Claims
- 1. A method for preventing fouling of equipment used in hydrocarbon processing which comprises adding to said hydrocarbon an antifouling agent represented by the formula; ##STR8## wherein R is a linear alkyl radical having from about 6 to 15 carbon atoms or an alkyl phenyl radical wherein the alkyl group contains from about 8 to 10 carbon atoms, R.sub.1 is H or CH, n is a number from 3 to 8, x is 3 or 4 and M.sup.+ is an ammonium or an alkali metal cation.
- 2. The method of claim 1 wherein R is a linear alkyl radical having from 8 to 10 carbon atoms, R.sub.1 is H, n is 3, x is 4 and M.sup.+ is an ammonium cation.
- 3. The method of claim 1 wherein R is an alkyl phenyl radical wherein the alkyl group contains from 8 to 10 carbon atoms, R.sub.1 is H, n is a number from 2 to 4, x is 3 or 4 and M.sup.+ is selected from the group consisting of NH.sub.4.sup.+, Na.sup.+ and K.sup.+.
- 4. The method of claim 1 wherein the amount of anti-fouling agent added is from about 1.5 to about 150 parts per million based on the hydrocarbon.
- 5. The method of claim 1 wherein the amount of anti-fouling agent added is from about 5 to about 50 parts per million based on the hydrocarbon.
- 6. The method of claim 1 which further comprises adding to said hydrocarbon a surfactant represented by the formula; ##STR9## wherein R.sub.4 is a fatty acid radical containing from about 8 to 22 carbon atoms.
- 7. The method of claim 6 wherein R.sub.4 is a coconut oil fatty acid radical.
- 8. The method of claim 6 wherein said surfactant is added to said hydrocarbon in an amount from 5% to 30% by weight of said antifouling agent.
- 9. The method of claim 6 wherein said surfactant further comprises an anionic surfactant.
- 10. The method of claim 9 wherein said anionic surfactant is an amine sulfonate.
- 11. A method for preventing fouling of equipment used in hydrocarbon processing which comprises adding to said hydrocarbon an antifouling agent represented by the formula; ##STR10## wherein y is a number from 4 to 8.
- 12. The method of claim 11 wherein the amount of antifouling agent added to said hydrocarbon is from about 1.5 to about 150 parts per million based on said hydrocarbon.
- 13. The method of claim 11 which further comprises adding to said hydrocarbon a surfactant represented by the formula; ##STR11## wherein R.sub.4 is a coconut oil fatty acid radical.
- 14. The method of claim 13 wherein said surfactant is added to said hydrocarbon in an amount of from 5% to 30% by weight of said antifouling agent.
- 15. The method of claim 13 wherein said surfactant further comprises an amine sulfonate.
- 16. A method for preventing fouling of equipment used in hydrocarbon processing which comprises adding to said hydrocarbon from 5 to 50 parts per million of antifouling agent represented by the formula; ##STR12## wherein y is a number from 4 to 8 and from 5% to 30.0% by weight of said antifouling agent of a surfactant represented by the formula; ##STR13## wherein R.sub.4 is coconut oil fatty acid radical.
- 17. The method of claim 16 wherein said surfactant further comprises an anionic surfactant.
