SYSTEMS AND METHODS FOR PROCESSING GASES

The invention includes a gas processing system for transforming a hydrocarbon-containing inflow gas into outflow gas products, where the system includes a gas delivery subsystem, a plasma reaction chamber, and a microwave subsystem, with the gas delivery subsystem in fluid communication with the plasma reaction chamber, so that the gas delivery subsystem directs the hydrocarbon-containing inflow gas into the plasma reaction chamber, and the microwave subsystem directs microwave energy into the plasma reaction chamber to energize the hydrocarbon-containing inflow gas, thereby forming a plasma in the plasma reaction chamber, which plasma effects the transformation of a hydrocarbon in the hydrocarbon-containing inflow gas into the outflow gas products, which comprise acetylene and hydrogen. The invention also includes methods for the use of this gas processing system.

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.
