Method for producing acetylene and syngas

A process for producing acetylene and syngas by partial oxidation of hydrocarbons with oxygen, involving: separately preheating a hydrocarbon and a oxygen-comprising input stream; mixing in a mass flow ratio of the oxygen-comprising to hydrocarbon stream at an oxygen number no more than 0.31; feeding the streams via a burner block to a combustion chamber and therein partially oxidizing the hydrocarbon(s) to a cracking gas; quenching the cracking gas to 80 to 90° C. downstream by injecting an aqueous quench medium to obtain a process water stream-1 and a product gas stream-2; cooling the product gas stream-2 in a cooling column by direct heat exchange with cooling water to obtain a process water stream-2 as bottoms, a product gas stream-2 as uppers, and a sidestream; and depleting the sidestream of soot in an electrofilter to generate therein a process water stream-3 combined with water streams-1/2 to afford the process water stream-4.

Process for producing acetylene and ethylene

A process for producing acetylene, ethylene, or both is disclosed. The process includes combusting a fuel stream to produce a combustion gas effluent stream and pyrolyzing a feed stream in a pyrolysis zone in the presence of the combustion gas effluent stream to produce a pyrolysis zone effluent stream which is further quenched and compressed. The compressed quenched stream is separated in a solvent separation column to produce a net gas stream comprising hydrogen, methane, and at least one carbon oxide and a product stream. A portion of the carbon oxide of the net gas stream is converted into methane in a methanation reactor and a reactor effluent stream is sent to an amine scrubber where carbon dioxide is removed and a methane containing stream is generated as an effluent. The methane containing stream is then recycled to the pyrolysis zone of the supersonic reactor.

An integrated process for producing acetylene is provided. The process comprises separating a gas stream comprising methane from a fuel gas stream in a fuel gas recovery unit of a process. A fuel and an oxidizer are combusted in a combustion zone of a pyrolytic reactor to create a combustion gas stream, wherein the pyrolytic reactor is integrated with the fuel gas recovery unit via the gas stream comprising methane. A light hydrocarbon stream comprising all or a first portion of the gas stream comprising methane is injected into a supersonic combustion gas stream to create a mixed stream. The velocity of the mixed stream is transitioned from supersonic to subsonic in a reaction zone of the pyrolytic reactor to produce a reaction mixture comprising acetylene, methane, carbon oxides, and hydrogen. The reaction mixture is separated to provide an acetylene stream.
