[0001] This application claims the benefit of priority of U.S. Provisional Application 63/541 ,498 filed September 29, 2023, U.S. Provisional Application 63/599,883 filed November 16, 2023, U.S. Provisional Application 63/627,372 filed January 31, 2024, and U.S. Provisional Application 63/564,043 filed March 12, 2024, the disclosure of each of which is incorporated herein by reference it its entirety.

FIELD OF THE INVENTION

[0002] The present disclosure relates to systems and processes of thermal fluid reclamation. More specifically, the present disclosure relates to systems and processes of converting spent thermal fluids into reclaimed azeotropic, azeotropelike, and other close-boiling thermal fluids.

BACKGROUND OF THE INVENTION

[0003] Thermal fluid or refrigerant reclamation has long attracted significant attention due to regulatory requirements and increasing emphasis on circularity, emissions reduction, and resource efficiency. An efficient and effective reclamation process benefits both the environment and the global economy. Indeed, in the absence of such a reclamation process, the thermal fluids would have to be destroyed or otherwise disposed of, such as by thermal oxidation, which is very energy intensive and results in a loss of product to the circular economy.

[0004] Historically, most reclamation processes have simply been achieved by removing contaminants from the thermal fluids and rebalancing the purified blends by addition of components. Historically, where separation has been used, refrigerant reclamation has been limited essentially to single-compound fluids.

[0005] Conventional reclamation requires sending the used refrigerants to a reclamation site for further processing, including purification, which may include drying, acids removal, and/or separation of various components by distillation. During the process, the used refrigerants are often combined in a mixed tank at the reclamation site. Although this simplifies the storage process, it brings challenges and complexity in separation, especially for close-boiling, azeotrope- 1 ike, and azeotropic components in the recovered mixture. For example, to obtain pure closeboiling, azeotrope-like, and azeotropic components, a large separation column may be required, in addition to technical processes such as extraction distillation, all of which may be energy-intensive, labor-intensive, and time-consuming.

[0006] Efficient and effective reclamation of azeotropic, azeotrope-like, and other close-boiling thermal fluids would further benefit both the environment and the global economy.

SUMMARY OF THE INVENTION

[0007] In an example embodiment, a process of thermal fluid reclamation includes combining at least two recovered thermal fluids including a first refrigerant compound and a second refrigerant compound to form a consolidated thermal fluid. The consolidated thermal fluid is a blend including the first refrigerant compound and the second refrigerant compound with a consolidated composition. The process also includes testing the consolidated thermal fluid and validating that the consolidated thermal fluid has greater than about 95 wt%, about 96 wt%, about 97 wt%, about 98 wt%, about 99 wt%, or about 99.5 wt% organic purity. The process further includes treating the consolidated thermal fluid to form a reclaimed thermal fluid. In one embodiment, the treatment comprises distilling the consolidated thermal fluid to form at least one distillate including the first refrigerant compound and the second refrigerant compound as a reclaimed thermal fluid. The reclaimed thermal fluid has a reclaimed composition different from the consolidated composition and the reclaimed thermal fluid is azeotropic, azeotrope-like, or close-boiling. The process yet further includes using or supplying the reclaimed thermal fluid as a thermal fluid product or for formation of a thermal fluid product.

[0008] Other features and advantages of the present invention will be apparent from the following more detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of this disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] FIG. 1 schematically shows a system for reclaiming thermal fluid compositions as azeotropes or azeotrope-like or close-boiling compositions, in accordance with one embodiment of the present invention.

[0010] Wherever possible, the same reference numbers will be used throughout the drawings to represent the same parts.

DETAILED DESCRIPTION OF THE INVENTION

[0011] In exemplary embodiments, an integrated business and engineering process effectively and efficiently recovers multiple used single component thermal fluids and/or multicomponent thermal fluid blends, combines and purifies those recovered fluids, and provides product streams of reclaimed azeotropic, azeotropelike, and/or close-boiling thermal fluids for the manufacture of new product streams that reduces both manufacture of virgin thermal fluids and the need for energy intensive destruction of out-of-specification (conventionally unreclaimable) spent thermal fluids.

[0012] In exemplary embodiments, systems and processes of thermal fluid reclamation combine at least two recovered thermal fluids including at least two refrigerant compounds to form a consolidated thermal fluid. In one embodiment, systems and processes of the present invention involve recovery of a thermal fluid comprised of at least two refrigerant compounds to form a consolidated thermal fluid.

[0013] In one embodiment, at least two recovered thermal fluids are collected from different air conditioning, heating or refrigeration systems, but may comprise the same primary refrigerant compounds or may have the same ASHRAE 34 designation. However, it will be understood by those skilled in the art that, even where the primary refrigerant compounds are the same, slight differences may be present in the compositions of the recovered thermal fluids 10, 12, 14. For example, different minor compounds may be present or absent in the fluids 10, 12, 14, the primary refrigerant compounds may be present in different amounts in the fluids 10, 12, 14, and the like. In other embodiments, the refrigerant compounds contained in each of the recovered thermal fluids are different from each other. [0014] The consolidated thermal fluid is a blend of at least two refrigerant compounds and has a consolidated composition. The systems and processes test the consolidated thermal fluid and validate that the consolidated thermal fluid has greater than about 95 wt%, about 96 wt%, about 97 wt%, about 98 wt%, about 99 wt%, or about 99.5 wt% organic purity. The systems and processes treat the consolidated thermal fluid to form at least one reclaimed thermal fluid. In one embodiment, the treatment comprises distilling the consolidated thermal fluid to form at least one reclaimed thermal fluid. The systems and processes further include analyzing and purifying the reclaimed thermal fluid. The reclaimed thermal fluid has a reclaimed thermal fluid composition different from a consolidated thermal fluid composition of the consolidated thermal fluid and the at least one reclaimed thermal fluid is azeotropic, azeotrope-like, or close-boiling.

