A method for contacting a liquid with a gas in which the gas is introduced into a vessel containing at least one hollow fiber membrane having a plurality of porous hollow fibers. The liquid is introduced into a lumen of at least a portion of the plurality of porous hollow fibers at a liquid pressure

A method for contacting a liquid with a gas in which the gas is introduced into a vessel containing at least one hollow fiber membrane having a plurality of porous hollow fibers. The liquid is introduced into a lumen of at least a portion of the plurality of porous hollow fibers at a liquid pressure sufficient to overcome a resistance to wetting of the porous hollow fibers, thereby covering at least a portion of an outer surface of the plurality of porous hollow fibers with the liquid and providing intimate contact between the gas and the liquid.

We claim: 1. A method for contacting a liquid with a gas comprising the steps of: introducing said gas into a vessel containing at least one hollow fiber membrane comprising a plurality of porous hollow fibers; and introducing said liquid into a lumen of at least a portion of said plurality of porous hollow fibers at a liquid pressure sufficient to overcome a resistance to wetting of said porous hollow fiber, thereby covering at least a portion of an outer surface of said plurality of porous hollow fibers with said liquid, resulting in contact between said gas and said liquid and penetration of a portion of said liquid into said gas. 2. A method in accordance with claim 1, wherein said liquid comprises at least one solvent and said gas comprises at least one component capable of reacting with, or being soluble in, said at least one solvent. 3. A method in accordance with claim 2, wherein said at least one component is hydrogen sulfide. 4. A method in accordance with claim 3, wherein said gas comprises between about 0 ppmv and about 1000 ppmv of said hydrogen sulfide. 5. A method in accordance with claim 3, wherein said gas comprises between about 0 ppmv and about 200 ppmv of said hydrogen sulfide. 6. A method in accordance with claim 5, wherein said gas comprises at least 4 ppmv of said hydrogen sulfide. 7. A method in accordance with claim 1, wherein said hollow fiber membrane is an expanded polytetrafluoroethylene ribbon membrane. 8. A method in accordance with claim 1, wherein said hollow fiber membrane is one of an inorganic membrane and a ceramic membrane. 9. A method in accordance with claim 1, wherein said gas is a mixture comprising natural gas and hydrogen sulfide. 10. A method in accordance with claim 1, wherein said gas is introduced into said vessel at a gas pressure less than or equal to 2000 psig. 11. A method in accordance with claim 10, wherein said liquid pressure is greater than said gas pressure. 12. A method for removal of hydrogen sulfide from a gas comprising said hydrogen sulfide, the method comprising the steps of: introducing a liquid comprising an hydrogen sulfide scavenging agent into a lumen of at least a portion of a plurality of porous hollow fibers of a hollow fiber membrane at a liquid pressure sufficient to overcome a resistance to wetting of said porous hollow fibers, thereby forming a liquid film on an outer surface of said portion of said plurality of porous hollow fibers; contacting said liquid film with said gas, thereby reacting in said gas at least a portion of said hydrogen sulfide with said hydrogen sulfide scavenging agent, forming at least one reaction product; and conducting said at least one reaction product away from said hollow fiber membrane. 13. A method in accordance with claim 12, wherein said gas is natural gas. 14. A method in accordance with claim 12, wherein a concentration of said hydrogen sulfide in said gas is in a range of about 4 ppmv to about 2000 ppmv. 15. A method in accordance with claim 12, wherein said hollow fiber membrane is an expanded polytetrafluoroethylene ribbon membrane. 16. A method in accordance with claim 12, wherein said hollow fiber membrane is one of an inorganic membrane and a ceramic membrane. 17.
