Apparatus for handling and preparing fluids

BACKGROUND OF THE INVENTION

The ability to mix various materials with fluids on a continuous high volume basis has been a goal in various industries for many years. The oil and gas drilling industry, for example, mixes large quantities of drilling fluid for downhole circulation during drilling. Such fluids are both water and oil based, and the materials added are varied, such as bentonite, barite, polymers, and many other liquids and powders. Other applications include a number of industries involving polymer mixing, water treatment, slurry walls, clay slurries, lime slurries, solubilizing dry chemicals, and horizontal drilling for industrial applications, such as river crossings.

Devices commonly utilized for such purposes, particularly in the oil and gas drilling industry, an eductor assembly generally, and a particular adaptation of an eductor assembly known as a venturi hopper, of the type having a base fluid inlet, a material funnel for feeding materials, a substantially vertical hopper throat, a hopper throat valve, and an eductor, having a mixing chamber, a jet, and a venturi discharge/diffuser which receives and discharges the jetted fluid, along with the materials drawn from the hopper throat into the jetted fluid by the venturi effect. Also utilized are low velocity shearing devices, which create turbulence in the fluid by moving the fluid through low shear plates and/or static mixers, as well as, high velocity shearing devices which typically involve dividing the fluid into two flows, then rejoining the flows in opposition to each other, the interaction causing beneficial impact and turbulence. The high velocity shearing devices typically involve jetting the fluid for additional turbulence.

The above devices have been combined into various systems, but such systems suffer from a lack of routing options among the devices, ineffective methods for adding special chemical powders, such as powdered polymers, ineffective secondary materials feed inlets in addition to the primary material funnel feed, a lack of routing for effective backflowing of the shearing devices, a failure to combine both the low and high velocity shearing devices, cumbersome service access to the jet, ineffective use of available space on location, and/or redundant power sources.

An example is U.S. Pat. No. 5,765,946 which provides a continuous static mixing apparatus and process which includes an eductor assembly, at least one “mixing disk,” which create turbulence, and routing for the interaction of opposing flows. The processes which both the eductor and the mixing disks, include the base fluid entering either the eductor or the mixing disks first, then the other in series. No other routings are shown for the combined devices. The drawings do not depict alternate routings for an individual embodiment, nor is a routing suggested for backflowing through the mixing disks. More than one materials entry point into the eductor assembly is generally suggested, although the eductor assembly actually shown includes what appears to be a hopper throat only.

U.S. Pat. No. 5,322,222 discloses a spiral jet mixer for mixing fluids, which has a first inlet nozzle for the introduction of a primary fluid, a mixing chamber having a diverging wall and a converging wall, a plurality of angled helical passageways in the diverging wall for introduction of a secondary fluid into the mixing chamber in a spiraling turbulent, initially convergent flow pattern. The device is marketed by VORTEX VENTURES, INC., and is referred to as a radial eductor.

Another example is the LOBESTAR™ Mixing Eductor by VORTEX VENTURES, INC., includes a typical venturi hopper, modified to provide a “radial premixer,” which has an inner liner within the throat, through which a substantial portion of the base fluid is routed, the base fluid being tangentially directed through the liner to create a vortex, the materials from the hopper being premixed, to some extent, with this portion of the base fluid, as the material is drawn into the eye of such vortex. The base fluid entry into the hopper throat is substantially lower than the hopper throat valve. Also included is a small “vacuum gauge and chemical injection inlet” which discharges into the mixing chamber. This device diverts an unacceptably large amount of the base fluid from the jet, requiring a lower amount of jetted fluid to draw a larger amount of“pre-mixed” base fluid and materials into the venturi discharge. The device also allows a vacuum to be created against a closed hopper valve, in cases where the “chemical injection inlet” is the sole source of materials. Such a vacuum is undesirable in that accumulations of materials can be created when partially wetted materials are drawn into the hopper throat area beneath the hopper throat valve. Similarly, the “chemical injection inlet” is too small to use for the introduction of powdered chemicals, and is impractical for use in applications in which this inlet is the sole source of materials being added to the base fluid. This impracticality is made worse by the reduction in vacuum caused by the routing of a substantial amount of fluid through the radial premixer. An additional problem is the ineffective access to the jet for replacement.

