CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is being filed on 13 March 2017, as a PCT International patent application, and claims priority to U.S. Provisional Patent Application Serial No. 62/308,074, filed March 14, 2016, the disclosure of which is hereby incorporated by reference.

BACKGROUND

[0002] The present disclosure involves methods, devices, and systems for hydrating polymers. Conventional flow-through tank techniques for hydrating polymers involve mixing a polymer and liquid by directing the water-wetted dry polymer and liquid in a horizontal direction. Such a design, however, can create a slipstream within the vessels used to hydrate the polymers. This causes some polymers to flow through the tank quicker than intended, which results in polymers that are not hydrated as desired.

[0003] It is with respect to these and other considerations that the technology is disclosed. Also, although relatively specific problems have been discussed, it should be understood that the embodiments presented should not be limited to solving the specific problems identified in the introduction.

DETAILED DESCRIPTION

[0052] The present disclosure involves methods, devices, and systems for hydrating polymers. FIG. 1 shows a system 100 including a hopper 102 A and a pump 104 positioned next to a tank assembly 106 having a series of chambers 106A-106E. FIG. 2 shows a partial exploded view of some of the chambers 106A- B, and FIG. 3 shows a partial section view of some of the chambers 106A-B. During operation of the system 100, dry polymer is fed to the hopper 102A and processed (e.g., wetted and sliced) by a polymer wetting device 102B before entering the tank assembly 106. Wetted polymer is mixed with liquid in the tank assembly's series of chambers 106A-E, further wetting the polymer particles, to hydrate the polymer.

[0053] The tank assembly 106 includes a plurality of mixing chambers with five 106A-106E being shown in FIG. 1. FIG. 2 shows mixing chambers having an open interior bounded by a plurality of walls forming a generally rectangular configuration. The walls are coupled together with rounded corners. More particularly, the mixing chambers are shown having rectangular front wall 110 and back wall 112, that are positioned parallel to each other. The mixing chamber also includes a first side walls 114 and a second side wall 116 oriented substantially perpendicularly to the front wall 110 and the back wall 112. In aspects of the technology, the walls are coupled together by curved corner walls 118 extending between edges of the walls. A lower wall 120 (e.g., floor, base) is coupled to and oriented substantially perpendicularly to a lower end of each of the front wall 110, the back wall 112, the first side wall 114, and the second side wall 116. In embodiments, each mixing chamber includes and independent lower wall 120, while in other embodiments, the lower wall 120 may be one piece, to which the walls of each mixing chamber are coupled.

[0054] The corner walls 118 may have any curvature suitable for providing flow within the liquid to mix the polymer with the liquid. In embodiments, the curvature of the corner walls 118 may be designed, using computational fluid dynamics, to optimize the mixing of a particular type of liquid and/or polymer that may be expected to be provided to the system. In embodiments, for example, squared corners (e.g., corners formed from perpendicularly intersecting walls) have been found to form stagnant regions during mixing, and a round chamber often may result in a uniform spinning motion of the liquid and polymer. Both of these situations may reduce the amount of mixing that occurs in the chamber. Accordingly, a curvature that more approximately results in a generally rectangular chamber with at least slightly rounded corners may provide a more suitable mixing environment.

[0055] The illustrative system 100 shown in FIGS. 1-3 is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the present disclosure. Neither should the illustrative system 100 be interpreted as having any dependency or requirement related to any single component or combination of components illustrated therein. Additionally, various components depicted in FIGS. 1-3 may be, in embodiments, integrated with various ones of the other components depicted therein (and/or components not illustrated), all of which are considered to be within the ambit of the present disclosure.

[0056] FIGS. 2 and 3 show the first mixing chamber 106A being operatively coupled to the second chamber 106B by an under-over baffle 122 having a fluid conduit positioned between a baffle inlet 124 and outlet 126. The baffle inlet 124 is defined by an opening in a lower portion of the back wall 112 of the first mixing chamber 106 A. The adjacent mixing chamber 106B includes the baffle outlet 126 defined by an opening in an upper portion of the front wall 110 of the second mixing chamber 106B. The openings can be rectangular or elliptical shaped, among other shapes, and can extend to, or near, the edges of the back or front walls. A size of the openings may differ from chamber to chamber. For example, a width of the opening and baffle may be larger for chambers positioned later in the series.

