Oxygen/hydrocarbon rapid (high shear) gas mixer, particularly for the production of ethylene oxide
A gas mixer is disclosed which includes a vessel (10) (e.g., pipe) containing a stream (12) of a first hydrocarbon-containing gas. The mixer includes a hollow pipe (14) located internal to the vessel containing a stream of a second gas, e.g., an oxygen-containing gas stream such as a stream of pure...

| description | A gas mixer is disclosed which includes a vessel (10) (e.g., pipe) containing a stream (12) of a first hydrocarbon-containing gas. The mixer includes a hollow pipe (14) located internal to the vessel containing a stream of a second gas, e.g., an oxygen-containing gas stream such as a stream of pure oxygen gas or air enriched with oxygen. The internal pipe further includes a mixer tip (30) at the peripheral end thereof. The mixer tip includes a body having an internal passage for conducting the second gas out of the pipe and an opening introducing the second gas stream into the first gas stream in a radial plane at an acute angle relative to the longitudinal axis of the pipe. The pipe further includes a deflector (20) on its external surface in longitudinal alignment with the opening of the mixer tip. The deflector serves to deflect any entrained particles within the first gas stream away from the mixing zone where the two streams mix, minimizing the risk of ignition of the hydrocarbon-containing gas. |
