Claim 1
Independent Claim
143 words
IN APPARATUS FOR BREAKING EMULSIONS WHICH COMPRISES A HORIZONTALLY DISPOSED VESSEL, AN EMULSION FEED INLET AT ONE END OF SAID VESSEL, AND OUTLET FOR OIL AND AN OUTLET FOR WATER AT THE OPPOSITE END OF SAID VESSEL, A PLURALITY OF SPACED-APART ELECTRODES WITHIN SAID VESSEL ADJACENT SAID INLET, MEANS FOR IMPOSING ELECTRICAL POTENTIALS OF OPPOSITE POLARITY ON ADJACENT ELECTRODES, AND A PLURALITY OF COALESCENT SURFACES DISPOSED WITHIN SAID VESSEL INTERMEDIATE SAID ELECTRODES AND SAID OUTLETS, THE IMPROVEMENT WHICH COMPRISES AN ELECTRODE ARRANGEMENT INCLUDING AN ELONGATED HORIZONTALLY DISPOSED CENTRAL ELECTRODE AND AT LEAST ONE ADDITIONAL ELECTRODE COAXIALLY ARRANGED WITH RESPECT TO SAID CENTRAL ELECTRODE, SAID ELECTRODE ARRANGEMENT BEING SUCH THAT, IN THE DIRECTION AWAY FROM SAID INLET AND TOWARD SAID COALESCENT SURFACES, THE SPACING BETWEEN ADJACENT ELECTRODES DECREASES AND THE TOTAL EFFECTIVE AREA PRESENTED BY THE ELECTRODES IN A GIVEN VERTICAL CROSS SECTION INCREASES.

Claim 3
Dependent Claim
88 words
IN A PROCESS FOR REMOVING SALT FROM A LIQUID HYDROCARBON WHICH INCLUDES THE STEPS OF EMULSIFYING SAID HYDROCARBON WITH WATER AND FLOWING THE RESULTING EMULSION THROUGH AN ELECTRICAL TREATING ZONE WHERE IT IS SUBJECTED TO AN ELECTRICAL FIELD AND THEN TO A SETTLING ZONE WHEREIN SEPARATION BETWEEN WATER AND OIL IS EFFECTED, THE IMPROVEMENT WHICH COMPRISES APPLYING SAID ELECTRICAL FIELD IN SAID ELECTRICAL TREATING ZONE BY FLOWING SAID EMULSION THROUGH AN ELECTRODE ARRANGEMENT PROVIDING DECREASED ELECTRODE SPACING AND INCREASED TOTAL ELECTRODE AREA IN THE DIRECTION OF FLUID FLOW.
