Abstract
Abstract APPARATUS AND METHOD FOR SEPARATING WATER FROM FLOWING HYDROCARBON STREAMS WHICH CONTAIN WATER EITHER AS FREE WATER OR AS A WATER EMULSION. THE INVENTION FURTHER PROVIDES A FAIL-SAFE METHOD OF OPERATION IN THAT HYDROCARBON FLOW IS TERMINATED IF THE HYDROCARBON STREAM CONTAINS WATER AFTER PASSING THROUGH THE SEPARATING APPARATUS BECAUSE THE CAPACITY FOR WATER REMOVAL HAS BEEN EXCEEDED. SUCH BENEFICIAL RESULTS OCCUR THROUGH THE USE OF A MATERIAL OR COMBINATION OF MATERIALS NORMALLY PERMITTING LIQUID HYDROCARBON FLOW BUT WHICH, IN THE PRESENCE OF WATER, FORMS A BARRIER TO INHIBIT LIQUID FLOW.