Another example is the SHEAR TEARER™ In-Line Shearing device, which provides a low velocity shearing device to be combined with a venturi hopper, in parallel only, with no high velocity shearing device, and no routing option for using the devices in series, no routing option system bypass, and no routing option for backflowing the fluid through the shearing device.

An additional example is the JET SHEART™ II, continuous mixing system by Flo Trend™ Systems, Inc., which includes a venturi hopper in series with two shearing devices, with a routing option to bypass the shearing devices, but not the venturi hopper. No routing option is provided for backflowing through the shearing device, and no low speed-shearing device is provided.

Similar to this device is the JET SHEAR™ manufactured by Flow Process Technologies [S] Pte. Ltd., in which the primary difference is the orientation of the fluid recombination path in the shearing device, changing from an angled recombination to an inline recombination of the fluid. The entering liquid is divided into two equal and opposing streams through a yoke assembly. These streams are directed into a mixing chamber through discs containing nozzles located in each end of the mixing chamber, which form the lateral boundaries of the mixing chamber. These nozzle plates are positioned to oppose each other. The nozzles contained in these respective plates are equally spaced on a circle located near the outer perimeter of the nozzle plates and are precisely angled with respect to the horizontal and vertical planes of the mixing chamber. The nozzles are identical in both plates, and since these plates are geometrically opposed, the liquid streams directed through each nozzle plate are moving in opposite rotational directions, one clockwise and one counterclockwise. Product literature suggests installing the device in parallel with the drilling rig mixing hopper.

U.S. Pat. No. 4,664,528 discloses an apparatus and method for mixing water in a water-soluble emulsion polymer, which includes a pump means, a static mixing means, and a mixing chamber means, where a first circulation means connects the pump means to the mixing chamber means, a second circulation means connects the pump means to the static mixing means, and further connects the static mixing means to the mixing chamber means. A third circulation means connects the static mixing means to the mixing chamber means. Flow control means selectively circulates the combined stream of the water and the polymer alternatively through the first circulation means, the second circulation means, or the third circulation means. The pump means has an inlet adapted to receive and combine the water and the emulsion polymer to form a combined stream of water and emulsion polymer. The apparatus has a static mixing means for mixing water and polymer, having an inlet adapted to receive and combine the water and the emulsion polymer to form the combined stream. The mixing chamber means produces a homoceneous mixture of the water and emulsion polymer.

A typical venturi hopper is the Phoenix Solids Control Systems device by Harrisburg/Woolley. In at least one device, Harrisburg/Woolley has utilized the mixing chamber suction by running a line from the mixing chamber to the top of the material funnel for the purpose of vacuuming “dust” generated during the addition of bulk materials, such as bentonite.

The SECO SUPER SHEAR™ by ITS Drilling Services is a variable speed-shearing device, which is installed either downstream or upstream of the rig-mixing hopper. It utilizes a SECO HOMOGENIZER, which is a field version of a colloid mill, and requires an electric motor. ITS Drilling Services also provides the POLYGATOR™ SHEARING SYSTEM, which also uses a SECO HOMOGENIZER.

The Geolograph-Pioneer SIDEWINDER™ uses two-stage cyclonic action which hydrates, mixes and blends mud additive particles to uniformity before discharge into the mud system. In this device the liquid is routed behind a liner in such a manner as to create a vortex into which dry bulk materials are fed prior to discharge of the liquid from the device.

DETAILED DESCRIPTION

An example embodiment of our invention

30

is depicted in

FIGS. 1-7

b

, wherein an inlet

32

, an outlet

34

, a materials addition device

36

and a combination first shearing device

38

and second shearing device

40

are cooperatively interconnected by a first conduit branch

42

, second conduit branch

44

, and third conduit branch

46

, the first, second and third conduit branches

42

,

44

,

46

having both pipe sections

50

a-j

, materials addition device flanges

52

a-b

, victaulic connections

54

a-d

, valves

56

a-j

, and valve flanges

57

. In this example embodiment the pipe

50

is six inch Schedule 40 steel. The valves

56

a-j

are six inch internal diameter butterfly valves, with oil resistant trim, mounted between six inch slip on flanges

57

with ANSI rating of 150 psi. The flange

52

b

in the material addition device

36

is a six inch slip on blind flange, bored to receive a three inch pipe section

53

. This three inch pipe section

53

is Schedule 80 steel. The remainder of flange

52

b

is a six inch slip on flange. The victaulic connections

54

a-b

are either three inch or six inch internal diameter style 77 victaulic clamps.

