[0026] Some embodiments of the present disclosure will be described herein by way of example with reference to the accompanying drawings. Now, with specific and detailed reference to the figures, it should be emphasized that the embodiments shown are by way of example and for the purpose of illustrative discussion of the embodiments of the present disclosure. In this regard, the description in conjunction with the figures enables those skilled in the art to clearly understand how to practice the embodiments of the present disclosure.

[0027] Figure 1 A fractionation system according to some embodiments is shown.

[0028] Figure 2 A flowchart of a method for fractionation according to some embodiments is shown. DETAILED DESCRIPTION

[0029] Fractionation is a technique for separating individual components or constituents that make up a mixture or composition. Fractionation utilizes the fact that each component of a composition or mixture (composed of several different components) has a unique boiling point or vaporization point that is different from the boiling points of the other components of the composition. Existing fractionation systems can be inefficient, unable to meet purity requirements, or both inefficient and unable to meet purity requirements. Embodiments of the present disclosure relate to improved fractionation systems that, in some embodiments, are efficient and capable of meeting the purification requirements for distilling liquid mixtures.

[0030] Figure 1 A fractionation system 100 according to some embodiments is shown. The fractionation system 100 includes a distillation vessel 102, a column 104, a mesh 106, a plurality of conduits 108 configured to fluidly connect to respective vacuum devices, and a fractionation head 110.

[0031] In some embodiments, the distillation vessel 102 is configured to receive a mixture, such as a liquid mixture. In some embodiments, the distillation vessel 102 can be, for example, a round-bottom flask, a conical flask, or a similar container capable of receiving a liquid mixture and being heated. In some embodiments, heat can be applied, for example, by a Bunsen burner or the like. It should be understood that this is an example, and the manner of applying heat to the distillation vessel 102 is not intended to be limiting.

[0032] According to some embodiments, the column 104 is fluidly connected to the distillation vessel 102 at a first end 112. According to some embodiments, the column 104 is fluidly connected to the fractionation head 110 at a second end 114. Between the first end 112 and the second end 114, the column 104 includes a mesh 106.

[0033] In some embodiments, the column 104 has a length L1. The length L1 can be selected based on, for example, the specific application of the liquid mixture being fractionated.

[0034] In some embodiments, the mesh 106 spans the length L2. In some embodiments, the length L2 is less than the length L1. In some embodiments, the length L2 can be selected based on, for example, a particular application of the liquid mixture being fractionated. In some embodiments, the length L2 can be selected based on the length L2.

[0035] In some embodiments, the mesh 106 is formed of a corrosion-resistant metal. In some embodiments, the corrosion-resistant metal comprises at least one of stainless steel, corrosion-resistant nickel alloys, or a combination thereof. It should be understood that these materials are examples. In some embodiments, non-metallic materials can be used for the mesh 106. For example, in some embodiments, the mesh can be made of glass, ceramic, a combination thereof, or the like.

[0036] In some embodiments, the mesh 106 can have a high surface area and a high porosity. Thus, in some embodiments, the high surface area and high porosity can provide a low pressure drop across the column. Thus, in some embodiments, the column length and separation efficiency can be increased without increasing the temperature to which the distillation vessel 102 is heated to cause distillation to occur.

[0037] In some embodiments, the mesh 106 can be formed from a plurality of flat material strips. In some embodiments, the flat material strips can be a corrosion-resistant metal or other materials, such as glass, ceramic, a combination thereof, or the like. In some embodiments, a configuration comprising flat material strips woven together can increase the surface area of the mesh 106 (i.e., increase the surface area to volume ratio) compared to the volume of the mesh 106. It should be understood that the geometries are examples, and other geometries, such as tubular or the like, can be used in accordance with the principles described in this specification.

