FIELD: oil hydrocarbons mass measuring.
SUBSTANCE: claimed invention relates to methods for measuring the mass of oil hydrocarbons. In the method, after draining the transport tank, the height of the level of the technologically non-selectable liquid hydrocarbon residue at the bottom of the tank is measured, the density of the drained product is determined, the volume of the liquid hydrocarbon residue is determined according to the calibration table for the transport tank, the geometric dimensions of the transport tank are additionally measured, he volume concentration of hydrocarbon vapors inside the tank is measured, the temperature of the vapor-air mixture inside the tank is measured, the molar mass of hydrocarbon vapors is determined, the sticking coefficient of the drained product is determined, and the mass of hydrocarbons of oil and oil products Mo that form technological losses when draining transport tanks is calculated according to the appropriate formula.
EFFECT: increasing the accuracy of measuring the mass of hydrocarbons in oil and oil products, which form technological losses during the discharge of transport tanks.
