Norway: Deoxygenation process treats seawater for injection ///

The Minox process, developed during 1985 – 90 by Minox and Norsk Hydro’s Porsgrunn Research Center, is based on stripping oxygen from seawater in a two-stage operation that circulates nitrogen gas. A key process feature is the method of contacting the nitrogen stream with the incoming seawater. By doing this in static mixers, co-current turbulent flow is achieved, producing highly efficient mixing of liquid and gas and simultaneous stripping of the dissolved oxygen from the seawater to very low concentrations.
