  • Steam to carbon ratio control in steam reforming of hydrocarbons
    Patent number: 6758101
    Abstract: A mass flowmeter system for use in steam reformation of hydrocarbons includes a Coriolis flowmeter in a hydrocarbon feedstock line. The feedstock carbon content is estimated by close approximation, which facilitates selective control operations governing the relative amounts of steam and hydrocarbon materials as they feed a hydrogen processing unit. The relative amounts of steam and hydrocarbon feedstock are adjusted on the basis of real time measurements.
    Type: Grant

  • Mass fraction metering device
    Patent number: 6612186
    Abstract: An energy metering device includes a volumetric flow meter or mass flow meter in combination with a gas analyzer that provides telemetry regarding the constituents of a natural gas flow stream. An interpreter analyzes this information and provides a real time output corresponding to the enthalpy of combustion for the gas stream. This output is used to adjust or throttle the gas flow stream for purposes of delivering the flow stream according to a preselected parameter, which is related to desired operating conditions for a combustion device including a boiler or an engine.
