Abstract:

A cyclone apparatus for separating a mixture containing at least one fluid and a further constituent based on the densities of the mixture constituents. The apparatus includes a first hollow pressure vessel having an overflow plate positioned at an overflow end of the first hollow pressure vessel and an end plate for sealing the overflow plate. The cyclone apparatus also comprises an underflow plate positioned at an under-flow end of the first hollow pressure vessel and a hollow pressure vessel with one end being sealed against the under-flow plate and another end being closed. The overflow plate and the end plate are shaped such that when they are brought together they form separate adjacent overflow compartments between them. The underflow plate and the second hollow pressure vessel are shaped such that when they are brought together they form separate adjacent under-flow compartments between them which correspond to the overflow compartments.

Appl. No.:

13/280507

Inventors:

Mark E. Wolf - Katy TX, US

International Classification:

B01D 17/038
B04C 5/00
C02F 1/38

US Classification:

210787, 2105121

Abstract:

A separator system and method are provided in which the separator has two outlets for different components of mixed fluid. An energy harvester is provided on one of the outlets, wherein harvested energy is transferred to a pump located on an inlet of the separator. As a result, the differential pressure across the separator is increased.

Abstract:

A method of controlling a hydrocyclone system for separating a fluid mixture wherein the system includes a separator vessel for receiving the fluid mixture and performing a primary separation of the more dense and the less dense fluid phase thereby forming an interface within the separator, and a hydrocyclone apparatus having a first and second hydrocyclone compartments to separate the phases. The method includes alternating the flow rate through the hydrocyclone apparatus, alternating the interface or fluid mixture level in the separator vessel between a first level and a second level; and alternating the second hydrocyclone compartment between an open state in flow communication with the first hydrocyclone compartment and a closed state in isolation from the first compartment.

Abstract:

A fluid separation apparatus includes a hydrocyclone () having an orifice () therein, a housing () disposed in the hydrocyclone and having a bore (), a piston () disposed in the bore () of the housing (), and a first annular seal () disposed between the housing () and the piston () and configured to restrict fluid communication between the housing () and the piston (), wherein the piston () includes a passage () extending through the piston () and having a pin () coupled to a first end () of the piston, the piston () being actuatable to move between a first position () where the pin () is clear of the orifice () of the hydrocyclone, and a second position where the pin () is disposed in the orifice (), wherein, the piston () is configured such that as the piston is actuated from the first position to the second position, fluid is permitted to flow into the passage () of the piston () from the bore () of the housing ().

International Classification:

B01D 17/02
B01D 17/12

Abstract:

A system and method for extracting oil from a fluid mixture includes a separation vessel having an internal chamber that extends to a chamber elevation, an inlet port, a water outlet port, and an oil outlet port. A liquid storage tank has an inlet port, an upper outlet port located at an upper outlet elevation, and a lower outlet port. A first conduit system interconnects the separation vessel's water outlet port and the tank's inlet port and has a top conduit segment at the upper outlet elevation. A second conduit system interconnects the first conduit system and the tank's inlet port. The second conduit system intersects the first conduit system below the upper outlet elevation and above the chamber elevation. A pump may be employed to transfer fluid from the upper outlet port back to the separation vessel.

International Classification:

B04C 11/00

US Classification:

210787, 2105121, 210251

Abstract:

A fluid treatment system, a fluid processing apparatus and a method of treating a mixture are provided in which a separator has two outlets for different components of mixed fluid. A conduit connecting one of the outlets of the separator to the inlet of the separator is provided to recycle fluid from an outlet of the separator back to the inlet and a pump at the inlet of the separator regulates the fluid flow through the separator at a constant rate. As a result, the flow rate through the separator is increased, which increases the separation efficiency of the separation system. The conduit also functions as a bypass line should the flow of fluid be obstructed through the separator. The conduit may preferably be operated in conjunction with an energy harvester.
