Abstract:
1. A method comprising: 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 a first electrocoagulation to yield a first effluent water and a coagulated organic material, wherein the first effluent water has a concentration of the organic material of greater than about 25 ppm; and retreating the first effluent water via a second electrocoagulation to yield a second effluent water, wherein a concentration of the organic material in the second effluent water has been reduced by about 95% or more as compared to the water before electrocoagulation.
