Abstract

WATER IN CRUDE OIL EMULSIONS ARE USUALLY FORMED DURING PETROLEUM PRODUCTION AND ASPHALTENES PLAY AN IMPORTANT ROLE IN THEIR STABILIZATION. DEMULSIFIERS ARE ADDED TO DESTABILIZE SUCH EMULSIONS, AND ARE SOMETIMES COMBINED TO OTHER MECHANISMS LIKE MECHANICAL, ELECTRICAL AND THERMAL TECHNIQUES TO EASE WATER/CRUDE OIL SEPARATION. DEMULSIFIERS BREAK EMULSIONS DUE TO DECREASING INTERFACIAL TENSION (IFT) BETWEEN OIL AND WATER. IN THIS STUDY ORGANO MODIFIED NANO-SIZED POLYSILOXANES ARE BUILT THROUGH SOL-GEL METHOD. THEY CAN BE USED AS STAND-ALONE DEMULSIFIERS OR AS ADDITIVES TO ORGANIC BASED DEMULSIFIERS. EXPERIMENTS SHOW THAT THE PERFORMANCE OF THE DESIGNED DEMULSIFIERS IN SEPARATING WATER FROM CRUDE OIL EMULSION IS MUCH BETTER THAN THE CONVENTIONAL DEMULSIFIERS SUCH AS EO/PO CO-POLYMERS, AMINES, ALKYL PHENOL FORMALDEHYDE RESIN AND ETC.THE STRONG SEPARATION ABILITY COMES FROM THE SILICONE NETWORK AND IT’S GREATER TENDENCY TO LOWERING THE IFT, AND THE SIZE OF SURFACTANT.IT IS KNOWN THAT SMALLER SURFACTANTS DECREASE IFT MORE THAN BIGGER ONES. THE SURFACTANT SIZE IS CONTROLLED BY THE SILICONE NETWORK SIZE. HYDROPHILIC LIPOPHILIC BALANCE (HLB) AND OTHER IMPORTANT PARAMETERS OF DEMULSIFIER ARE CONTROLLED BY THE SIZE OF SILICONE NETWORK AND POLYMER TO SILOXANE RATIO. THE ORGANO MODIFIED NANO-SIZED POLYSILOXANE DEMULSIFIERS SHOW MORE FLEXIBILITY TO USE FOR DIFFERENT WATER/CRUDE OIL EMULSIONS FROM DIFFERENT OIL FIELDS AND GREAT MIGRATION POWER IN EMULSION SYSTEMS.
