摘要： The present invention relates to the use of alkoxylated polyglycerols preparable by polycondensation of glycerol and subsequent alkoxylation for demulsifying water-oil emulsions, in particular in the production of crude oil from crude oil/water emulsions. The invention provides for the use of alkoxylated polyglycerols with a molecular weight of from 250 to 100,000 units which comprise 2 to 100 glycerol units whose free OH groups are alkoxylated with C2–C4-alkylene oxide groups or a mixture of such alkylene oxide groups so that the alkoxylated polyglycerol has a degree of alkoxylation of from 1 to 100 alkylene oxide units per free OH group. The alkoxylated polyglycerols of the present invention are employed for demulsifying oil/water emulsions in amounts of from 0.0001 to 5% by weight, based on the oil content of the emulsion to be demulsified.

摘要： Fluids viscosified with viscoelastic surfactants (VESs) may have their viscosities reduced (gels broken) by the direct or indirect action of a composition that contains at least one metal ion source and optionally at least one second source. An optional second source may be a chelating agent where at least one reducing agent source may be additionally optionally used. Another optional component with the metal ion source includes a second, different metal ion source. The breaking composition is believed to directly attack the VES itself, possibly by disaggregating or otherwise attacking the micellar structure of the VES-gelled fluid, and/or possibly by changing the chemical structure of the VES to give two or more products.

摘要： The present invention relates to a stable emulsion of an immiscible fluid and of an aqueous phase having a determined pH value. The emulsion is optimized in that it comprises an ionic surfactant and a polyampholytic polymer whose charge depends on the pH value. The respective amounts of surfactant and of polymers are determined according to the charges. Stabilization or destabilization of the emulsion is adjusted by controlling the pH value. The invention also relates to a method of stabilizing and destabilizing an emulsion comprising a surfactant combined with an ampholytic polymer.

摘要： The system for treating effluent water coming out from the desalter in accordance with the present invention comprises a slop oil separator 1 for removing oil components in the effluent water from the desalter; a WSR separator 2 for further removing emulsion type oil components using naphtha; a water stripper 4 for removing gas components such as H.sub.2 S and NH.sub.3 in the effluent water discharged from the WSR separator; a reaction tank 5 for reacting organic and/or inorganic impurity matters such as phenols and suspended solids in the effluent water discharged from the water stripper with activated charcoal; and a settling tank 6 in which an agglomerating agent is introduced, thereby precipitating sludge in the lower part of the settling tank. A buffering tank 3 may be installed between a desalter (not shown in FIG. 1) and an oil separator 1 or between a WSR separator 2 and a water stripper 4 to play a role as a buffer for safety in case of an accident in the process. Activated charcoal is introduced into the reaction tank 5. An agitator 14 is installed to mix physically the effluent water containing activated charcoal in the reaction tank. Alternatively, an air supply device 15 is installed to mix the effluent water containing an activated charcoal by supplying air into the reaction tank.

摘要： A nonionic surfactant having cyclic 1,3-dioxane and/or 1,3-dioxolane functionality which is irreversibly splittable by lowering the pH of its aqueous solution is useful in various processes requiring the removal of emulsified hydrophobic contaminants or other hydrophobic materials from an aqueous stream. After splitting of the surfactant into its component aldehyde and polyol, the hydrophobic components phase-separate and can be removed from the aqueous stream by routine means.

The method comprises the steps of mixing with the wash water, either alone or in combination, about 30-2100 ppm of a surfactant having the formula: ##STR1## where n is 6-20; and about 1-200 ppm of an enzyme selected from the group consisting of proteases, amylases, lipases, cellulases, pectinases and mixtures thereof. The mixture of wash water surfactant and/or enzyme is then permitted to stand for a time sufficient for the oleophilic-hydrophobic material to separate.
