Abstract: The present disclosure is directed to systems and methods for low-CO2 emission combustion of liquid fuel with a gas-assisted liquid fuel oxygen reactor. The system comprises an atomizer that sprays fuel and CO2 into an evaporation zone, where the fuel and CO2 is heated into a vaporized form. The system comprises a reaction zone that receives the vaporized fuel and CO2. The system includes an air vessel having an air stream, and a heating vessel adjacent to the air vessel that transfers heat to the air vessel. The system comprises an ion transport membrane in flow communication with the air vessel and reaction zone. The ion transport membrane receives O2 permeating from the air stream and transfers the O2 into the reaction zone resulting in combustion of fuel. The combustion produces heat and creates CO2 exhaust gases that are recirculated in the system limiting emission of CO2.

Abstract: An integrated ITM micromixer burner shell and tube design for clean combustion in gas turbines includes an oxy-fuel micromixer burner for separating oxygen from air within the burner to perform oxy-combustion, resulting in an exhaust stream that consists of CO2 and H2O. The shell and tube combustion chamber is designed so that preheated air enters a headend having an array of ion transfer membrane (ITM) tubes that separate oxygen from the preheated air and anchor flamelets on the shell side. The combustion products of the oxy-fuel flamelets expand through a turbine for power generation, before H2O is separated from CO2 by condensation. A portion of the effluent CO2 is compressed back into the burner system, while the remainder is captured for sequestration/utilization.

Abstract: A power generation system that includes a membrane reformer assembly, wherein syngas is formed from a steam reforming reaction of natural gas and steam, and wherein hydrogen is separated from the syngas via a hydrogen-permeable membrane, a combustor for an oxy-combustion of a fuel, an expander to generate power, and an ion transport membrane assembly, wherein oxygen is separated from an oxygen-containing stream to be combusted in the combustor. Various embodiments of the power generation system and a process for generating power using the same are provided.

Abstract: The power turbine system includes two power turbines communicating with an ion transport membrane (ITM) reactor. Heavy liquid fuel is atomized and burned within the reactor to drive the first turbine, with the first turbine producing useful power. Exhaust from the first turbine is recycled back into the reactor. The reactor includes a series of concentric cylindrical ion transport membranes that separate atmospheric and exhaust gases into suitable components for combustion therein, with at least some of the gases being “cracked” to alter their molecular structure for further combustion to power the second turbine. The second turbine drives a compressor to supply air to the reactor. At least one of the ITMs precludes atmospheric nitrogen from the combustion processes, with the resulting exhaust including pure water and carbon dioxide. The carbon dioxide is either recycled into the reactor to facilitate fuel atomization, or compressed for sequestration.

Abstract: A power generation system using a combined solar-assisted fuel reformer and oxy-combustion membrane reactor is proposed. The system uses solar heating to activate the endothermic fuel steam reforming reaction. The produced gas is separated into streams of H2 and CO for separate oxy-combustion reactions. The O2 used in the oxy-combustion reactions is produced by permeating O2 through ion transport membranes in contact with solar-heated air.
