Abstract: 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.

Abstract: A process and system for monitoring and controlling the operation of a dehydrogenation reactor is provided. Samples of hydrocarbon streams are taken at sampling locations to be analyzed at a single gas chromatograph or other analytical equipment. Actions can be taken to modify the operation of the dehydrogenation reactor as necessary to maintain its operation within predetermined parameters. In particular, actions may be taken when a hydrocarbon stream exhibits an amount of cracking that is outside parameters. It is usually intended that actions will be taken on a gradual basis once or twice per day to reduce the cost of the process while still providing the necessary changes to operations.

Abstract: 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.

Abstract: A method for conditioning natural gas into fuel gas, where the method includes the step of: delivering a natural gas stream including both CO2 and C2+ hydrocarbons to a membrane separation assembly; and separating the natural gas stream into the following streams: (i) a first permeate stream, (ii) a second permeate stream, and (iii) a residual stream. The first permeate stream includes CO2 removed from the natural gas stream. The second permeate stream includes methane at a greater concentration than a concentration of methane in the natural gas stream. The residual stream contains C2+ hydrocarbons at a greater concentration than a concentration of C2+ hydrocarbons in the natural gas stream.
