  • the method includes supplying an impinging solvent fluid through a nozzle extending from a first end of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture by entraining gas within the liquid mixture.
  • the method includes supplying solvent through an inlet on a second side of the mixing vessel which is tangential to a wall of the mixing vessel to introduce swirl to fluid in the mixing vessel.
  • generating the roiling surface includes projecting the impinging solvent fluid out of the nozzle through the gas pocket and entraining gas from the gas pocket into the liquid mixture to a depth equal to or greater than one-half a radius of the mixing vessel.
  • Entraining gas within the liquid mixture can include entraining a gas volume ranging from 2 to 20 times a liquid volume of the impinging solvent fluid.
  • FIG. 1 an illustrative view of an embodiment of a discharge system in accordance with the disclosure is shown in Fig. 1 and is designated generally by reference character 100.
  • Figures 2-4 Other embodiments and/or aspects of this disclosure are shown in Figures 2-4 .
  • the systems and methods described herein can be used to mix one or more soluble gas or gas and liquid feedstocks with a solvent, for example, saltwater, and discharge the solution with a known gas solubility saturation level such that the saturation level of gas in the liquid is well below that of typical bubble formation when released. This minimizes potential bubble formation from turbulent conditions or thermal hotspots after release.
  • a discharge system 100 includes a mixing vessel 102 and a feedstock input 104 defining a feedstock flow path 108 in fluid communication with mixing vessel 102. It is contemplated that the feedstock through feedstock flow path 108 can be in the form of a gas or gas-fluid mixture and feedstock input 104 can draw from multiple feedstock sources.
  • a longitudinal axis A is defined between first and second sides 117 and 119, respectively.
  • a solvent input 106 is in fluid communication with mixing vessel 102. Feedstock dissolves within the solvent thereby generating an effluent discharge solution having a known gas solubility saturation.
  • a discharge output 110 is in fluid communication with an outlet 112 of the mixing vessel 102 to discharge the effluent.
  • solvent input 106 includes two lines.
  • a first 107 of the two lines defines a flow path to mixing vessel 102 through a nozzle 118 and a second 107' of the two lines defines a flow path to mixing vessel 102 through an inlet 128 proximate to a second side 119 of mixing vessel 102, e.g. on a lower part 123 of mixing vessel 102 entering through a sidewall 121.
  • Nozzle 118 extends from first side 117 of the mixing vessel 102 into a cavity 120 defined by mixing vessel 102.
  • Solvent input 106 is in fluid communication with nozzle 118 to direct a solvent toward a gas pocket, indicated schematically with arcuate lines grouped together, generated by gas entering with the feedstock through feedstock input 104.
  • Nozzle 118 provides a high velocity jet of solvent into feedstock gas and in bubbles being driven deep into the mixer fluid. It is contemplated that placement of nozzle 118 on first side 117, e.g.
  • mixing vessel 102 aids control of gas feed over the entire operating envelope, provides consistent uptake under pitch and roll as well as level cruise conditions, allows control of an interface 113 between the gas pocket and the liquid mixture, sustains continuous high gas uptake rate through improved kinetics, is easier to service, and provides even flow distribution across the surface area of the mixing vessel 102 making efficient use of the volume of mixing vessel 102.
  • nozzle 118 can produce a highly kinetic cone shaped dispersion pattern of evenly distributed liquid droplet streams across the surface area at the interface between the gas pocket and the liquid mixture.
  • the spray pattern of nozzle 118 is substantially symmetric, as schematically indicated in Fig. 1 , to fully utilize the cross sectional area of mixing vessel 102. This, in turn, generates a substantially even roiling surface in order to maximize gas uptake from gas pocket into solvent present in the liquid mixture and that spraying from nozzle 118.
  • a roiling surface in accordance with some embodiments, can be defined as a highly turbulent liquid/gas flow such that the impinging liquid, in this case the solvent incoming from nozzle 118, entrains gas from the gas pocket into the liquid to a depth of not less than one-half a radius R of mixing vessel 102 and preferably two times radius R.
  • Nozzle 118 is positioned so that a tip 115 of nozzle 118 projects approximately 1.25-2.54 cm (0.5-1 inch) below the top of a cover 127 of mixing vessel 102 to improve initiation of a gas pocket and maintenance of the roiling surface during a given discharge of feedstock event.
  • lines 107 and 107' are downstream lines.
  • Solvent input 106 includes a single line 114 upstream from two lines 107 and 107' and includes a flow split orifice 116 between single line 114 and two lines 107 and 107'.
