Nsions ecologically acceptable method of breaking mineral oil emulsionssuspe

Abstract

Abstract A WIDE VARIETY OF MINERAL OIL (PETROLEUM) SUSPENSIONS OF THE OIL-IN-WATER, WATER-IN-OIL TYPES, PARTICULARLY THOSE CONTAINING FINELY DIVIDED SOLID SUSPENDED MATTER ARE BROKEN INTO AN ECONIMICALLY VALUABLE MINERAL OIL FRACTION LOW IN SUSPENDED SOLIDS AND WATER AND AN ECOLOGICALLY ACCEPTABLE WASTE WATER BY USING A HIGH MOLECULAR WEIGHT WATER SOLUBLE POLYELECTROLYTE, SUCH AS A POLYACCYLAMIDE, AND AT LEAST ONE SURFACE ACTING AGENT SUCH AS AN ALKYL SULFOSUCCINATE. OTHER POLYELECTROLYTES AND OTHER SURFACTANTS AND MIXTURES THEREOF ARE EFFECTIVE WITH A WIDE VARIETY OF SUCH EMULSION-SUSPENSIONS; AND RESULT IN AN ECOLOGICALLY EFFECTIVE SEPARATING PROCEDURE. THE COMBINATION OF (1) A PREFERENTIALLY WATER SOLUBLE SURFACTANT SUCH AS SODIUM ISOPROPYLNAPHTHALENE SULFONATE WHICH IS PARTICULARLY EFFECTIVE IN COALESCING WATER PARTICLES, (2) A PREFERENTIALLY OIL SOLUBLE SURFACTANT SUCH AS SODIUM DI(2ETHYLHEXYLESULFOSUCCINATE WHICH IS PARTICULARLY EFFECTIVE IN COALESCING OIL PARTICLES, AND (3) A HIGH MOLECULAR WEIGHT POLYACRYLAMIDE OF UP TO ABOUT 20 MILLION MOLECULAR WEIGHT WHICH IS PARTICULARLY EFFECTIVE IN FLOCCULATING FINELY DIVIDED SOLIDS, POTENTIATE AND SYNERGISTICALLY AID EACH OTHER AND WITH HEAT TO THIN THE OIL LAYER, IF IT IS VISCOUS, GIVES PARTICULARLY ECOLOGICAL ADVANTAGEOUS RESULTS.