The materials addition device

36

in this example embodiment is a particular type of an eductor assembly known as a venturi hopper

70

wherein materials can be added through a material funnel

72

, the materials descending from the material funnel

72

hopper through a hopper throat

74

and hopper throat valve

56

b

, into a mixing chamber

76

. Fluid entering the materials addition device

36

,

70

is jetted by a replaceable jet

78

, which jets the fluid through the mixing chamber

76

into a venturi discharge

80

. The mixing chamber

76

is eight inch Schedule 40 steel, with both ends reduced to six inches for connection to flanges

52

a-b

. The replaceable two inch jet

78

and the venturi discharge

80

are 4140 high tensile steel. The jet

78

screws into the three inch pipe section

53

. The six inch pipe section

50

a

reduces to the three inch pipe section

53

.

It is anticipated that this embodiment will efficiently handle fluid entry rates of approximately 600 to 1000 gallons per minute of water, depending on the choice of high shear or low shear options. For higher or lower rates, it is anticipated that a proportionately resized jet

78

and pipe sections

50

a-j

will allow proportionately equivalent rates. For example, it is anticipated that a four inch piping arrangement, using a one and one-half inch jet would efficiently handle fluid entry rates of approximately 400 to 650 gallons per minute of water. This embodiment is also anticipated to perform efficiently with fluid pumps delivering 85 to 120 feet of head, based on fresh water.

In this example embodiment, materials may also be added through a vacuum inlet

82

, which is positioned to discharge materials into the mixing chamber

76

. Materials are routed to the vacuum inlet

82

through a vacuum inlet line

84

, which has a vacuum inlet line check valve

85

, a vacuum inlet line ball valve

86

, and a detachable vacuum inlet

88

, on the upstream side of the vacuum inlet line valve

86

. The vacuum inlet

82

and vacuum inlet line

84

are sized to receive both liquid and powder materials, in sufficient volumes, to enable high volumes of jetted fluid to receive appropriate amounts of the materials. As discussed above, the jetted fluid rate can be estimated to be between 600 to 1000 gallons per minute, requiring, in many cases, that the vacuum inlet

82

discharge powdered polymers at rates of approximately 50 pounds per minute. Accordingly, it is anticipated that a vacuum inlet

82

having an internal diameter of one and one-half inches will be sufficient. Because the material primarily enters the mixing chamber

76

through vacuum inlet

82

as a result of the vacuum generated by the jetted fluid, the rate of material entry can be regulated by modifying the jetted fluid rate. In an alternate embodiment (not shown), a one and one-half inch diaphragm valve is substituted for the one and one-half inch vacuum inlet line ball valve

86

, which provides additional regulation of the rate of material entry through the vacuum inlet

82

.

In this example embodiment, the fluid can also enter the hopper throat

74

, through a throat inlet

90

positioned between the hopper throat valve

56

b

and the mixing chamber

76

. A small amount of the fluid, of approximately 12 to 15 gallons per minute is routed from the inlet

32

area to the throat inlet

90

, through throat inlet line

92

. In this example embodiment, the throat inlet

90

is positioned such that the fluid enters the hopper throat

74

tangentially to its inside circumference, as shown in FIG.

4

. The throat inlet line

92

has a throat inlet line valve

94

, and a “T” connection

96

whereby a fluid inspection line

98

can receive a portion of the fluid for discharge through fluid inspection line valve

100

. The throat inlet

90

has an internal diameter of approximately three-fourths inch, as well as the throat inlet line

92

, the “T” connection, the fluid inspection line

98

, the throat inlet line valve

94

and the fluid inspection line valve

100

, such valve

94

,

100

being rated at 150 psi. In this example embodiment, the fluid is routed through the throat inlet line

92

from the same source of the fluid, although other sources are present in alternate embodiments (not shown), in accordance with our invention, as will occur to persons of skill in the art upon review of the present disclosure.

