Reaction gases are quenched with H₂O, then passed through a turbine where the pressure is allowed to drop.  The temperature drops and power is developed.  H₂O is condensed and collected in an accumulator or scrubber connected to the turbine.  The gases go from the scrubber to a H₂O absorber, where the oxygenated compounds are removed.  Heat of compression causes the temperature to rise, and this heat is removed by a cooler between the compressor and the absorber.  Unreacted gases are recycled in the reaction zone.  The centrifugal compressor may be placed on the discharge side of the H₂O absorber, which eliminates the necessity of having the compressor made of stainless steel.  The process is applied to the partial oxidation of hydrocarbons to obtain organic oxygenated compounds.  8 United States patents cited.
