ABSTRACT:
This invention relates to a process and apparatus for dissipating the energy of a wet oxidation mixture after that stream traverses a pressure control valve. The depressurized stream is discharged into a phase separator vessel containing a gas phase and a liquid phase. The pressure control valve is positioned to discharge the oxidation mixture at a selected orientation below the surface level of the liquid phase in the vessel. This dissipates the energy of the mixture and prevents erosion of the phase separator vessel. The apparatus of the invention includes the separator vessel with gas and liquid phase exits, a control device for maintaining the liquid phase at the selected level in the vessel, a pressure control valve positioned at an aperture in the vessel for discharging the mixture below the surface level of the liquid phase in the vessel, and sealing device between the control valve and the separator vessel.
