ABSTRACT:
A method for treating a fluid having hydrate-forming constituents is provided. In one or more embodiments, the method includes including a mixture (110) comprising glycol and one or more kinetic inhibitors to a fluid (105) that includes one or more hydrate-forming constituents and water to provide a treated fluid comprising the glycol, one or more kinetic inhibitors, one or more hydrate-forming constituents and water. The treated fluid (125) is then separated at conditions sufficient to provide an oil phase stream and an aqueous phase stream, wherein the aqueous phase stream includes one or more kinetic inhibitors, glycol and water.
