摘要： A method includes receiving data characterizing a speed of an acoustic signal through a gas mixture in a pipe. The speed of the acoustic signal can be detected by an ultrasonic flow meter coupled to the pipe. The method also includes receiving data characterizing a concentration of one or more inert gases in the gas mixture detected by an inert gas analyzer. The method further includes determining, based on the received data characterizing the speed of the acoustic signal and the received data characterizing the concentration of the one or more inert gases in the gas mixture, a net heating value of the gas mixture. The method also includes adjusting a processing of the gas mixture based on the determined net heating value.

摘要： Systems and methods for monitoring emissions of a combusted gas are provided. The method includes determining a first net heating value of a flare gas. The method also includes determining a second net heating value of a combustion gas including the flare gas. The second net heating value can be determined based upon the first net heating value and a volumetric flow rate of the flare gas. Based upon the value of the second net heating value, an empirical model or a non-parametric machine learning model can be selected. A combustion efficiency of the combustion gas can be determined using the selected model, the second net heating value, and selected ones of the process conditions and the environmental conditions. Total emissions of the combustion mixture can be further determined from the combustion efficiency and a volumetric flow rate of the combustion gas.

摘要： A method for baseline calibration of methane sensor includes receiving data characterizing methane detection by a sensor and sensor measurement parameters. The received data characterizing methane detection includes a plurality of methane measurements and detection times associated with the plurality of methane measurements. The method also includes determining a first plurality of calibrated methane measurements by at least calibrating the plurality of methane measurement based on the sensor measurement parameters and one or more of a humidity and a temperature associated with the sensor. The method further includes calculating an offset parameter based on a difference between a global baseline reference and one of a previous baseline value and a measurement baseline value associated with the first plurality of calibrated methane measurements. The method also includes providing a second plurality of calibrated methane measurements by at least subtracting the offset parameter from the first plurality of calibrated methane measurements.
