DETAILED DESCRIPTION
(19) In the following, reference is made to embodiments of the disclosure. It should be understood; however, that the disclosure is not limited to specific described embodiments. Instead, any combination of the following features and elements, whether related to different embodiments or not, is contemplated to implement and practice the disclosure. Furthermore, although embodiments of the disclosure may achieve advantages over other possible solutions and/or over the prior art, whether or not a particular advantage is achieved by a given embodiment is not limiting of the disclosure. Thus, the following aspects, features, embodiments and advantages, are merely illustrative and are not considered elements or limitations of the claims except where explicitly recited in a claim. Likewise, reference to the disclosure shall not be construed as a generalization of inventive subject matter disclosed herein and should not be considered to be an element or limitation of the claims except where explicitly recited in a claim.
(20) Although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, components, region, layer or section from another region, layer or section. Terms such as first, second and other numerical terms, when used herein, do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed herein could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments.
(21) When an element or layer is referred to as being on, engaged to, connected to, or coupled to another element or layer, it may be directly on, engaged, connected, coupled to the other element or layer, or interleaving elements or layers may be present. In contrast, when an element is referred to as being directly on, directly engaged to, directly connected to, or directly coupled to another element or layer, there may be no interleaving elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion. As used herein, the term and/or includes any and all combinations of one or more of the associated listed terms.
(22) Some embodiments will now be described with reference to the figures. Like elements in the various figures will be referenced with like numbers for consistency. In the following description, numerous details are set forth to provide an understanding of various embodiments and/or features. It will be understood; however, by those skilled in the art, that some embodiments may be practiced without many of these details, and that numerous variations or modifications from the described embodiments are possible. As used herein, the terms above and below, up and down, upper and lower, upwardly and downwardly, and other like terms indicating relative positions above or below a given point are used in this description to more clearly describe certain embodiments.
(23) Aspects of the disclosure introduce a method and design of RPB which increase efficiency by keeping the component flow rates the same but reducing the size and footprint. Referring to
(24) In one example embodiment, compactness is a complementary advantage as well as a rotational speed that can be decreased to maintain the same mass transfer coefficient. This, in turn, leads to higher reliability of the design and less energy consumption required for rotation due to less friction in the bearings. A coaxial shaft which allows for rotation is presented in
(25) The liquid 113, fed into the axial shaft 103, flows from the top and is injected through the nozzles 114 onto the surfaces of the discs 101, 102. The nozzles 114 have two injectors, one part of them is directed radially 115 to supply internal discs, while others 116 are tangential with the same direction of external discs 101 rotation. Thus, all the discs 101, 102 surfaces are being covered by thin liquid films 117 flowing radially outward due to centripetal acceleration. After, the liquid leaves the discs 101, 102 rims as a thin sheet of droplets.
(26) These droplets form a film on the casing 118 wall, which flows down to the bottom of the casing 118 to the exit 119. The gas outlet 110 may be defined by a lip placed around the overall casing, defining an opening 120.
(27) The gas 108, supplied into the casing 118, flows through annular channels 109, formed between discs and the liquid films 117 flowing over rotating discs 101, 102 to the gas clearances 111 and slots 112 in the discs 101, 102 and further to the exit 110, located at the top of the casing 118. The gas 108 acquires tangential velocity in the annular channels due to torsional stress induced by the rotation of the discs 101, 102. The sum of the radial velocity (due to radial flow) and tangential velocity (due to torsional stress) leads to a converging spiral flow inside channels. As will be understood, a plurality of openings may be provided into the casing 118 for injection of gas. Such openings may have different shapes, such as round, oval, triangular, a simple perforation or other more complex geometries.
(28) In one example embodiment, a motor supplies shafts with the rotation torque through a gearbox. The whole assembly is housed in the casing 118. The contact of the phases for separation or reaction takes place in the annular channels and, to a minor extent, on the casing 118.
(29) In some operational regimes for a non-viscous fluid and high speed of the discs rotation, a nozzle can be situated on individual rotational rings. In this example embodiment, fluid splash is avoided. Examples of alternative embodiments are presented in

(33) The counterrotation discs method can be applied to other RPBs' types as well. Another embodiment based on the methods described and applied to the split packing RPBs is presented in

(35) The liquid 613, fed into the axial shaft 603, flows from the top and is injected through the nozzles onto the surfaces of the discs 601, 602. Thus, all the discs 601, 602 packings 621 are being covered by thin liquid films flowing radially outward due to centripetal acceleration.
(36) These droplets form a film on the casing 618 wall, which flows down to the bottom of the casing 618 to the exit 619. The gas outlet 610 may be defined by a lip placed around the overall casing, defining an opening 620.

(46) Embodiments of the apparatus and methods above can be performed in conjunction with digital apparatus. Such digital controlled apparatus may include computing apparatus, such as computers, laptops, servers and cloud computing-based units. These digitally controlled apparatus may be programmed with non-volatile computer instructions to allow the digital control of equipment within the field. Such control may, in some alternatives, use artificial intelligence networks or systems. In some further embodiments, the artificial intelligence networks may have feedback loops to allow the network to be trained to become more efficient over time. Operations; therefore, may be optimized according to past events, thereby saving costs. Control units on the RPBs may have their own computing apparatus that link to network servers, for example, to allow for remote operation of the RPB. Input parameters, such as fluid flow, temperature control (in and out) may also be controlled through the use of solenoid valves that have actuators that are controlled either locally, through artificial intelligence and/or from a remote workstation. Records may be kept by the computing apparatus and the optimum processing may be achieved by periodic re-learning of the system based on previous performance instead of a training set provided by programmers. Embodiments using artificial intelligence may use a single node layer that is updated periodically. Other embodiments using artificial intelligence may use multiple layer technology to provide a deeper learning capability.
