Integrated process for producing acetylene

An integrated process for producing acetylene, comprising

• combusting a fuel and an oxidizer in a combustion zone of a pyrolytic reactor to create a combustion gas stream;
• accelerating a velocity of the combustion gas stream from subsonic to supersonic in an expansion zone of the pyrolytic reactor;
• injecting a light hydrocarbon stream into the supersonic combustion gas stream to create a mixed stream comprising the light hydrocarbon;
• transitioning the velocity of the mixed stream from supersonic to subsonic in a reaction zone of the pyrolytic reactor to produce a reaction mixture comprising acetylene, methane, carbon oxides, and hydrogen;
• passing the reaction mixture to a product recovery unit integrated with the pyrolytic reactor;
• and
• separating the reaction mixture in the integrated product recovery unit to provide an acetylene stream and a fuel gas stream comprising methane, carbon oxides and the hydrogen.

• accelerating a velocity of the combustion gas stream from subsonic to supersonic in an expansion zone of the pyrolytic reactor;
• injecting a light hydrocarbon stream into the supersonic combustion gas stream to create a mixed stream including the light hydrocarbon;
• transitioning the velocity of the mixed stream from supersonic to subsonic in a reaction zone of the pyrolytic reactor to produce a reaction mixture comprising acetylene, methane, carbon oxides, and hydrogen;
• separating the reaction mixture in a separation zone of the pyrolytic reactor into an acetylene stream and a byproduct stream comprising the methane, carbon oxides and the hydrogen;
• passing the byproduct stream to a product recovery unit integrated with the pyrolytic reactor, wherein the pyrolytic reactor is integrated with the product recovery unit via the byproduct stream;
• separating the byproduct stream in the product recovery unit to provide a gas stream comprising methane;
• and
• injecting all or a first portion of the gas stream comprising methane into the supersonic combustion gas stream.
