    摘要: Systems and methods are provided for integrating a chemical looping combustion system with molten carbonate fuel cells to provide improved operation of the molten carbonate fuel cells when using the exhaust from a gas turbine or other electrical power generation device as the CO2 source for the MCFC cathodes. This integration can be accomplished by using metal oxide in the chemical looping combustion system to oxidize the anode output flow from the MCFCs. This can reduce or minimize the number of separations that need to be performed in order to process the concentrated CO2 present within the anode exhaust. By reducing, minimizing, or eliminating the CO and H2 in the anode exhaust, the need to perform more costly separations (such as cryogenic separation or amine washing) to obtain a high purity CO2 product stream can be reduced or minimized. Optionally, the cathode exhaust from the molten carbonate fuel cells can be used as an oxygen-containing stream for regeneration of the metal oxide.

    摘要: Disclosed is a staged-air burner device capable of high energy efficiency, high flame stability, combusting multiple readily switchable fuels ranging from pure hydrogen, to any hydrogen/methane mixture, to pure methane, and generating a low level of NOx. The burner device can include: a primary air chamber receiving a primary air and a flue gas; a burner tube capable of receiving a fuel jet and drawing in the air-flue gas mixture from the primary air chamber; a burner tip discharging the fuel-air-flue gas mixture formed in the burner tube to a first combustion zone and a second combustion zone via center orifices and side orifices on the burner tip, respectively; and a staged air chamber receiving staged air and discharging it via staged air ports into a third combustion zone. Combustion of the fuel occurs in at least one of the first, second, and third combustion zones.

    摘要: Age differentiation of hydrocarbon samples may be achieved using a chemical fossil assemblage approach. For example, a method may comprise: determining a source facies for a hydrocarbon sample; inputting the source facies into a chemical fossil assemblage model; determining, using the chemical fossil assemblage model, one or more candidate chemical fossil assemblages and corresponding age biomarkers for the hydrocarbon sample based on the source facies; measuring a concentration or a related value of corresponding age biomarkers in the hydrocarbon sample to yield an age biomarker fingerprint; inputting the age biomarker fingerprint into a chemical fossil assemblage model; comparing the age biomarker fingerprint to the one or more candidate chemical fossil assemblages using the chemical fossil assemblage model; and estimating an age of the hydrocarbon sample based on the comparison.
