Abstract: Some examples include systems and methods for monitoring emission indications. A system has an image sensor to capture an image of a flare stack. A computer vision engine is configured to determine whether an emission indicator captured by the image indicates an emission event. A server engine is configured to transmit a notification indicating whether the emission indicator indicates the emission event to a control system of the flare stack. The computer vision engine is configured to update one or more model settings, one or more thresholds, or a combination thereof based on one or more settings. In one embodiment, the computer vision engine is configured to identify, using a deep convolutional neural network (DCNN) model, the emission indicator captured by the image.

Abstract: 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.

Abstract: 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.

Abstract: Systems and methods are provided for improving product yields and/or product quality during co-processing of fast pyrolysis oil in a fluid catalytic cracking (FCC) reaction environment. The systems and methods can allow for co-processing of an increased amount of fast pyrolysis oil while reducing or minimizing coke production for a feedstock including fast pyrolysis oil and a conventional FCC feed. The reducing or minimizing of coke production can be achieved in part by adding a low molecular weight, non-ionic surfactant to the mixture of fast pyrolysis oil and conventional FCC feed.

Abstract: The present techniques are directed to a multiphase separation system. The system includes a liquid-liquid separator configured to receive a separated liquid that is further separated into a separated oil and a separated water within the liquid-liquid separator. An oil pump and a water pump, both with adjustable speeds, are configured to pump the separated oil and the separated water, respectively, from the liquid-liquid separator. An interface level in the liquid-liquid separator is regulated by adjusting the speed of the oil pump and the speed of the water pump.
