Abstract:
1. Method for extraction of fat or oil soluble components from produced water which is separated from an oil and/or gas plant, comprising: separating hydrocarbons from the oil and/or gas plant and using the separated hydrocarbons as an injection liquid which has a lower content of the fat or oil soluble components than is in contained in the produced water, adjusting a temperature of the injection liquid with respect to a temperature of the produced water and adjusting the bubble point pressure with respect to a pressure of the produced water separated from the oil and/or gas plant, into which the injection liquid is to be injected, injecting the injection liquid into the produced water and atomizing the injection liquid in the produced water so that the produced water is exposed to the atomized injected injection liquid for a time sufficient to allow mass transfer of the fat or oil soluble components from the produced water to the injection liquid, and separating the injection liquid from the produced water in a separator.
