Description

[0001] Technical field of the present disclosure

[0002] The present disclosure generally relates to pipeline contactors for facilitating chemical reactions and / or chemical extractions between immiscible liquids.

[0003] BACKGROUND OF THE DISCLOSURE

[0004] One method of reacting immiscible liquids (e.g., aqueous and organic phases) includes creating a dispersion of one phase in another phase to produce droplets with a large surface area where mass transfer and reaction can occur. After mixing the reactants, phase separation is required for product purity and quality. However, when using a dispersion method, phase separation can be difficult and time consuming.

[0005] Alternative approaches using fiber reactors or pipe contactors have been employed, wherein fibers or membranes disposed within a pipe provide increased surface area to promote reactions between immiscible liquids while avoiding agitation of the immiscible liquids and thereby forming difficult to separate dispersions / emulsions. Examples of pipe contactors are described in U.S. Patents 7,618,544 and 8,128,825, both of which are incorporated herein in their entirety.

[0006] However, pipeline contactors are generally expensive to construct and maintain, with much of this cost associated with the fibers or membranes used to create increased surface area for mass transfer or reaction. Thus, there remains a need for an efficient and cost-effective pipeline contactor.

[0007] Brief description of the present disclosure

[0008] According to an embodiment of the present disclosure, a pipeline contactor with improved efficiency and reduced production cost is provided. Conventionally, it is believed that maximizing the surface area of ​​the fiber material in the pipeline contactor can achieve a more complete reaction between immiscible liquids. However, the inventors surprisingly found that by reducing the amount of fiber material in the pipeline contactor to a certain extent, the pipeline contactor can more effectively promote chemical extraction and / or chemical reaction between immiscible liquids introduced into the pipeline contactor.

[0009] Utilization of this discovery provides tremendous benefits in terms of the cost of building and maintaining such a pipeline contactor, since the fiber material used therein can account for more than half of the total construction cost. In addition, the reduction of fiber material within the pipeline contactor allows for greater throughput or flow of reactant liquids. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following figure illustrates an embodiment of the subject matter disclosed herein. The claimed subject matter may be understood by reference to the following description in conjunction with the accompanying drawings, wherein:

[0012] FIG. 1 illustrates an example of a pipeline contactor that may be used in the methods described herein.

[0013] Detailed Description

[0014] The following disclosure provides many different embodiments or examples. Specific examples of components and arrangements are described below to simplify the disclosure. Of course, these are merely examples and are not intended to be limiting. In addition, the disclosure may repeat reference numbers and / or letters in various examples. This repetition is for the purpose of simplification and clarity, and does not itself specify the relationship between the various embodiments and / or configurations discussed.

[0015] Referring to Figure 1, a pipeline contactor may include a pipeline 10 having a bundle of elongated fibers 12 within the pipeline 10 for a portion of its length. The fibers 12 are secured to a tube 14 at a node 15. The tube 14 extends beyond one end of the pipeline 10 and is operably associated with a metering pump 18 that pumps a first (confined) phase liquid through the tube 14 and onto the fibers 12. An inlet tube 20 is operably connected to the pipeline 10 upstream of the node 15, the inlet tube 20 being operably associated with a metering pump 22. The pump 22 supplies a second (continuous) phase liquid through the inlet tube 20 and into the pipeline 10, wherein the second phase liquid is squeezed between the confined coated fibers 12. At the downstream end of the pipeline 10 is a gravity separator or settling tank 24 into which the downstream ends of the fibers 12 may extend. Operably associated with the upper portion of the gravity separator 24 is an outlet line 26 for outlet of one liquid, and operably associated with the lower portion of the gravity separator 24 is an outlet line 28 for outlet of the other liquid, wherein the level of the interface 30 existing between the two liquids is controlled by a valve 32, which is operably associated with the outlet line 28 and is adapted to act in response to a level controller generally indicated by the numeral 34.

