Functionalized alpha-hydroxy alkyl ethers have been found to perform as non (or anti-) scaling hydrogen sulfide scavengers. A method of scavenging hydrogen sulfide includes contacting a fluid containing hydrogen sulfide with a treatment fluid including a functionalized alpha-hydroxy alkyl ether. Accordingly, the alpha-hydroxy alkyl ether reacts with the hydrogen sulfide to reduce the amount of hydrogen sulfide in the fluid. The functionalized alpha-hydroxy alkyl ether is functionalized with a phosphate group, phosphonate group, sulfate group, or sulfonate group. A broad range of alpha-hydroxy alkyl ethers are disclosed.

1. A method of reducing the amount of hydrogen sulfide in a hydrocarbon-containing fluid, the method comprising: contacting the hydrocarbon-containing fluid with a treatment fluid including a functionalized alpha-hydroxy alkyl ether, wherein the hydrogen sulfide reacts with the functionalized alpha-hydroxy alkyl ether to reduce an amount of the hydrogen sulfide in the hydrocarbon-containing fluid, and wherein the functionalized alpha-hydroxy alkyl ether is selected from glycerol bis hemiformal mono phosphate ether, oligomeric glycerol bis hemiformal di-phosphate ether, glycerol bis hemiformal mono sulfate ether, oligomeric glycerol bis hemiformal di-sulfate ether, or a combination thereof; wherein the hydrocarbon-containing fluid is a production fluid that has been produced from a subterranean formation. 2. The method of claim 1, wherein the alpha-hydroxy alkyl ether has no nitrogen or basic nitrogen. 3. The method of claim 1, wherein the alpha-hydroxy alkyl ether includes two phosphate groups, or two sulfate groups. 4. The method of claim 1, wherein the alpha-hydroxy alkyl ether is glycerol bis hemiformal phosphate. 5. The method of claim 1, wherein the alpha-hydroxy alkyl ether is selected from glycerol bis hemiformal mono phosphate ether, oligomeric glycerol bis hemiformal di-phosphate ether, or a combination thereof. 6. The method of claim 1, wherein the alpha-hydroxy alkyl ether is selected from glycerol bis hemiformal mono sulfate ether, oligomeric glycerol bis hemiformal di-sulfate ether, or a combination thereof. 7. The method of claim 1, wherein the treatment fluid includes between 5 and 20 volume percent of the alpha-hydroxy alkyl ether. 8. The method of claim 1, wherein the treatment fluid includes between 10 and 15 volume percent of the alpha-hydroxy alkyl ether. 9. The method of claim 1, wherein the treatment fluid includes a mixture of water and ethanol. 10. The method of claim 1, wherein the hydrocarbon-containing fluid containing hydrogen sulfide comprises a gas. 11. The method of claim 10, wherein the contact between the hydrocarbon-containing production fluid and the treatment fluid occurs in an absorption tower. 12. The method of claim 1, wherein contacting a fluid containing hydrogen sulfide with a treatment fluid including the functionalized alpha-hydroxy alkyl ether, comprises: pumping the treatment fluid under pressure through a wellbore into a subterranean formation and maintaining the treatment fluid in the region around the wellbore for a predetermined period of time, wherein the alpha-hydroxy alkyl ether adsorbs onto the subterranean formation in a region around the wellbore; andflowing production fluids from the subterranean formation into the wellbore, wherein the hydrogen sulfide reacts with the functionalized alpha-hydroxy alkyl ether as the production fluids flow through the region around the wellbore, and wherein the production fluids contain hydrogen sulfide that reacts with the alpha-hydroxy alkyl ether to reduce an amount of hydrogen sulfide in the production fluids before the production fluids flow into the wellbore. 13. The method of claim 12, wherein the treatment fluid is maintained in the region around the wellbore for a predetermined period of time to allow the compound for scavenging hydrogen sulfide to absorb onto the subterranean formation. 14. The method of claim 13, wherein the predetermined period of time is between 12 and 16 hours. 15. The method of claim 13, wherein the predetermined period of time is greater than 16 hours.
