Publication number: 20170284294Abstract: Experimental and numerical investigations on an atmospheric diffusion oxy-combustion flame in a gas turbine model combustor are conducted. The combustor is fuelled with CH4CH4 and a mixture of CO2 and O2 as oxidizer. The stability of the oxy-combustion flame is affected when the operating percentage of oxygen in the oxidizer mixture is reduced below 25%. A new 3D reactor design is introduced for the substitution of ITM reactors into a gas turbine combustor. A new oxygen permeation equation model has been developed by fitting the experimental data available in the literature for a LSCF ion transport membrane. The monolith structure design ITM reactor is capable of delivering power ranging from 5 to 8 MWe based on cycle first law efficiency.Type: ApplicationFiled: April 19, 2017Publication date: October 5, 2017Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Medhat Ahmed NEMITALLAH, Mohamed Abdel-Aziz HABIB

Publication number: 20170218840Abstract: A zero-emission, closed-loop and hybrid solar-produced syngas power cycle is introduced utilizing an oxygen transport reactor (OTR). The fuel is syngas produced within the cycle. The separated oxygen inside the OTR through the ion transport membrane (ITM) is used in the syngas-oxygen combustion process in the permeate side of the OTR. The combustion products in the permeate side of the OTR are CO2 and H2O. The combustion gases are used in a turbine for power production and energy utilization then a condenser is used to separate H2O from CO2. CO2 is compressed to the feed side of the OTR. H2O is evaporated after separation from CO2 and fed to the feed side of the OTR.Type: ApplicationFiled: April 14, 2017Publication date: August 3, 2017Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Medhat Ahmed NEMITALLAH, Mohamed Abdel-Aziz HABIB

Patent number: 9383096Abstract: An oxygen transport reactor for boiler furnaces and gas turbine combustors that utilizes a liquid fuel that is oxidized as a gaseous fuel in a membrane reactor. A liquid fuel is introduced by vaporizing the fuel inside a porous pipe surrounded by an annulus reaction zone which is surrounded by an annulus air zone. An oxygen transport membrane separates the annulus reaction zone containing the porous vaporized fuel and sweeping CO2 from the air feed side zone. Oxygen is transported from the outer annulus through the membrane to the annulus reaction zone containing the vaporized fuel and sweeping CO2. Fuel is first cracked to very small droplets in the intake fuel atomizer utilizing part of the intake CO2 then completely vaporized inside the porous pipe utilizing the heat coming from the surrounding reaction zone. The oxygen transport reactor is applicable for carbon free boiler furnaces and gas turbine combustors which utilize oxygen transport reactors for combined oxygen separation and combustion.Type: GrantFiled: December 23, 2013Date of Patent: July 5, 2016Assignee: King Fahd University of Petroleum and MineralsInventors: Mohamed Abdel-Aziz Habib, Medhat Ahmed Nemitallah

Patent number: 9074559Abstract: The engine emissions control system using an ion transport membrane incorporates an ion transport membrane unit into a closed, recirculating intake and exhaust system in the engine. The unit has a housing defining an air intake channel separated from an exhaust gas recirculation channel by an ion transport membrane. The membrane is permeable to oxygen, but is impermeable to nitrogen, water and carbon dioxide. Oxygen drawn from ambient air in the air intake channel is transported through the membrane to enrich the flow of exhaust gases in the exhaust gas recirculation channel, which is transported through a conduit to the engine intake for combustion of hydrocarbon fuel. The oxygenated exhaust gases may include uncombusted fuel or incomplete combustion products. Exhaust and intake accumulators may smooth the gas pulses. The accumulated or excess carbon dioxide and water in the exhaust is recovered from the system into onboard storage tanks or containers.Type: GrantFiled: November 5, 2013Date of Patent: July 7, 2015Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Medhat Ahmed Nemitallah, Mohamed Abdel-Aziz Habib

Patent number: 8893505Abstract: The integrated solar-gas turbine cogeneration plant includes a fuel reformer, a plurality of solar collectors, and a gas turbine. The fuel reformer produces syngas to be used as fuel for the gas turbine. One solar collector is operatively connected to both the fuel reformer and the turbine to provide heat for the reforming reaction and to preheat air for a combustion chamber. Exhaust gas from the turbine is directed to the fuel reformer and to a heat recovery steam generator, the former as an additional heat source and the latter to heat the generator. Another solar collector is connected to the generator and heats a portion of the water being fed into the generator in order to help produce steam. The syngas is stored in a fuel storage unit to provide fuel to the gas turbine continuously and to a supplemental heater on the steam generator during low insolation periods.Type: GrantFiled: February 8, 2012Date of Patent: November 25, 2014Assignee: King Fahd University of Petroleum and MineralsInventors: Esmail M.

Patent number: 8820312Abstract: The oxygen transport reactor-based oven is an oven for heating articles, such as bread, using oxygen transport reactor-based combustion in order to recycle carbon dioxide, rather than releasing the carbon dioxide into the environment. The oven includes an upper furnace chamber having a plurality of oxygen transport reactors disposed therein. A mixture of fuel and gaseous carbon dioxide is delivered to the interior of each oxygen transport reactor. Pressurized air is then delivered to the upper furnace chamber, so that oxygen from the pressurized air is driven through an ion transport membrane of each oxygen transport reactor to combust with the fuel. This combustion produces carbon dioxide, water vapor and heat. The generated heat is used to heat the articles to be heated, which are received within a heating chamber positioned beneath the upper furnace chamber.Type: GrantFiled: December 6, 2011Date of Patent: September 2, 2014Assignee: King Fahd University of Petroleum and MineralsInventors: Mohamed Abdel-Aziz Habib, Esmail M.
