Elaboration of the continuous method for degassing hydrocarbon fuels and the installation for its implementation

Oxidation of hydrocarbon fuels with oxygen of dissolved air leads to the loss of its quality and, ultimately, to the abnormal operation of facilities using it, determining the need to elaborate a method for fuel degassing. On the basis of hydrocarbon fuel degassing process regularities, a theoretical analysis of gas desorption from liquids upon degassing was carried out, a mathematical model for calculating the degassing process under static vacuum conditions, as well as a mathematical model of liquid degassing with the method of forced gas boiling under dynamic conditions were proposed. Based on the carried out experimental and theoretical studies and calculations, an efficient method of continuous degassing of hydrocarbon fuels and a scheme of the installation for its implementation were proposed. Results of the experimental studies which confirm the high efficiency of the proposed degassing method are reported.
