Patent number: 11162389Abstract: A system for providing supercritical steam including a first boiler that generates steam via combusting a first fuel, and a second boiler fluidly connected to the first boiler via a conduit which heats the generated steam to supercritical steam temperatures via combusting a second fuel. A first temperature of the conduit may be below a critical corrosion temperature and a second temperature of the conduit is greater than or equal to the critical corrosion temperature. A combined carbon emission rate of the first boiler and the second boiler may be less than a combined carbon emission rate of generating and heating the steam to supercritical steam temperatures using boilers that only combust the first fuel. The first boiler may be fluidly connected to a heat exchanger that heats the generated steam to a supercritical steam temperature via a flue gas produced by a gas turbine.Type: GrantFiled: September 25, 2019Date of Patent: November 2, 2021Assignee: SAUDI ARABIAN OIL COMPANYInventors: Wei Zhang, Armand Levasseur, Tidjani Niass, Mourad Younes, Glen Jukkola, Bruce Wilhelm, Daryl Philo, Timothy Maidenford

Patent number: 10596583Abstract: A system for regulating the viscosity of a fluid prior to atomization includes a temperature controller configured to adjust a temperature of a fluid flowing in a conduit prior to atomization of the fluid by an atomizer fluidly connected to the conduit and a sensor in communication with the temperature controller such that the sensor can provide an indicator to the temperature controller of a viscosity of the fluid flowing in the conduit prior to atomization. An adjustment to the temperature of the fluid by the temperature controller is based at least in part on the measured viscosity indicator of the fluid, a target atomization-viscosity of the fluid, and a coking temperature of the fluid.Type: GrantFiled: May 11, 2016Date of Patent: March 24, 2020Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Armand Levasseur, Carl Edberg, Olaf Stallmann, Mourad Younes, Aqil Jamal

Patent number: 9791852Abstract: A method for controlling at least one operational parameter of a plant (1) having a combustion unit (3) can include estimating a status of at least one operational variable of the plant to identify an estimated value for the operational variable. For each operational variable, the estimated value for the operational variable can be compared with a measured value of the operational variable to determine an uncertainty value based on a difference in value between the measured value and the estimated value for the operational variable. A control signal can be generated based on a reference signal, the measured value, and the deviation value for sending to at least one element of the plant (1) for controlling a process of the plant (1).Type: GrantFiled: August 21, 2014Date of Patent: October 17, 2017Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Xinsheng Lou, Chuan Wang, Carl H.
