Abstract
The invention relates to compositions and methods for separating oil and other contaminants (particularly oleophilic compounds) from water and other carriers. The invention is particularly useful for separating oil and other oleophilic compounds from bilgewater and other wastewater. The compositions typically comprise a hydrocarbon resin and a drying oil. The compounds in the composition are typically combined in an organic solvent. For example, hydrocarbon resin and tung oil are optionally combined into a naphtha solvent. The invention is particularly useful for separating emulsified oil from water, whether oil in water emulsions or water in oil emulsions.
Claims4
A method of separating oil contaminant or other oleophilic contaminants from a carrier comprising:
- contacting the oil contaminant or other oleophilic contaminants and carrier with a composition comprising a hydrocarbon resin and a drying oil;
- separating the carrier from the composition, wherein the oil contaminant or other oleophilic contaminants are retained on the composition;
- and
- wherein the carrier is separated from the composition by flowing the carrier under pressure through the composition.