[0057] The fluid conduit 128 includes an open interior region enclosed by an outside surface of the back wall of the first mixing chamber, an outside surface of the front wall of the second mixing chamber, two parallel opposed side baffle walls 130, a lower baffle wall 132, and an upper baffle wall 134.

[0058] While an under-over baffle 122 having a baffle inlet 124 and baffle outlet 126 are shown for the first chamber 106 A, it will be appreciate that any chamber of a system 100 may have an under-over baffle system. For example, any of chamber 106B - 106E may have an under-over baffle system.

[0059] Additionally, FIG. 3 shows the first mixing chamber 106 A having a polymer inlet 136 through which wetted polymer (e.g., pre-wet polymers) enters the mixing chamber. In operation, mixing of wetted polymer and liquid may be facilitated by mixing devices 138, although not all chambers require a mixing device 138. Mixing devices 138 are configured to mix wetted polymer and a liquid to hydrate the polymer to create a final polymer solution. For example, mixing devices 138 may mix the polymer and liquid by rolling (e.g., circulating the mixture in vertical directions). Mixing devices 138 may also mix the polymer and liquid by stirring (e.g., circulating the mixture in horizontal directions). FIG. 3 shows a mixing device 138 coupled to a top section of the first mixing chamber 106 A and having an impellor.

[0060] After mixing in the first chamber 106A, the polymer solution is directed through the under-over baffle 122. For example, the solution flows through the opening 124 in the bottom of the back chamber wall through the fluid conduit 128 and into the second mixing chamber 106B via the opening 126 in the top of the front wall of the second mixing chamber 106B. According to embodiments, under- over baffles may mitigate creation of a slipstream throughout the tank assembly 106. Specifically, with the baffles, there may be no "easy" path for liquid or polymer to travel along in the tank assembly 106 such that polymer is under-hydrated when leaving the assembly 106.

[0061] In embodiments, any number of the mixing chambers 106 A-E may include a mixing device 138. In embodiments, for example, each mixing chamber 106 A-E may include a mixing device 138, while in other embodiments, only one of the chambers 106 A-E may include a mixing device 138. For example, the first chamber 106 A may include a mixing device 138 while only one other chamber in the tank assembly 106 may utilize a mixing device 138. For example, FIG. 3 shows a second mixing chamber 106B without a mixing device. In certain embodiments, the mixing device 138 in the first chamber 106 A may be configured to mix more aggressively than other mixing devices disposed within the tank assembly 106. For example, the polymer solution in the first chamber 106 A may be aggressively rolled while solution in later tanks may be stirred before exiting the chamber.

[0062] Level sensors may be used to determine a level of a polymer solution in one or more of the mixing chambers and may communicate with a system controller, which controls various system operations. For example, in response to a level sensor's reading, the controller may increase or decrease a rate at which wetted polymer is added to the first mixing chamber 106A.

[0063] Although five chambers 106 A-E are shown in the tank assembly 106, any number of chambers can be used. For example, the number of chambers may depend on a property associated with the polymer hydration process like a minimum or maximum desired polymer concentration or fluid pressure. Moreover, although the chambers are shown as being similarly sized, chamber size may differ within the tank assembly 106. Additionally, according to embodiments, the chambers 106 A-E and baffles 122 may be configured to optimize progressive flow versus viscosity, and may be adjustable to progressive viscosity changes, relevant to flow (time) to hydrate (uncoil) the molecular chain. For example, in embodiments, the lower opening 124 may have a different size than the upper opening 126.

Corresponding openings in adjacent tanks may have differing sizes. For example, the width of the baffle inlet may be «inventors, can you describe how we size the inlet and outlet?».

[0064] In embodiments, the openings may be adjustable, manually and/or automatically, e.g., by moving a sliding wall panel up or down to enlarge or contract the opening. Embodiments may include a controller for facilitating a feedback control system that may be configured to automatically adjust the height and/or width of any one or more of the openings.

[0065] FIG. 4 is a block diagram depicting an illustrative operating environment 400 in accordance with embodiments of the disclosure. The operating environment 400 may be, be associated with, include, or be included within a polymer hydration system such as, for example the system 100 depicted in FIG. 1. As illustrated, the operating environment 400 includes a controller 402 configured to control operations of a polymer wetting device 404 that wets polymer particles and feeds the wetted polymer to a first mixing chamber (e.g., the first mixing chamber 106 A depicted in FIGS. 1-3. The polymer wetting device 404 may receive a measured amount (e.g., a measured volume or weight) of dry polymer from any type of dry material feeding mechanism such as, for example, an auger feeder. The polymer wetting device 404 proportionally controls addition of water, thereby wetting the polymer particles.

