Abstract
A method for reducing fouling in an aqueous system of an olefin production plant is disclosed. The method includes adding an effective amount of a surfmer to the aqueous system, wherein the surfmer forms a water soluble adduct by covalently bonding to one or more fouling precursor compounds formed during olefin production.
Claims18
A method for reducing fouling in an aqueous system of an olefin production plant, the method comprising:
- adding an effective amount of a polyethylene glycol (PEG) functionalized maleamide to the aqueous system,
- wherein the PEG functionalized maleamide forms a water soluble adduct by covalently bonding to one or more fouling precursor compound(s) formed during olefin production, and wherein the PEG functionalized maleamide has a chemical structure of formula I or formula II,
- wherein n, k and l are independently 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10.
