Patent ID: 8728325

Claim:
A process for treating kinetic hydrate inhibitor (KHI) containing aqueous solutions comprising: a) mixing one or more said kinetic hydrate inhibitor (KHI) containing aqueous solutions with a KHI degrading oxygen containing molecule to obtain a KHI degraded solution containing precipitates, wherein the KHI degrading oxygen containing molecule is provided by the step of (i) adding hydrogen peroxide then adding iron in a 2+ oxidation state (Fenton's Process); (ii) bubbling with ozone (ozonation); or (iii) both (i) and (ii); b) separating the precipitates from the KHI degraded solution; and c) obtaining clean water; wherein the KHI is a branched methoxylate, ethoxylate, propoxylate, butoxylate, pentoxylate, hexoxylate, carboxylate, ester, or other oxygenated KHI.
