摘要:
A method and apparatus for augmenting the coalescence of water in a water-in-oil emulsion. The apparatus includes a tubular vessel having a cylindrical side wall and opposed ends. A tangential inlet in the cylindrical side wall is adjacent one of the vessel ends. A tubular electrode having an external diameter less than the internal diameter of the vessel extends concentrically within the vessel from the one end less than the entire length of the vessel. An elongated electrode extends axially and concentrically within the tubular electrode from the one end. An outlet is provided in the one end between the tubular electrode and the elongated electrode. The inlet and outlet serve to cause fluid to initially flow through the vessel in a circumferential path outside the tubular electrode and thereafter axially through the tubular electrode to the outlet. An electrical potential is applied between the electrodes and the vessel.
摘要:
A method and apparatus of augmenting the coalescence of water in a water-in-oil emulsion in which the emulsion is tangentially ejected into the interior of a cylindrically walled vessel to cause the emulsion to flow circumferentially within the vessel and to thereby cause the water component of the emulsions to migrate towards the vessel cylindrical wall, the vessel having an axially positioned electrode therein. A voltage, preferably a pulsating DC voltage, is imposed between the electrode and the vessel to thereby subject the swirling water-in-oil emulsion to an electrical potential to cause the water components to coalescence from smaller to larger droplets. The water-in-oil emulsion is passed from the vessel where the water component can be more effectively separated from the emulsion by gravitational or centrifugal separation.

A method of augmenting the coalescence of water in an emulsion having a heavier water component that is relatively electrically conductive and a lighter oil component that is relatively non-conductive, including the steps of tangentially injecting the emulsion into the interior of a cylindrical vessel and tangentially withdrawing the emulsion from the vessel interior to cause the emulsion to flow circumferentially within the vessel to thereby impart centrifugal force on the emulsion to create a first area within the vessel adjacent the vessel sidewall in which the heavier water component of the emulsion is maintained and a second area within the vessel interior towards which the lighter oil component migrates and imposing an electrical potential on a concentrically positioned electrode within the vessel interior and thereby on the areas within the vessel having the circumferentially flowing emulsion to cause at least a portion of the water component of the emulsion to coalescence, the lighter, relatively non-electrically conductive oil component in the vessel interior first area adjacent the electrode permitting a higher voltage potential to be imported on the electrode.

A gas burner is provided for use on the inlet end of a fire tube, and includes a mixer having attached to it a gas delivery pipe, fuel gas and air being combined in the mixer to provide mixed gas and air. A venturi is secured at its inlet end to the mixer to receive the flow of gas and air, the venturi serving to draw air into the mixer. A burner nozzle is affixed to the venturi outlet end and the burner nozzle and extends within the fire tube. A perforated tube surrounds the mixer/venturi and at least a portion of the burner nozzle. A sound absorbing flame cell housing surrounds the perforated tube. A flame arrestor closes an air inlet opening in the flame cell housing air and serves to permit air to pass into the flame cell housing but prohibits the passage of flame therethrough so that flame is confined within the interior of the flame cell housing. A sound absorbing flame arrestor cover is supported exteriorly of the flame cell housing and adjacent the flame arrestor and configured to permit free passage of air into the flame cell housing through the flame arrestor but prohibiting straight line passage of sound through the flame arrestor from the interior to the exterior of the flame cell housing.
摘要:
A method for processing interface emulsion, water, and solids contained within a separator vessel that comprises the steps of continually extracting those components from the vessel and then passing them through a gas flotation cell. The cell, which is preferably a vertical induced gas flotation cell, separates the oil and water contained in the interface emulsion and discharges recovered oil from an upper portion of the cell and treated water from a bottom portion of the cell. The recovered oil and treated water may be further processed and recycled to the vessel or sent elsewhere. The treated water may also be recycled to the cell or sent to a process sewer. Fuel gas residing in an upper portion of the cell may be cooled and passed through a splitter. All the steps of the method comprise a closed system with no air emissions.
摘要:
An apparatus and method for separating water from an oil-and-water mixture includes at least two elongated separator vessels oriented at an incline and connected to one another so that an upwardly flowing oil predominant fluid passes from the first separator vessel to the second separator vessel where further electrostatic separation of water from the oil predominant fluid occurs. Each vessel has an electrode at its upper end preferably connected to a different voltage source. The inlet to each vessel is located relative to the electrode to provide an up flow or a down flow vessel. Additionally, the first vessel may be at a different elevation than the second vessel. An additional vessel may be included with output from the first vessel bypassing the additional vessel, the second vessel, or both. Baffles may be added in the water collection portion of each vessel to reduce turbulence and settling distance.

摘要:
An apparatus for separating water from a water-in-oil mixture having an elongated inlet vessel with a lower outlet end and an upper inlet end, the length thereof being a multiple of the largest vessel cross-sectional dimension. A separation vessel having an oil outlet and a divergent water outlet has an inlet passageway in communication with the inlet vessel lower outlet end. At least one electrode is positioned within the inlet vessel by which a mixture flowing therethrough is subjected to an electric field.

A method of separating gaseous components, heavier liquid components and lighter liquid components of a stream including the steps of conducting the stream between spaced apart electrodes in a treatment vessel, supplying from a voltage source an AC voltage of at least one base frequency F1 to at least one of the electrodes to establish an electric field within the vessel through which the stream passes, modulating the frequency F1 of the AC voltage at a modulation frequency F2, and withdrawing separated gaseous components from an upper portion of the vessel, heavier stream components from a lower portion of the vessel, and lighter liquid components from an intermediate portion of said vessel.
