Abstract: Embodiments of the present invention relate to a mixing apparatus. Particularly, embodiments of the present invention provide a mixing apparatus for mixing fluid components such as phosgene and amine during a highly reactive chemical reaction. One embodiment provides a mixing conduit comprising a cylindrical sidewall defining an inner volume, wherein one or more jets are formed through the cylindrical sidewalls and connect to the inner volume and one or more flow obstructions disposed in the inner volume, wherein each flow obstruction is positioned upstream from an associated aperture.

Abstract: The present invention includes a foam-forming composition for use in enhanced oil recovery, and a method of using said foam-forming composition for recovering oil. The foam-forming composition of the present invention comprises a nonionic surfactant, in particular an alcohol-alkoxylate, and an anionic surfactant, in particular an alkyl diphenyloxide (di)sulfonate, where the foam-forming composition promotes a formation of a stable foam formed of a CO2 and water.

Abstract: A method for recovering oil from an oil bearing formation including the steps of: i) recovering an oil-water mixture from the oil-bearing formation; ii) separating at least a portion of the oil from the oil-water mixture to form a produced water; iii) adding a polymeric alkylene oxide surfactant having a Mw of less than 10000 Da to the produced water; iv) passing the produced water through a polymeric membrane to form a permeate stream and a retentate stream; and v) injecting the permeate stream into the oil bearing formation.