The respective positioning of the throat inlet

90

and the vacuum inlet

82

allows the fluid to enter the hopper throat

74

above the vacuum inlet

82

. When the hopper throat valve

56

b

is closed and the fluid is being jetted, an undesirable vacuum can form in the hopper throat

74

in the area above the vacuum inlet

82

, while the vacuum inlet

82

is discharging materials to be drawn into the fluid. This can cause undesirable accumulations of materials in the hopper throat

74

when partially wetted materials are drawn into the area above the vacuum inlet

82

. Pressured fluid entry through the throat inlet

90

substantially eliminates this vacuum.

With further regard to the foregoing example embodiment, service and inspection access is provided to the replaceable jet

78

, by a detachable side inspection plate

102

, which is attached by bolts

104

. In an alternate embodiment (not shown), the vacuum inlet

82

can be positioned on the side inspection plate

102

.

A conventional venturi hopper (not shown), having no vacuum inlet, no throat inlet, and no side inspection plate, is present in other embodiments, as well as other material addition devices, in accordance with our invention, as will occur to those of skill in the art upon review of the present disclosure.

The combination shearing device

38

,

40

in this example embodiment comprises a first shearing device

38

, which further comprises pipe sections

110

a-b

. Jet inserts

112

a-b

are also provided, and are shown more fully in FIGS.

1

,

5

a-d

. Each jet insert

112

a-b

is placed near the discharge end of each pipe section

110

a-b

, each jet insert

112

a-b

being approximately three and one-sixteenth inches in diameter, and each having four tapered bores

114

a-d

leading to the point of discharge. The bores are each tapered from approximately one and one-half inch diameters to one-half inch diameters. The jet inserts

112

a-b

are made of 4140 steel, but other materials, such as high density polyurethane, made be substituted, in accordance with our invention, as will occur to those of skill in the art upon review of the present disclosure. Within each pipe section

110

a-b

, is attached a jet insert seat ring

111

a-b

, as shown in

FIG. 5

d

. This ring

111

a-b

is approximately three-fourths of an inch in depth and has a straight then tapered internal diameter from approximately 2.75 inches to 2.674 inches. The ring

111

a-b

is secured by welds

113

a-b

, and is configured such that each jet insert

112

a-b

abuts the ring

111

a-b

when inserted in the pipe sections

110

a-b

. Each jet insert

112

a-b

is sealably positioned within the pipe sections

110

a-b

by an O-ring

115

a-b

. Each jet insert is further secured within the pipe sections

110

a-b

by a snap ring

116

a-b

which corresponds with grooves

117

a-b

in the pipe sections

110

a-b

, as well as a jet insert key slot

118

a-b

which corresponds with a key (not shown) positioned within the pipe sections

110

a-b

, as shown in

FIGS. 5

a-d

. The key and key slot

118

a-b

configuration allows the four jet insert bores

114

a-d

of each jet insert

12

a-b

to be positioned in direct opposition to the jet insert bores

114

a-d

of the opposing jet insert

112

a-b

, such that each bore

114

on one jet insert

112

a

is in alignment with a bore

114

on the second jet insert

112

b

. The pipe sections

110

a-b

are thus configured to direct the fluid jetted from the jet inserts

112

a-d

, such that, upon discharge from the pipe sections

110

a-b

, the two jetted fluid flows will interact, causing fluid turbulence. In this example embodiment, the two jetted fluid flows are substantially in line for direct opposition, although other angles of interaction are present in alternate embodiments (not shown), including anticipated angled interactions, in accordance with our invention, as will occur to those of skill in the art upon review of the present disclosure. The jet inserts

112

a-b

may be dislodged from the pipe sections

110

a-b

by opening the removal tool ports

121

a-b

, and inserting a rod (not shown) into the pipe sections

110

a-b

until it reaches the jet insert

112

a-b

position.

In alternate embodiments (not shown), no jetting mechanism is provided, in which case the shearing function is provided only by the interaction of opposing fluid flows from pipe sections

110

a-b

. Furthermore, different combinations of jet inserts

112

a-b

, with differing numbers of bores

114

, as well as different types of jetting mechanisms and other high velocity shearing mechanisms, are contemplated in alternate embodiments (not shown), in accordance with our invention, as will occur to those of skill in the art upon review of the present disclosure.
