Method and apparatus for hydrocyclone

BACKGROUND

One embodiment relates generally to systems and methods for utilizing a modular hydrocyclone, also known as a cyclone centrifuge, apparatus for addressing separation or classification of items such as sand from fluids, including drilling, fracturing (frac) and completion fluids, used in oil and gas operations, that can deal with different ranges of fluid flows and characteristics.

Traditional hydrocyclones have tangential entry of the flow causing greater wear and the entire or complete hydrocyclone requires replacement where erosive wear occurs.

The current sand/solids separators have been proven not to be efficient. Traditional hydrocyclones are designed for a narrow range of flow characteristics. If the flow falls outside the design range, a second complete hydrocyclone unit would need to replace the first hydrocyclone unit, where the second hydrocyclone unit was designed to accommodate the different flow.

There is a need to provide the ability to replace in field one or more components of the modular hydrocyclone to address various flow characteristics without the need of replacing the hydrocyclone body or pressure vessel that the hydrocyclone body is attached.

There is a need to provide the ability to replace in field one or more components of the modular hydrocyclone to address where erosive wear occurs without the need of replacing the hydrocyclone body or pressure vessel that the hydrocyclone body is attached. There is a need to provide the ability to have the flow entering the modular hydrocylone in a direction that generally intersects the longitudinal axis of the cone instead of tangentially entering the cone.

While certain novel features of this invention shown and described below are pointed out in the annexed claims, the invention is not intended to be limited to the details specified, since a person of ordinary skill in the relevant art will understand that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation may be made without departing in any way from the spirit of the present invention. No feature of the invention is critical or essential unless it is expressly stated as being “critical” or “essential.”

Conditioning of Flow

In various embodiments of the modular/variable hydrocyclone system 500, the flow into the interior 650 of the hydrocyclone body 600 is “conditioned” by the hydrocyclone insert 1000 and lower conical tube by entering

(a) first axially in the direction of arrow 690 generally intersecting the longitudinal axis 660 of the interior bore 650 of body 600 and

(b) then spiraled by a helical channel 1100 in hydrocyclone insert 1000

- (e.g., arrows 692,693 via helical channel 1100)
  - (spiral flow pathway of helical channel 1100 created by upper wall 1110, lower wall 1120, rear wall 1140, and interior surface 1140)
    
    that conditions the flow from axially directed to tangentially directed
    
    creating centrifugal forces in the flow
    
    thereby separating items contained in the flow having different densities
    
    (e.g., one flow path exiting body 600 via arrow 696 and
    
    a second path exiting body 600 via arrow 694),
    
    such as separating the liquid and or gas stream portions of the flow
    
    from the solids contained in the flow.

As shown in FIGS. 1-3, 9-14, 29, and 43, the modular design incorporates:

(a) a fixed head or hydrocyclone body 600 installed on top of a pressure vessel 200 that allows the hydrocyclone body 600 to have

(b) affixed within the head 600 and removable

- a hydrocyclone insert 1000 having a helical flow pathway/channel 1100; and
- a lower conical tube combination (1500,1600).

The hydrocyclone insert 1000 having a helical flow pathway/channel 1100 allows the flow to enter the hydrocylone “axially” (i.e., in the direction of arrow 690 generally intersecting longitudinal centerline 660 of the interior bore 650 of hydrocyclone body 600) instead of tangentially (i.e., at the sidewall 652 of interior 650 of body 600).

Modular Options and Variable Hydrocyclone

In various embodiments is provided the method of keeping body 600 while switching out a first hydrocyclone insert 1000 and/or its associated upper tube and/or lower conical tube with a second hydrocyclone insert 1000′ of and associated upper tube and/or lower conical tube while keeping original body 600. Such embodiment saves funds as body 600 is the pressure rated piece of modular/variable hydrocyclone system 500. In these embodiments, the hydrocyclone inserts and/or their associated upper tube and/or lower conical tubes are treated as wear replaceable parts preventing wear or failure of body 600. In various embodiments is provided the method of keeping body 600 while switching out a first hydrocyclone insert 1000 and/or its associated upper tube and/or lower conical tube with a second hydrocyclone insert 2000 and its associated upper tube and/or lower conical tube (e.g., 3500) where second hydrocyclone insert 2000 and its associated upper tube 2500 and/or lower conical portion 2700 are substantially different from first hydrocyclone insert 2000 and its associated upper tube and/or lower. Such embodiment allows modular/variable hydrocyclone system 500 to address substantially different fluid systems while not having to replace body 600.

The method and apparatus of utilizing a modular and variable hydrocyclone 500 on a pressure vessel 100 for well flow back, well cleanup and fracking operations. The invention utilizes a changeable and replaceable hydrocyclone insert comprising a hydrocyclone insert 1000 having a helical flow pathway/channel 1100, and a lower conical tube combination including first insert 1000 and second insert 2000 that can be replaced for various sizes and flow characteristics without replacing the head 600 and the pressure vessel 200.

For example, FIGS. 33-42 and 47-55 show alternative hydrocyclone insert 2000 combinations having a smaller diameter helical flow pathway/channel 2100 with alternative insert 2000 along with a smaller (e.g., a 2 inch) flow exit opening both at flow arrow 654 and at flow bore 2040). While using the same head 600 upper exit 700 and entrance 800, the flow handling characteristics of modular/variable hydrocyclone system 500 using the same body can be changed by switching from insert 1000/lower conical tube combination (1500,1600) to insert 2000/lower conical tube 3500 or lower conical tube combination 2500,2700. Alternatively, insert 1000/lower conical tube combination (1500,1600) can be switched out for insert 2000/lower conical tube 3600 or lower conical tube combination 2500,2700.

In FIG. 33, with alternative hydrocyclone insert 2000, the flow schematically indicated by arrow 692′ is conditioned by entering axially and then spiraled by a helical flow pathway/channel 2100 from being directed to intersecting the longitudinal centerline 660 to flow that is “tangential” to the side wall 3548 of conical tube 3500 to create centrifugal forces, and thus separating the solid from the liquid and or gas stream.

The flow enters the hydrocyclone body 600 directed towards the longitudinal centerline 660 instead of tangentially along a sidewall as in prior art hydrocyclones. This is schematically represented in FIGS. 7 and 8 by arrow 690 and centerline 631 intersecting with longitudinal centerline 660 (schematically indicated by “X”). The hydrocyclone inserts 1000 or 2000 with their helical pathway condition the flow to be tangential and initiates the centrifugal flow. The hydrocyclone insert 1000 or 2000 with its respective conical tube combination (1500,1600)/conical tube 3500 can be replaced in the event of flow characteristics changing or damage/wear without replacing the hydrocycone body 600 or head.

(a) The insert 1000,2000 may be removable from the head 600 without changing or damaging head 600.

(b) The head 600 may be on top of the pressure vessel 200 or contained within the pressure vessel 200.