[0016] Although the pipeline contactor shown in FIG. 1 is arranged so that the fluid flow traverses in a horizontal manner, the arrangement of the pipeline contactor is not limited thereto. In some cases, the pipeline contactor can be arranged so that the inlet pipes 14 and 20 and the node 15 occupy the upper part of the device and the settling tank 24 occupies the bottom of the device. For example, the pipeline contactor shown in FIG. 1 can be rotated about 90° parallel to the plane of the paper to arrange the inlet pipes 14 and 20, the node 15 and the settling tank 24 in the upper and lower positions described. Such an arrangement can use gravity to help push the fluid through the contactor. In some other embodiments, the pipeline contactor depicted in FIG. 1 can be rotated about 90° in the opposite direction parallel to the plane of the paper so that the inlet pipes 14 and 20 and the node 15 occupy the bottom of the device, and the settling tank 24 occupies the upper part of the device. In such a case, the hydrophilicity, surface tension and repulsive force of the continuous phase fluid will keep the restricted phase fluid confined to the fiber, regardless of whether the fluid flows upward, downward or laterally, and therefore sufficient contact can be obtained to affect the desired reaction and / or extraction without opposing gravity. It should be noted that such an inverted arrangement of the pipe contactor is applicable to any extraction method described herein and any other type of fluid contact method that can be performed in a pipe contactor. It should also be noted that for any extraction method described herein or for any other method that can be performed in a pipe contactor, the pipe contactor can be arranged in an inclined position (i.e., the side walls of the pipe contactor can be arranged at any angle from 0° to 90° relative to the floor of the room in which the pipe contactor is arranged).

[0017] According to the method of the present disclosure, the first extractant or reactant liquid can be introduced and introduced onto the fiber 12 through the tube 14. The second liquid immiscible with the first liquid can be introduced into the pipeline 10 through the inlet tube 20 and through the space or void space between the fibers 12. The fiber 12 will be wetted by the first liquid in preference to the second liquid. The first liquid will form a film on the fiber 12, and the second liquid will flow therethrough. Due to the relative motion of the second liquid relative to the first liquid on the fiber 12, a new interface boundary is continuously formed between the second liquid and the first liquid, and therefore, fresh liquid contacts the extractant, thereby causing and accelerating extraction. Without being bound by theory, it is believed that the first liquid forms a film on the fiber 12, which is restricted to a greater extent than the second liquid, and this promotes the relative motion between the two liquids.

[0018] According to the method of the present disclosure, the first liquid is introduced into the pipeline 10 at a first rate and the second liquid is introduced at a second rate. The first and second rates can be the same or different from each other and can be constant or variable. In one or more embodiments, the ratio of the first rate to the second rate is 2:1 to 1:10, 1:1 to 5:1, 1:1 to 3:1, or 5:3 to 2:1.

[0019] According to an embodiment of the present disclosure, the fibers 12 are arranged in the pipe 10 so that the fibers 12 are arranged in a manner similar to that of the fibers 12 in cm. 2 / cm 3 The surface area density (SA density) is measured to be between 100 and 490. The SA density represents the total surface area of ​​the fibers 12 per cubic centimeter of volume within the conduit 10 at the location within the conduit 10 containing the fibers 12. As referred to herein, the surface area of ​​the fibers 12 is calculated based on the average fiber diameter without taking into account any surface features of the fibers 12 (e.g., pores within a porous fiber). As a non-limiting example, for fibers having substantially the same diameter and extending generally linearly from an inlet to an outlet of a conduit, such as conduit 10, the SA density can be determined by taking a middle portion of a predetermined length of the conduit (e.g., a length equal to 1 divided by the cross-sectional interior area of ​​the conduit such that the volume of the middle portion is equal to 1 cm 3 ), calculating the surface area of ​​a single fiber over the length and multiplying it by the total number of fibers in the conduit to obtain the total surface area of ​​the fibers, and then dividing the total surface area by the volume of the conduit over the length. As another example, the predetermined length can be set to the length of the fiber within the conduit (i.e., excluding the length of the fiber extending outside the conduit). This concept can be applied to fibers with different diameters in a straightforward manner, for example, by calculating the fiber surface area separately based on the number of fibers with each diameter.

[0020] According to some embodiments, the SA density can be at least 100, at least 105, at least 110, at least 115, at least 120, at least 125, at least 130, at least 135, at least 140, at least 145, at least 150, at least 155, at least 160, at least 165, at least 170, at least 175, at least 180, or at least 185, at least 190, at least 195, at least 200, at least 205, at least 210, at least 215, at least 220, at least 225, at least 230, at least 235, at least 240, or at least 245. According to some embodiments, the SA density may be at most 490, at most 485, at most 480, at most 475, at most 470, at most 465, at most 460, at most 455, at most 450, at most 445, at most 440, at most 435, at most 430, at most 425, at most 420, at most 415, at most 410, at most 405, at most 400, at most 395, at most 390, at most 385, at most 380, or at most 375. According to some embodiments, the SA density may be within a range between any of the foregoing lower and upper limits.

