Abstract

Fuel scrubbing technology could be used for fuel tank inerting and fuel deoxygenation. Both N2 and CO2 are perfect inert gases, but the solubility of CO2 is nearly 20 times higher than that of N2 in jet fuels, so the scrubbing inerting process varies with the selection of N2 or CO2. A scrubbing test bench is constructed, and the variation of oxygen concentration on ullage or in the fuel is measured under various flow rates, fuel loads and initial oxygen concentrations on ullage. Experimental results reveal that the ullage and dissolved oxygen concentrations of CO2 scrubbing are always higher than that of N2 scrubbing. The inerting time of CO2 scrubbing of a 30%, 50% and 70% fuel load is approximately 1.42, 1.7 and 2.75 times that of N2 scrubbing, respectively. The scrubbing test under 5%, 9% and 14% initial ullage oxygen concentration revels a peak in ullage oxygen concentration of 7.23% and 9.97% for N2 scrubbing and that of 12.63%, 13.4% and 15.4% for CO2 scrubbing, respectively.
