The theory governing the removal of free and dissolved water by gas blowing is discussed and equations for pre-dieting the performance of continuous counter current flow drying units are developed using a concept of effective theoretical plates. From the general equation derived, it is shown that the performance of any particular fuel drying unit is dependent on the efficiency of the drying tower employed effective number of theoretical plates, the ratio of the rates of gas to fuel flow used, the dryness of the inlet gas, the moisture content of the entering fuel and the temperature of operation. A number of solutions applicable to the dehydration of JP-5 fuel under a variety of operating conditions are included to demonstrate the relative importance of the above parameters and to illustrate the type of performance possible.