[0021] The fiber material used for the pipeline contactor and method described herein can be, but is not limited to, cotton, jute, silk, treated or untreated minerals, metals, metal alloys, treated and untreated carbon allotropes, polymers, polymer blends, polymer composites, nanoparticle-enhanced polymers, combinations thereof, and coated fibers thereof for corrosion resistance or chemical activity. Typically, the fiber type is selected to match the desired confined phase. For example, an organophilic fiber can be used with a substantially organic confined phase. For example, this arrangement can be used to extract organic materials from water, wherein the organic liquid is confined to the fiber. Suitable treated or untreated minerals include, but are not limited to, glass, alkali-resistant glass, E-CR glass, quartz, ceramics, basalt, combinations thereof, and coated fibers thereof for corrosion resistance or chemical activity. Suitable metals include, but are not limited to, iron, steel, stainless steel, nickel, copper, brass, lead, thallium, bismuth, indium, tin, zinc, cobalt, titanium, tungsten, nickel-chromium alloys, zirconium, chromium, vanadium, manganese, molybdenum, cadmium, tantalum, aluminum, anodized aluminum, magnesium, silver, gold, platinum, palladium, iridium, alloys thereof, and coated metals thereof.

[0022] Suitable polymers include, but are not limited to, hydrophilic polymers, polar polymers, hydrophilic copolymers, polar copolymers, hydrophobic polymers / copolymers, non-polar polymers / copolymers, and combinations thereof, such as polysaccharides, polypeptides, polyacrylic acid, polyhydroxybutyrate, polymethacrylic acid, functionalized polystyrene (including, but not limited to, sulfonated polystyrene and aminated polystyrene), nylon, polybenzimidazole, polyvinylidene nitrile, polyvinylidene chloride and polyvinylidene fluoride, polyphenylene sulfide, polyphenylene sulfone, polyether sulfone, polymelamine, polyvinyl chloride, polyvinyl acetate, polyvinyl alcohol, co-polyethylene-acrylic acid, acid), polyethylene terephthalate, ethylene-vinyl alcohol copolymer, polyethylene, polyvinyl chloride, polypropylene, polybutadiene, polystyrene, polyphenol-formaldehyde, polyurea-formaldehyde, polynovolac, polycarbonate, polynorbornene, polyvinyl fluoride, polychlorofluoroethylene, polyepoxy, polyethylene oxide, polyepoxy novolac vinylester, polyimide, polycyanurate, silicone, liquid crystal polymers, derivatives, composite materials, nanoparticle reinforcements, etc.

[0023] In some cases, the fiber can be wetted with a preferred phase to prevent corrosion by process streams, and / or the fiber can be coated with a functional polymer. For example, carbon fiber can be oxidized to improve wettability in aqueous streams, and polymer fibers can show improved wettability in aqueous streams and / or prevent corrosion by incorporating enough functional groups (including but not limited to hydroxyl, amino, acid, alkali, enzyme or ether functional groups) into polymers. In some cases, fiber can include chemical bonds (i.e., immobilization) thereon to provide such functional groups. In some embodiments, fiber can be an ion exchange resin, including those applicable to hydroxyl, amino, acid, alkali or ether functional groups. In other cases, glass and other fibers can be coated with acid, alkali or ionic liquid functional polymers. For example, carbon fiber or cotton fiber coated with acid-resistant polymers can be applicable to processing strong acid solutions. In some cases, fiber can include materials that have catalytic or extraction effects on ad hoc methods. In some cases, enzyme groups can be included in fiber to help specific reactions and / or extractions.

