Abstract:
1. Process for treating effluents from oil production units to remove oil and other soluble toxic contaminants, before discharging or reusing this effluent, in an offshore environment, comprising the following steps: a) pumping an effluent, containing an oil-in water emulsion and soluble toxic contaminants, from a first storage tank via a first supply line; b) pumping an oxidizing agent from a second storage tank via a second supply line, wherein the oxidizing agent consists of hydrogen peroxide (H c) directing both the first supply line and the second supply line into a third supply line in order to promote first mixing between the effluent and the oxidizing agent; d) transferring the mixture of the effluent and the oxidizing agent from the third supply line to a mixing device; e) promoting agitation of the mixture of the effluent and the oxidizing agent in order to bring about at least a redox reaction and the resulting destabilization of the oil-in-water emulsion; f) directing the contents of the mixing device via a transfer line to a separating device; g) separating the treated effluent, by means of the separating device, into two distinct phases: a first phase containing predominantly water and a second phase containing oil and the soluble toxic contaminants.
