    摘要: A method for breaking an emulsion comprising oil and water into oil and water phases comprising treating the emulsion with a chemical demulsifier and passing the mixture through a hollow chamber having a uniform cross-section and subjecting the mixture to acoustic energy in the frequency range of about 0.5 to 10.0 kHz, preferably 1.25 kHz, to enhance breaking the emulsion into a water phase and oil phase. The oil phase is then separated from the water phase by gravity separation and recovered. The sonic energy is generated by a transducer attached to the mid-section of the upper or lower outer surface of the hollow chamber. For emulsions containing light oil having an API gravity greater than 20 and water, the emulsion can be broken by the use of acoustic energy in the frequency range of about 0.5 to 10.0 kHz without the addition of chemical demulsifiers.

    摘要: A process for separating vaporous mixtures of hydrocarbons, water and emulsifier derived from the remediation of wellbore fluid, such as a mud containing solid particulate material in which the vaporous mixture is quenched with a hydrocarbon stream which is at a temperature above the boiling point of water and below the boiling point of the hydrocarbons in the vaporous stream. Most of the hydrocarbons in the vaporous stream and substantially all of the emulsifier are condensed into the hydrocarbon quench to form an oil stream. The water is recovered from the hydrocarbon quench as a vaporous stream and quenched with water. The quenched water and any residual heavier hydrocarbons are separated by phase separation.

    摘要: Oil-in-water (reverse) and water-in-oil (obverse) emulsions in crude oil production and processing systems are resolved by addition of a treatment solution comprising a copolymer of acryloxyethyltrimethyl ammonium chloride (AETAC) and acrylamide. The mole percent of AETAC is above about 20% and the molecular weight (grams per mole) of the copolymer is above about 2 million. The treatment solution is effective in matrix which include high percentages of oil and at high temperatures.

    摘要: Polymer compositions made by reacting a polyol with an aromatic hydrocarbon containing only a single reactive functionality have been discovered to be useful demulsifiers for crude oil compositions. The aromatic hydrocarbon should have at least one aryl group and only one functionality reactive with a hydroxyl. The polyol may optionally be crosslinked prior to reaction with the aromatic hydrocarbon, and the crosslinking agent may be a diepoxide.

    摘要: A method for dehydrating a liquid/liquid production stream which is comprised of a heavy crude oil (i.e. about 30.degree. A.P.I. or less) and water which originally forms a water-in-oil emulsion wherein hydrocyclone is used as a primary separator to separate substantial amounts of the water from the stream. The stream is first treated without chemicals to sustantially alter of its characteristics by either (a) heating the stream to substantially reduce the viscosity of the heavy crude therein and/or (b) inverting the emulsion in the stream to an oil-in-water emulsion. Once the characteristics of the stream are so altered, the stream is passed through the primary hydrocyclone to separate out a significant amount (e.g. about 50% or more) of the water. The stream is then passed either to a second hydrocyclone or a stablization tower to separate additional water from the oil and bring it within shipping and/or sale specifications.

    摘要: This invention provides a process for preparing novel hydrophobically associating polymers containing cationic functionality which are useful for clean-up of waste waters containing organic contaminants. These water soluble polymers contain both water soluble and water insoluble monomers. The water soluble monomers are acrylamide (AM) and a salt of an unsaturated amine base (C), and the water insoluble monomer is a higher alkyl(meth)acrylamide or alkyl(meth)acrylate (R). These polymers are referred to as CRAM. The process relies on the dissolution of the water insoluble monomer(s) into an aqueous solution of water soluble monomers by means of a water miscible mutual cosolvent. The type and concentration of miscible solvents are chosen to produce a clear, uniform, homogeneous aqueous solution of the hydrophobic monomers in the presence of both nonionic and cationic water soluble monomers and, in addition, the reaction medium remains a clear, uniform, homogeneous mixture with no phase separation as the reaction proceeds to completion. Redox or free radical initiators are used to copolymerize both the water soluble and water insoluble monomers, forming terpolymers of ethylenically unsaturated amine base salts, alkyl(meth)acrylamides of alkyl(meth)acrylates and acrylamide. These polymers provide exceptional clean-up of waste waters containing organic contaminants. Also they are very effective for resolving oil-in-water emulsion, as such as those found in oil production.