[0024] In some embodiments, all fibers in the pipeline contactor can be of the same material (i.e., having the same core material and, if applicable, the same coating). In other cases, the fibers in the pipeline contactor may contain different types of materials. For example, the pipeline contactor may include a group of polar fibers and a group of non-polar fibers. Other groups of different fiber materials can be considered. As described above, the fiber configuration (e.g., shape, size, number of filaments containing fibers, symmetry, asymmetry, etc.) in the pipeline contactor can be the same or different for the methods described herein. Such configuration variability can be a supplement or replacement for material changes between fibers. In some embodiments, different types of fibers (i.e., fibers of different configurations and / or materials) can be placed side by side in the contactor, with each group having its own respective inlet and / or outlet. In other cases, different types of fibers can extend between the same inlet and outlet. In any embodiment, different types of fibers can be dispersed separately in the pipeline contactor, or alternatively, each of the different types of fibers can be arranged together. In any case, the use of different types of fibers can facilitate multiple separations, extractions, and / or reactions simultaneously in the pipeline contactor by a single or even multiple continuous phase flows. For example, in the case where the pipe contactor is filled with a plurality of bundles of different fiber types, each bundle is connected to its own restricted phase fluid inlet and arranged obliquely, the bundles can be arranged so that the continuous phase fluid passes through the plurality of fiber bundles in sequence, with different materials being extracted by or from each bundle. The fiber diameter is not particularly limited and can be, for example, 5-150 μm, 10-100 μm, 12-75 μm, 15-60 μm, 17-50 μm, 20-45 μm, 20-35 μm or 20-25 μm. The length of the pipe contactor is not particularly limited and can be, for example, 0.25-10 m, 0.5-5 m, 0.75-3 m, 1-2.5 or 1.5-2 m. The diameter or width of the pipeline contactor is also not particularly limited, and can be, for example, 0.5 cm to 3 m, 5 cm to 2.5 m, 10 cm to 2 m, 15 cm to 1.5 m, 20 cm to 1 m, 25-75 cm, 30-70 cm, 35-65 cm, 40-60 cm, 45-55 cm or 50 cm.

[0025] Examples of chemical reactions that can be achieved using the pipeline contactors and methods of the present disclosure include, but are not limited to: epichlorohydrin reactions; O-alkylation (etherification); N-alkylation; C-alkylation; chiral alkylation; S-alkylation; esterification; transesterification; displacement (e.g., with cyanide, hydroxide, fluoride, thiocyanate, cyanate, iodide, sulfide, sulfite, azide, nitrite or nitrate); other nucleophilic aliphatic and aromatic substitutions; oxidation; hydrolysis; epoxidation and chiral epoxidation; Michael addition; aldol condensation; Wittig condensation; Darzens condensation; carbene reaction; thiophosphorylation; reduction; carbonylation; transition metal co-catalysis; HCl / HBr / HOCl / H2SO4 reaction; and polymer synthesis or polymer modification. In one or more embodiments, an organic halide (RX) and an organic acid (R'-H) can be coupled by the methods described herein to produce a coupled product (R-R'), wherein RX and R'-H can be on the same molecule or on different molecules. In such embodiments, the organic acid (R'H) can include a hydrocarbon acid such as cyclopentadiene, acetoacetate, or acetylene, or the organic acid can include a carboxylic acid; a thiocarboxylic acid; a phenol, an alcohol, a thiol, an amine, an ethanolamine, and the like. In other embodiments, water, alcohols, carboxylic acids, inorganic acids, thiols, amines, and the like can react with epoxides to form diols or substituted diols such as, but not limited to, alkyl ether alcohols, alkyl thioether alcohols, ester alcohols, and amino alcohols, phosphates, or borates.

[0026] In one or more embodiments, the pipeline contactor can be heated or maintained at a temperature of, for example, 15°C, 20°C, 25°C, 30°C, 35°C, 40°C, 45°C, 50°C, 55°C, 60°C, 65°C, 70°C, 75°C, 80°C, 85°C, 90°C, 95°C, 100°C, or a temperature range of greater than 100°C or any of the above values. In some embodiments, the pipeline contactor temperature is limited to the boiling point of the reactants. However, operating the pipeline contactor under pressure allows the use of reaction temperatures exceeding the boiling point of the reactants and allows the reaction temperature to exceed 100°C. The pressure within the pipeline contactor is not particularly limited and can be, for example, 5-75psi, 10-60psi, 15-40psi, 20-30psi, or 25psi.

[0027] According to the embodiments of the present disclosure, the cost of building and maintaining the pipeline contactor can be reduced by using less fiber material, while promoting more efficient chemical reactions and / or chemical extractions between immiscible liquids. In addition, due to the reduction of fiber material in the pipeline, the throughput or flow rate of the immiscible liquid can be increased, further improving the efficiency of the pipeline contactor.

[0028] Example :

[0029] The fiber was placed in a pipe to provide the SA density described in Table 1 below. A caustic solution (60 / 40 aqueous ethanol containing 2% NaOH) and an oil containing about 14% free fatty acids (FFA) were passed through the fiber at a rate of 75 ml / min and 125 ml / min, respectively. The oil phase and the caustic phase were then collected and separated. The extraction yields shown in Table 1 represent the percentage of FFA removed from the oil.
