QUESTIONS OF SELF-CALIBRATION OF SATELLITE TOOLS FOR DETERMINING THE VOLUME OF BURNED ASSOCIATED GAS IN FLARE

The possibility of carrying out mutual calibration of satellite means for determining the volume of associated gas burned in flares was analyzed. Existing satellite methods for estimating the total amount of associated hydrocarbon gas flared, implemented on the basis of MODIS and VIIRS data, are considered. Methods have been developed for inter sensor calibration of satellite meters, implemented by introducing an additive calibration correction for the measured temperature of objects outside the plume in the first case, when the MODIS data are calibrated according to the VIIRS readings and for the plume emissivity, in the case when the VİİRS readings are calibrated according to the MODIS readings. The problem of the optimal choice of the temperature of the gas torches, at which the emission of an aerosol such as elemental carbon (BC) can be reduced in comparison with the maximum generation level, is considered and solved. With the full knowledge of the frequency statistics of the appearance of low-temperature flares and the appearance of high-temperature flares, the proposed mathematical model allows us to estimate the maximum formation of a dangerous aerosol to prevent the formation of a hazard and allows us to calculate the remaining quantities if the values of five quantities are known from the set of variables participating in the model. The proposed model makes it possible to determine the maximum emission and its average temperature expectation. Keywords: Associated gas, calibration, satellite measurements, flame, temperature.
