Abstract : Investigative work carried out under Contract DAAK 02-69-C-0643, demonstrated that high voltage alternating electric fields could de-stabilize water-in-fuel emulsions using No. 2 Diesel as the test fuel. Other fuels such as JP-5 and gasoline were also successfully treated in this manner. A design scale-up was made from the 10-gpm breadboard model built and operated previously to a 100-gpm pilot model, improved de-entrainment means, and automatic water drain control. Implicit in the scale-up design was modification of electrode structure to permit more practical means of fabricating the larger electrodes. This matter together with de-entrainment studies and automatic drain provisions are described. Initial design studies indicated that two concepts offered individual advantages. The use of separate vessels for the electrocoalescer and filter units offered simplicity of design. The unit constructed in this manner is described. The second design in which both the electrocoalescer and filters were housed in a single vessel provided a more compact arrangement. The unit built in accordance with this design (integral unit) is described. Test results with the two vessel designs are summarized.