[0038] The fractionation head 110 is fluidly connected to the second end 114 of the column 104. According to some embodiments, the fractionation head 110 includes a diverter 116. In some embodiments, the diverter 116 is a magnetically activated diverter. The magnetically activated diverter can reduce variability between distillations and provide better reproducibility based on the control of the magnetically activated diverter. The fractionation head 110 can include a timer to specify the position of the diverter 116. In some embodiments, the timer can be part of the diverter 116. In some embodiments, the timer can be configured to communicate electronically with the diverter 116 such that the diverter changes position when the timer is complete.

[0039] In some embodiments, the fractionation system 100 is configured to receive a liquid mixture for distillation. In some embodiments, the liquid mixture comprises a compound having the following molecular formula:

[0040]

[0041] where R 1 and R 2Each is independently hydrogen, a straight-chain alkyl group, or a branched-chain alkyl group, and wherein M is a metal. In some embodiments, the metal is tungsten. It should be understood that the fractionation system 100 can be used to distill liquid mixtures having compounds other than the above examples.

[0042] The fractionation system 100 includes conduits 108 fluidly connected to respective vacuum devices. A first vacuum device 118 is fluidly connected to a first one of the conduits 108 disposed at an end 120 of the fractionation head 110. A second vacuum device 122 is fluidly connected to a second one of the conduits 108 disposed at an end 124 of the fractionation head 110. In some embodiments, the second vacuum device 122 is fluidly connected adjacent to the diverter 116. In some embodiments, the conduits 108 are large-bore conduits. In some embodiments, the large-bore conduits include conduits having a diameter sufficient relative to the size of the fractionation system 100 to compensate for degassing. In some embodiments, for a fractionation system 100 having a capacity of 12 L, the large-bore conduits can have a diameter of at least 0.5 inches.

[0043] In some embodiments, the collection container 126 is fluidly connected to the fractionation head 110. In some embodiments, more than one collection container 126 can be included, for example, to collect multiple portions from the liquid mixture being distilled.

[0044] In some embodiments, the pressure relief valve 128 is fluidly connected to the fractionation head 110 at the end 120.

[0045] In some embodiments, multiple conduits 108 fluidly connected to respective vacuum devices can shorten the time required to evacuate the fractionation system 100, which can, for example, reduce the startup time of using the fractionation system 100. In some embodiments, in the example of an interruption in the operation of the vacuum device, the multiple conduits 108 can reduce the amount of time for the vacuum device to recover. In some embodiments, the multiple conduits 108 and being fluidly connected to respective vacuum devices can achieve a stable distillation process without cycling in the distillation rate.

[0046] Figure 2 A flowchart showing a method 150 for fractionation according to some embodiments. In some embodiments, the fractionation system 100 as described can be used to perform the method 150. Figure 1 to perform the method 150.

[0047] At block 152, the method 150 includes obtaining a liquid mixture. In some embodiments, the liquid mixture includes a compound having the following molecular formula:

[0048]

[0049] R 1 and R 2Each is independently hydrogen, a straight-chain alkyl group, or a branched-chain alkyl group. M is a metal. In some embodiments, the metal is tungsten.

[0050] At block 154, method 150 includes separating a liquid mixture by heating the liquid mixture in a distillation vessel (e.g., Figure 1 distillation vessel 102). In some embodiments, the separation includes flowing the vapor of the liquid mixture to contact a column (e.g., Figure 1 column 104) having a mesh (e.g., Figure 1 mesh 106) and flowing through a fractionation head (e.g., Figure 1 fractionation head 110) that is fluidly connected to the column. In some embodiments, the fractionation head includes a timer and a magnetically activated diverter to control the fractionation head. In some embodiments, the timer is used to control the magnetically activated diverter.

[0051] At block 156, method 150 includes collecting a first portion of the separated liquid mixture. Optionally, in some embodiments, a second portion of the separated liquid mixture may be collected. It should be understood that one or more additional portions of the liquid mixture may also be collected.

[0052] In some embodiments, multiple large-bore vacuum devices may be used to evacuate the fractionation system. In some embodiments, including multiple large-bore vacuum devices enables the distillation chamber to be evacuated faster than existing methods.
