Abstract:
1. A method for removing water from an organic liquid, the method comprising the step of: (A) contacting a water-containing organic liquid with at least one filtration medium designed to remove all or substantially all of the water present in the organic liquid; and (B) removing substantially all of the water from the organic liquid to yield a water-free organic liquid, wherein the at least one filtration medium is formed from at least one absorbent fibrous component and at least one hydrophilic elastomeric fibrous component, wherein the absorbent fibrous component is selected from polyesters, polyethers, polyester-polyethers, polymers having pendant carboxylic acids or pendant hydroxyls, polysiloxanes polyacrylamides, kaolins, serpentines, smectites, glauconite, chlorites, vermiculites, attapulgite, sepiolite, allophone and imogolite, sodium polyacrylates, 2-propenamide-co-2-propenoic acid, or any combination of two or more thereof, wherein the hydrophilic elastomeric fibrous component is selected from zein protein, polyester elastomers, polydimethylsiloxane, hydrophilic poly(ether-co-ester) elastomers, silicone-co-polyethyleneglycol elastomers, polyacrylates, thermoplastic polyurethanes, poly(ether-co-urethanes), or any combination of two or more thereof, wherein the absorbent fibrous component is embedded in the hydrophilic elastomeric fibrous component, and wherein the at least one absorbent fibrous component and the at least one hydrophilic elastomeric fibrous component differ from one another and the at least one absorbent fibrous component is more absorbent than the at least one hydrophilic elastomeric fibrous component.