[0066] In embodiments, the controller 402 is configured to cause the polymer wetting device 404 to activate and/or deactivate and/or control a rate at which the polymer wetting device provides the wetted polymer to the first mixing chamber. For example, in embodiments, the controller 402 may cause the polymer wetting device 404 to provide the wetted polymer to the first mixing chamber at a first rate, determine that a condition is satisfied; and, in response to determining that the condition is satisfied, provide the wetted polymer to the first mixing chamber at a second rate. That is, the percentage, by weight, of polymer to water may be changed in a stepwise fashion from an initial percentage to a second percentage. The change in the percentage, by weight, may be due to a condition such as an amount of time that has passed, a certain water quality (measure in water clarity), a viscosity of the polymer solution in one or more of the mixing chambers, an output rate of the down stream made-down polymer (e.g., the flowrate of polymer-water mixture exiting a final (or intermediate) chamber,a level of the polymer solution in the first mixing chamber and/or a level of the polymer solution in an additional mixing chamber, and/or the like. In additional/alternative embodiments, the condition may be a high or low threshold, a range, a time period, and/or the like. The condition may be predetermined, dynamic, user-configurable, and/or the like.

[0067] In implementations, for example, the first rate may be greater than the second rate. In an aspects of the technology, the first and/or second rate may be no less than about 0.01wt% and no greater than about 2.0wt%, the first and/or second rate may be no less than about 1.0wt% and no greater than about 2.0wt, the first and/or second rate may be between 1.4wt% and 1.9wt% (e.g., about 1.5wt%, about 1.6%wt, about 1.7%wt, etc.). The operating environment 400 may include one or more level sensors 408, each disposed in a mixing chamber and configured to determine a level of polymer solution in the mixing chamber. The controller 402 may also be configured to control one or more mixing devices 406 disposed within the one or more mixing chambers. For example, in embodiments, a first mixing device may be disposed in a first mixing chamber, a second device may be disposed in a second mixing chamber, and/or the like. The controller 402 may be configured to activate/deactivate the one or more mixing devices, control a rate at which each mixing device operates, and/or the like. For example, in embodiments, the controller 402 may be configured to cause a first mixing device to mix a volume of polymer solution more aggressively than at least one additional mixing device (e.g., a mixing device in a second mixing chamber), avoiding shear or damage to the polymer solution as it progressively hydrates. The first mixing device may be configured to mix the volume of polymer solution by rolling the volume of polymer solution within the first mixing chamber, while an additional mixing device may be configured to mix the volume of polymer solution by stirring the volume of polymer solution within an additional mixing chamber.

[0068] The controller 402 may be configured to dynamically control the one or more mixing devices 406 in response to any number of determinations that the controller 402 may be configured to make, based on one or more conditions of the system. Although not illustrated, the operating environment 400 may include any number of different types of sensors configured to determine any number of different conditions of the system such as, for example, temperature, fluid pressure, viscosity, flow rates, polymer concentrations, and/or the like. The sensors may include, for example, thermometers, samplers, optical sensors, transducers, and/or the like. [0069] The controller 402 may also be configured to control one or more baffle adjustors 410. A baffle adjustor 410 may be associated with one or more baffles and may be configured to adjust one or more dimensions of one or more baffle inlets.

[0070] Turning briefly to FIG. 7, an illustrative baffle adjustor 702 configured to adjust a baffle 702 is depicted, in accordance with embodiments of the disclosure. As shown in FIG. 7, the baffle may include an open interior region 706 partially enclosed by two parallel opposed side baffle walls 708 and 710, an upper baffle wall 712, and a lower baffle wall 714. A baffle inlet 716 is defined in a lower portion of the side baffle wall 708 (which also may form a back wall of a first mixing chamber), and a baffle outlet 718 is defined in an upper portion of the side baffle wall 710 (which also may form a front wall of a second mixing chamber).