  • Inlet 128 on second side 119 of mixing vessel 102 is tangential to sidewall 121 of mixing vessel 102 to introduce swirl to fluid in the mixing vessel 102. With this substantially tangential entrance, flow swirl occurs in the bottom of mixing vessel 102, as oriented in Fig. 2 , providing both dilution of solvent flow from nozzle 118 and separation of possible bubbles within lower part 123 of mixing vessel 102.
  • Lower part 123 is defined between second side 119 of mixing vessel 102 and a bottom perforated plate 136b, described below. These bubbles then flow radially inward toward longitudinal axis A of mixing vessel 102 and may float up through perforated plates 136b and 136a toward first side 117 of mixing vessel 102.
  • a packing material 134 is above inlet 128, as originated in Fig. 1 , and reduces and/or eliminates the swirl from inlet 128, resulting in more even distribution as the bubbles rise to the top.
  • a sparger 130 is operatively connected to an end of feedstock flow path 108 that is part of feedstock input 104.
  • Sparger 130 extends from the end of the feedstock flow path 108 into cavity 120 to direct incoming feedstock evenly toward nozzle 118 and first side 117 of mixing vessel 102.
  • Sparger 130 generates gas bubbles within mixing vessel 102 when feedstock is being fed into mixing vessel 102.
  • sparger 130 is cross-shaped with holes 131 oriented upward toward first side 117 to create an even distribution of gas bubbles across mixing vessel 102 to counter downward flow, e.g. toward second side 119, of liquid solvent from nozzle 118. It is contemplated that a variety of sparger configurations and shapes can be used, for example, a spiral shape, an "X" shape, or any other suitable shape that provides even distribution over the span from front to back and side to side within mixing vessel 102.
  • Sparger 130 is placed near the bottom of mixing vessel 102, but within the zone of packing material 134, described below, so that additional uptake occurs in packing material 134, and small bubbles are swept from packing material 134 surface rather than allowed to accumulate and cause an increase in downward flow velocity of the solvent from nozzle 118.
  • Sparger 130 includes holes 131 facing first side 117 of mixing vessel 102. Size and number of holes 131 is selected to maximize gas uptake at both low and high pressure conditions, and eliminate the potential for bubbles getting sucked into the effluent outlet stream.
  • holes 131 can be approximately 0.1 cm (0.040 inches) in diameter and spaced evenly along a pair of tubes that make up the cross shape. The bubbles generated need to be bubbles small enough to not impede liquid flow, yet the hole size and number of holes needs to be sufficient to keep injection pressure drop across sparger 130 within acceptable parameters.
  • the number of holes 131 and size of holes 131 can be selected such that about 0.07 bar (1 psi) of delta pressure is generated at the maximum volumetric flow of gas, and less than 0.14 bar (2 psi) of pressure is generated at the maximum flow of liquid-gas, for the desired feedstocks.
  • Higher pressure drops tend to create either larger bubbles, which can result in a flow field impeding downward solvent flow, or high velocity jets of liquid which may also disturb the downward flow field. It is important to keep the downward flow field slow and even to allow small bubbles to ascend into the gas pocket at the top of mixing vessel 102. These bubbles may evolve in the solvent or feedstock, or cleave from larger bubbles at the exit of sparger 130.
  • discharge output 110 includes a flow restrictor 132 downstream from outlet 112 of mixing vessel 102.
  • the solvent liquid entering either nozzle 118 or inlet 128 can include other dissolved gases, e.g. atmospheric gases.
  • the partial pressure of these other contaminate gasses over the solvent liquid is initially zero.
  • additional gas such as that found in the feedstock
  • Atmospheric gases such as nitrogen and oxygen, have low solubility kinetics, and once allowed to come out of the solvent, are slow to dissolve. Further, they tend to form very small bubbles of low buoyancy that tend to be easily entrained in the discharge flow through discharge output 110 instead of being re-dissolved in the solvent and then discharged through outlet 112.
  • flow restrictor 132 increases the pressure of the solution in mixing vessel 102.
  • the resulting increase in pressure in mixing vessel 102 reduces the potential for atmospheric gases, such as nitrogen and/or oxygen, or other solvent gas contaminants from coming out of the solvent in mixing vessel 102.
  • a minimum pressure at discharge is less than four times a solvent surface pressure at ambient temperature.
  • Flow restrictor 132 is sized to generate a delta pressure equal to four times the solvent surface pressure at ambient temperature minus the minimum pressure at outlet 112. For example, if ocean water is the solvent and the ocean surface pressure is 1 bar (15 psia) at ambient surface conditions, the minimum discharge pressure from the vehicle is less than 4.1 bar (60 psia)
  • mixing vessel 102 includes packing material 134 in cavity 120 for even flow of fluid throughout mixing vessel 102.
