Abstract
Electrocoagulation may be used to reduce the concentration of hydrate inhibitors in produced water. For example, a method may include producing a fluid from a subterranean formation, the fluid comprising petroleum hydrocarbons and water, the water having an organic material that includes hydrate inhibitors dispersed therein, wherein the hydrate inhibitors are at a concentration of about 30 ppm or greater in the water; separating the petroleum hydrocarbons from the water and the organic material; and separating at least some of the organic material from the water via electrocoagulation to yield an effluent water and a coagulated organic material.
