Chemical reactor () and method for cracking are disclosed. A process fluid is accelerated with axial impulse impellers (A,B) to a velocity greater than Mach 1 and, in turn, generating a shock wave () in the process fluid by decelerating it in a static diffuser () having diverging diffuser passages (). Temperature increase of the process fluid downstream of the shockwave cracks or splits molecules, such as hydrocarbons entrained in the process fluid, in a single pass, through a unidirectional flow path (F), within a single stage, without recirculating the process fluid for another pass through the same stage. In some embodiments, a system involving at least two turbomachine chemical reactors () may provide multiple successive stages of one or more axial impulse impellers (A,B), paired with a diverging passage, static diffuser ().

Turbomachine chemical reactor and method for cracking

A turbomachine type chemical reactor for processing a process fluid is presented. The turbomachine type chemical reactor includes at least one impeller section and a stationary diffuser section arranged downstream. The impeller section accelerates the process fluid to a supersonic flow. A shock wave is generated in the stationary diffuser section that instantaneously increases static temperature of the process fluid downstream the shock wave for processing the process fluid. which allows thermally cracking a chemical compound, such as hydrocarbon, in the process fluid. Static pressure of the process fluid is simultaneously increased across the shock wave. The turbomachine type chemical reactor significantly reduces residence time of the process fluid in the chemical reactor and improves efficiency of the chemical reactor.

In some embodiments, the turbomachine chemical reactor () has multiple successive stages of one or more axial impulse impellers (A,B), paired with a diverging passage, static diffuser (). Successive stages crack additional hydrocarbons by successively raising temperature of the flowing process fluid.

Turbomachine chemical reactor and method for cracking hydrocarbons in a process fluid

A gas turbine assembly and method for operating the gas turbine assembly are provided. The method for operating the gas turbine assembly may include compressing a process fluid containing inlet air through a compressor to produce compressed inlet air, combining fuel from a main fuel source with the process fluid, and preheating the process fluid containing the inlet air and the fuel in a warmer disposed downstream from the compressor. The method may also include heating an oxidizer by flowing the preheated process fluid from the warmer to the oxidizer, and oxidizing the process fluid containing the compressed inlet air and the fuel in the oxidizer to produce an oxidation product. The method may further include expanding the oxidation product in a turbine to generate rotational energy, and preventing the process fluid from flowing upstream to the compressor with a check valve.
