The method and system utilizes a sidedraw tray within the fractionator distillation zone upon which liquid is collected. This liquid is withdrawn as a sidedraw stream. The withdrawal of the liquid from the sidedraw tray is controlled based on the level of liquid on the sidedraw tray rather than at a set or determined flow rate. The sidedraw stream is separated into a first stream and a product stream. Unlike other processes where the flow rate of the product stream is set and the internal reflux flow rate varies, the method involves fixing the flow rate of the first stream that is returned to the distillation zone of the fractionators with the flow rate of the product stream being set so as to control the liquid level on the sidedraw tray.

First and second heat exchangers direct heat from products to reactants in the reaction zones. A controller controls the first and second actuators in a coordinated manner based at least in part on a flow rate of the second product from the second reaction zone.

  • Patent number: 8926720
    Abstract: The mass flow rate of a first reactant stream supplied to a fuel processor is controlled based on a combined feed-forward and feedback control regime. The method is particularly applicable for actively controlling the fuel supply to a fuel processor in a system comprising a combustion engine, in which the fuel processor is fluidly connected to receive at least a portion of an engine exhaust stream from the engine. In embodiments of the system and method, the supply of fuel is controlled based on three mass flow factors.

  • Patent number: 8920732
    Abstract: The present disclosure is directed to systems and methods for actively controlling the steam-to-carbon ratio in hydrogen-producing fuel processing systems that include a feedstock delivery system. The feedstock delivery system supplies a combined feedstock stream including steam and carbon-containing feedstock to a hydrogen-producing region, which produces a mixed gas stream including hydrogen gas as a majority component therefrom. The systems and methods may include measuring a thermodynamic property of a steam stream, a carbon-containing feedstock stream, and/or the combined feedstock stream and controlling the flow rate and/or pressure of a water stream, the steam stream, and/or the carbon-containing feedstock stream based on a desired steam-to-carbon ratio in the combined feedstock stream and/or a desired flow rate of the mixed gas stream and may include feedforward and/or feedback control strategies.

  • Publication number: 20140308186
    Abstract: Some industrial or fabrication processes generate effluent gas streams that require scrubbing. Scrubbing may include the use of one or more gases to abate the effluents for safer release into the environment. Systems and methods described herein provide a liquid-enclosed reaction chamber where an extended reaction zone or more than one reaction zone is formed. By having an extended reaction zone or more than one reaction zone, the effluent gas stream and the products of upstream reaction zones can be more completely abated. The reaction zones are formed by adding one or more gas ports into the reaction chamber downstream of a main burner nozzle.

    Abstract: An ammonia generating and delivery apparatus generating ammonia by heating a precursor material with a heating device controlled by a temperature pulse controller which receives commands from a pressure controller, and delivering ammonia with a flow rate controlled by a three-stage PWM controller. The temperature pulse controller is used in a first feedback loop to create a temperature pulse sequence at a surface of the heating device. A pressure controller in a second feedback loop provides duty-cycle commands to the temperature pulse controller, while in delivering ammonia, effects of pressure variation to delivery accuracy are compensated in the three-stage PWM controller, which includes a flow-rate feedback loop. The ammonia generating and delivery apparatus can also include two containers, in which the precursor material in one container is charged and discharged according to the capability of the other container in generating ammonia.