  • Mixing vessel 102 includes perforated plates 136, an upper perforated plate 136a and a bottom perforated plate 136b, opposite from one another across packing material 134.
  • Packing material 134 is defined between solvent input 106 and discharge output 110.
  • Packing material 134 begins at a distance Di from tip 115 of nozzle 118 measured along longitudinal axis A of the mixing vessel 102. Di is equal to one and one-half times radius R of the mixing vessel 102.
  • Packing material 134 extends through mixing vessel 102 along longitudinal axis A the mixing vessel 102 a distance D 2 .
  • D 2 is at least six times radius R of mixing vessel 102.
  • packing material 134 can have an effective void volume of greater than 90%.
  • Sparger 130 is located above the bottom of packing material 134, and a mixing zone, e.g. lower part 123, where solute diluent is added free of packing material, is located below packing material 134 prior to outlet 112.
  • a mixing zone e.g. lower part 123, where solute diluent is added free of packing material, is located below packing material 134 prior to outlet 112.
  • the average void space created by packing material 134 can be greater than the maximum sparger bubbles generated when feedstock gas is added, allowing the bubbles to percolate up through packing material 134 and squeeze through upper perforated plate 136a into the turbulent mixing zone, e.g. area between nozzle 118 and upper perforated plate 136a.
  • Packing material 134 acts as a buffer a zone between outlet 112 and nozzle tip 115 to reduce or eliminate turbulence from turbulent mixing zone and balance flow across the cross sectional area of mixing vessel 102. Further, cross flow patterns are reduced, regions for bubbles to become trapped before they can flow deeper are created, and the flow velocity after mixing allows more thorough distribution of saturated solute, preventing pockets or slugs of overly saturated effluent from being discharged.
  • perforated plates 136a and 136b are used at the top and bottom of the zone of packing material 134 to properly position packing material 134.
  • Each plate 136a and 136b has holes 137 equaling about 25% of the total cross sectional area, allowing low velocity relative to the nozzle turbulence, but sufficient to create pressure drop above upper perforated plate 136a resulting in fairly even flow distribution through packing material 134.
  • the diameter of holes 137 is sized such that the solvent flow velocity in the downward direction is less than the bubble rise rate from sparger 130 so that gas entering mixing vessel 102 from sparger 130 is prevented or resisted from being entrained through bottom perforated plate 136b.
  • holes 137 of plates 136a and 136b are greater than the size of sparger holes 131 by more than 30%, since some pressure drop is generated in sparger 130 when feedstock gas flows, and the resulting bubbles expand as they enter cavity 120 of mixing vessel 102.
  • mixing vessel 102 has a larger diameter at a lower end, e.g. proximate to inlet 128, than at first side 117.
  • a method 200 for generating turbulence on a liquid surface within a mixing vessel includes supplying the mixing vessel with feedstock fluid through a feedstock input, e.g. feedstock input 104, and solvent fluid, e.g. a diluent, through an inlet, e.g. inlet 128, to generate a liquid mixture and a gas pocket in the mixing vessel, as shown by box 202.
  • Method 200 includes supplying an impinging solvent fluid through a high dispersal nozzle, e.g. nozzle 118, extending from a first end, e.g.
  • first side 117, of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture, as shown by box 204.
  • Generating the roiling surface includes projecting the impinging solvent out of the nozzle through the gas pocket and entraining gas from the gas pocket into the liquid mixture to a depth equal to or greater than one-half a radius, e.g. radius R, of the mixing vessel, as shown by box 206.
  • Entraining gas from the gas pocket into the liquid mixture includes entraining a gas volume ranging from two to twenty times a liquid volume of the impinging solvent fluid, as indicated by box 208.
  • the entrained gas volume can be less or more than two to twenty times the volume of the impinging solvent fluid, and can vary over a wide pressure and temperature range, and a wide range of gases or solvents.
  • liquid stream velocities from the nozzle greater 15.24 m/s (50 ft/sec) can have a greater delta pressure to achieve a roiling surface for a variety of gas-fluid and/or gas mixtures.
  • Embodiments of the invention provide a high surface area ratio and mechanical agitation through the nozzle to improve both soluble gas saturation and high uptake kinetics.
  • Gas uptake is achieved by feeding the liquid solvent through the nozzle while managing the liquid level in mixing vessel 102 at an optimal gas uptake point.
  • the methods and systems of the present disclosure as described above and shown in the drawings, provide for discharge systems having superior properties including the ability to maximize uptake rate for a gas into a liquid solvent to form an effluent discharge solution, while still reducing and/or preventing bubbles in the effluent discharge.
