invention relates to methods for preventing and/or reducing the occurrence of corrosion in a variety of articles including, but not limited to, metallic tanks; metallic containers; pipelines; semi-closed systems; and/or closed systems which are constructed partially or totally from metal. (e.g., steel, iron, copper, brass, aluminum, etc.).

ФОРМУЛА ИЗОБРЕТЕНИЯ (CLAIMS)

What is claimed is:

1. A method for protecting a tank, container, pipeline, semi-closed system or closed system comprising the steps of: (A) placing a corrosion inhibiting device completely into the interior of a tank, container, pipeline, semi-closed system or closed system, wherein the corrosion inhibiting device comprises: a capsule having at least one sealable enclosure therein; at least one corrosion inhibitor, wherein the at least one corrosion inhibitor is contained in the sealable enclosure; and at least one means for delivering the at least one corrosion inhibitor from the at least one sealable enclosure of the capsule to an environment external to the at least one sealable enclosure, wherein the capsule is formed from a non-degradable material; and (B) closing or sealing the tank, container, pipeline, semi-closed system or closed system, wherein the at least one means for delivering the at least one corrosion inhibitor from the at least one sealable enclosure of the capsule to an environment external to the at least one sealable enclosure is a degradable plug or cap, wherein the degradable plug or cap is formed from a degradable polymer composition.

2. A method for protecting a tank, container, pipeline, semi-closed system or closed system comprising the steps of: (A) placing a vapor phase corrosion inhibiting device into the interior of a tank, container, pipeline, semi-closed system or closed system, wherein the corrosion inhibiting device comprises: a capsule having at least one sealable enclosure therein, wherein the capsule is formed from a non-degradable material; at least one degradable layer which contains therein at least one vapor phase corrosion inhibitor which is formed within the at least one sealable enclosure of the capsule; and at least one degradable layer which contains no vapor phase corrosion inhibitor which is formed within the at least one sealable enclosure of the capsule, wherein the at least one degradable layer which contains at least one vapor phase corrosion inhibitor and the at least one degradable layer which contains no vapor phase corrosion inhibitor are formed in alternating layers with the proviso that at least one degradable layer which contains no vapor phase corrosion inhibitor is the outer most layer within the at least one sealable enclosure of the capsule; and (B) closing or sealing the tank, container, pipeline, semi-closed system or closed system.

3. The method of claim 2, wherein the non-degradable material is formed from a non-degradable or corrosion resistant metal.

4. The method of claim 3, wherein the metal is selected from aluminum, stainless steel or steel.

5. The method of claim 2, wherein the non-degradable material is formed from a non-degradable or corrosion resistant polymer composition.

6. The method of claim 5, wherein the polymer composition is a polyolefin polymer composition.

7. The method of claim 2, wherein the corrosion inhibiting device is contained within the cover or cap of a tank.

8. A method for protecting a tank, container, pipeline, semi-closed system or closed system comprising the steps of: (A) placing a vapor phase corrosion inhibiting device into the interior of a tank, container, pipeline, semi-closed system or closed system, wherein the vapor phase corrosion inhibiting device comprises a self-contained vapor phase corrosion inhibiting capsule, wherein the self-contained vapor phase corrosion inhibiting capsule is capable of being inserted into a tank, container, pipeline, semi-closed system or closed system without adversely affecting same, the self-contained vapor phase corrosion inhibiting capsule comprising: at least one degradable layer which contains therein at least one vapor phase corrosion inhibitor; and at least one degradable layer which contains no vapor phase corrosion inhibitor, wherein the at least one degradable layer which contains at least one vapor phase corrosion inhibitor and the at least one degradable layer which contains no vapor phase corrosion inhibitor are formed in alternating layers with the proviso that at least one degradable layer which contains no vapor phase corrosion inhibitor is the outer most layer within the self-contained corrosion inhibiting capsule; and (B) closing or sealing the tank, container, pipeline, semi-closed system or closed system.

9. The method of claim 2, wherein the at least one degradable layer that contains therein at least one vapor phase corrosion inhibitor is formed from a biodegradable polymer.

10. The method of claim 2, wherein the at least one degradable layer that contains no vapor phase corrosion inhibitor is formed from a biodegradable polymer.

11. The method of claim 8, wherein the at least one degradable layer that contains therein at least one vapor phase corrosion inhibitor is formed from a biodegradable polymer.

12. The method of claim 8, wherein the at least one degradable layer that contains no vapor phase corrosion inhibitor is formed from a biodegradable polymer.