[0071] The baffle adjustor 702 may include an actuator 720 configured to move a first arm 722 that is coupled to a first baffle door 724 to adjust the size of the baffle inlet 716, and a second arm 726 that is coupled to a second baffle door 728 to adjust the size of the baffle outlet 718. In embodiments, each baffle door 724 and 728 may be coupled to a different actuator 720. According to embodiments, any number of different types of mechanisms may be used to adjust the sizes of the baffle inlet 716 and outlet 718. In embodiments, the controller 402 depicted in FIG. 4 may be communicatively coupled to the actuator 720 to facilitate control thereof.

[0072] Returning to FIG. 4, the controller 402 may be operatively (e.g., communicatively) coupled to any number of various components of the operating environment 400. These connections (and any other connection contemplated between two or more components) may be wired, wireless, or a combination of these. The controller 402 may be, include, or be included in one or more processors, programmable logic controllers (PLCs), proportional-integral-derivative (PID) controllers, electronic circuits, and/or the like, and may be implemented in a computing device (e.g., a laptop, a mobile device, a server, a control panel 412, and/or the like), integrated with the polymer feeder 404, and/or the like. The controller 402 may be implemented using hardware, software, firmware, and/or a combination of these. In embodiments, the controller 402 may be configured to dynamically adjust the polymer feed rate, mixing speed, and/or baffle size, in response to any number of different conditions, optimizations, feedback control loops, and/or the like. It will be appreciated by individuals having skill in the relevant arts that the controller 402 may be configured to implement pre-set capabilities, user-configurable inputs and outputs, bidirectional communications, security paradigms, event logging, transactions, automatic controls, programmable controls, and/or the like.

[0073] The controller 402 may be configured to receive, and act in accordance with, input from a user and/or other device (e.g., via the control panel 412). The control panel 412 may be, be similar to, include, or be included in any control panel, controlling computing device, control station, and/or the like, associated with one or polymer hydration (e.g., make-down) systems, as described herein. In embodiments, the control panel 412 may include any number of different types of input devices and/or output devices. The controller 402 may be disposed in, integrated with, and/or coupled to (e.g., physically and/or communicatively) the control panel 412. The control panel 412 may include panel indicator lights, security components, manual controls, and/or the like, that enable a user to obtain information and/or control any number of various aspects of the illustrative operating environment 400.

[0074] The illustrative operating environment 400 shown in FIG. 4 is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the present disclosure.

[0081] As described above, embodiments of the subject matter disclosed herein include systems of mixing chambers for hydrating polymers. FIG. 6 is a flow diagram depicting an illustrative method 600 of hydrating a dry polymer using a number of mixing chambers, in accordance with embodiments of the disclosure. In embodiments, adjacent mixing chambers may be operatively coupled by an under- over baffle, and each mixing chamber may include an open interior bounded by a number of walls having a generally rectangular configuration, where adjacent walls are coupled by rounded corners. In embodiments, the system may include at least two mixing chambers such as, for example, two mixing chambers, three mixing chambers, four mixing chambers, five mixing chambers, and/or the like. Embodiments of the method 600 may include determining a number of mixing chambers to include in the system based on a property associated with the polymer hydration process. The property may include, for example, at least one of a minimum desired polymer concentration and a maximum desired polymer concentration, a fluid pressure, and/or the like.

[0082] Embodiments of the method 600 include providing a volume of fluid to a first mixing chamber (block 602) and providing a wetted polymer solution to the first mixing chamber to create a volume of polymer solution (block 604). In embodiments, providing the wetted polymer to the first mixing chamber may include providing the wetted polymer to the first mixing chamber at a first rate, determining that a condition is satisfied, and, in response to determining that the condition is satisfied, providing the wetted polymer to the first mixing chamber at a second rate. In embodiments, the first rate may be greater than the second rate; and the second rate may be no less than about 0.01wt% and no greater than about 2.0wt%. In embodiments, the second rate may be no less than about 1.0wt% and no greater than about 2.0wt%. In embodiments, the second rate may be, for example, between 1.4wt% and 1.9wt% (e.g., about 1.5wt%). The condition may include, for example, at least one of an amount of time and a level of the polymer solution in the first mixing chamber.

[0083] As shown in FIG. 6, the method 600 may further include rolling, using a first mixing device disposed in the first mixing chamber, the volume of polymer solution (block 606). The volume of polymer solution is moved from the first mixing chamber into a baffle via a baffle inlet (block 608), through the baffle and into a second mixing chamber via a baffle outlet (block 610). Embodiments of the method 600 further include stirring, using a second mixing device disposed in the second mixing chamber, the volume of polymer solution (block 612).
