СOMPOSITE DEMULSIFIER FOR THE PREPARATION OF HEAVY HIGH-VISCOSITY OILS

During laboratory tests of oil-water emulsion from the Penjachinsky fieldofJSCElabuganeft,highlyeffectivemultifunctioncompositeemulsionbreakerSTH-DP-11М was designed taking into account crude-oil emulsion properties. As a result of fieldtestsithasbeendetermined,thatattheexpenseofappearance of a synergism of the action of different components of the designed composite, substitution of basic compounds on STH-DP-11М allowed to stabilize water content and salt content in oil-water sludge entering oil treatment unit, and also to meliorate quality of commercial water. Application of the produced compound provides indicators of water and salt content in tank oil according to requirements of GOST.
