Abstract: The precipitation of polymeric kinetic hydrate inhibitors (KHIs) in stored produced water is prevented or inhibited by incorporating a water immiscible solvent therein having a polarity index greater than about 3. The polymeric KHIs whose precipitation is inhibited or prevented include, but are not limited to, hyperbranched molecules, polyvinylcaprolactam, polyvinylpyrrolidone, and the like. Suitable water immiscible solvents include, but are not necessarily limited to, xylene, toluene, kerosene, mineral spirits, trimethylbenzene, cumene, heavy aromatic naphtha, ethylbenzene, polyethylbenzene, naphthalene, and mixtures thereof.

Abstract: New tertiary amine salts are useful as gas hydrate inhibitors in oil and gas production and transportation. These tertiary amine salts give very good separation from an emulsion, are economic and have reduced toxicity concerns.