Hence, during boiling or evaporation, the vapor and liquid compositions, if they change at all, change only to a minimal or negligible extent. In contrast, the vapor and liquid compositions of non-azeotrope-like compositions change to a substantial degree during boiling or evaporation.

[0018] As used herein, "azeotrope-like behavior" refers to a behavior exhibiting dew point pressure and bubble point pressure with virtually no pressure differential. In some embodiments, the difference in the dew point pressure and bubble point pressure at a given temperature is 10% or less, alternatively 9% or less, alternatively 8% or less, alternatively 7% or less, alternatively 6% or less, alternatively 5% or less, alternatively 4% or less, alternatively 3% or less, alternatively 2% or less, alternatively 1% or less, or any value, range, or sub-range therebetween.

[0019] As used herein, “close-boiling composition” refers to compositions including at least two refrigerant compounds having a boiling point difference within about 20°C, or within about 18°C, or within about 15°C, or within about 12°C, or within about 10°C. In some embodiments, the boiling point difference is less than about 9°C, alternatively less than about 8°C, alternatively less than about 7°C, alternatively less than about 6°C, alternatively less than about 5°C, alternatively less than about 4°C, alternatively less than about 3°C, alternatively less than about 2°C, or any value, range, or sub-range therebetween.

[0020] As used herein, “virgin thermal fluid” refers to a thermal fluid composition having at least about 95 wt% organic purity, preferably at least about 99 wt% organic purity, most preferably at least about 99.5 wt% organic purity, and that has not yet been used in a thermal fluid application.

[0021] As used herein, “used thermal fluid” refers to a thermal fluid composition having at least about 95 wt% organic purity, preferably at least about 99 wt% organic purity, most preferably at least about 99.5 wt% organic purity, and that has been used as a thermal fluid.

[0022] As used herein, “spent thermal fluid” refers to a thermal fluid composition having less than about 95 wt% organic purity, preferably less than about 99 wt% organic purity, most preferably less than about 99.5 wt% organic purity, and that has been used as a thermal fluid.

[0023] As used herein, “recovered thermal fluid” refers to a spent thermal fluid or a used thermal fluid composition drained or otherwise removed from a thermal management device, such as, for example, a refrigeration, an air-conditioning system or a heat pump.

[0024] As used herein, “consolidated thermal fluid composition” refers to a blend formed by combining two or more different recovered thermal fluid types.

[0025] As generally used herein, “reclaimed thermal fluid” refers to a thermal fluid having at least about 95 wt% organic purity, preferably at least about 99 wt% organic purity, most preferably at least about 99.5 wt% organic purity and meeting conventional specifications for commercial use or sale as a thermal fluid. In some embodiments, “reclaimed thermal fluid”, as used herein, refers to a distillation product of a consolidated thermal fluid having at least about 95 wt% organic purity, preferably at least about 99 wt% organic purity, most preferably at least about 99.5 wt% organic purity and meeting conventional specifications for commercial use or sale as a thermal fluid.

[0026] As used herein, “partially reclaimed thermal fluid” refers to a thermal fluid which comprises, at least in part, a reclaimed thermal fluid.

[0027] As used herein, “organic purity” refers to the degree to which a fluid or fluid composition is free of contaminants such as oil and inorganic materials, such as water, acid, non-absorbable gases (NAGs), particulates/solids, and the like.

[0028] In some embodiments, “virgin thermal fluid”, “used thermal fluid”, “spent thermal fluid”, “recovered thermal fluid”, “consolidated thermal fluid composition”, “partially reclaimed fluid” and/or “reclaimed thermal fluid”, as used herein, refer to a thermal fluid composition as each is defined above, and optionally further comprising at least one stabilizer, particularly when the thermal fluid composition includes an HFO refrigerant compound, such as R-1234yf. In some embodiments, the stabilizer comprises at least one inhibitor compound that inhibits, if not eliminates, a fluoroethylene from interacting with another compound and forming dimers, oligomers, homopolymers, or polymeric products. In some embodiments, the at least one inhibitor is selected from hydrocarbons such as cyclic monoterpenes (e.g., limonene, pinene, a-pinene, p-pinene, and terpinene); lipophilic organic compounds such as tocopherols (e.g., a-tocopherol) or butylated hydroxytoluene (BHT); phenols or aromatic organic compounds having at least one chemical moiety -C6H4(OH) (e.g., benzene-1,4-diol, 4-methoxyphenol); and mixtures thereof.

[0029] In another embodiment, the stabilizer comprises an acid scavenger, such as, but not limited to, hindered amines and epoxy compounds such as epoxy butene. In one embodiment, the thermal fluid composition of any of a “virgin thermal fluid”, “used thermal fluid”, “spent thermal fluid”, “recovered thermal fluid”, “consolidated thermal fluid composition”, “partially reclaimed fluid” and/or “reclaimed thermal fluid”, each as defined above, comprises at least one refrigerant compound, such as an HFO or HFC refrigerant compound, and at least one stabilizer comprising at least one acid scavenger, such as, but not limited to, hindered amines and epoxy compounds such as epoxy butene.

[0030] Further details of the optional stabilizer are provided herein.

[0031] FIG. 1 shows a system for reclaiming thermal fluid compositions from three different recovered thermal fluids 10, 12, 14. It will be understood by those skilled in the art that the present invention is not limited to three recovered thermal fluids, but instead encompasses a lesser number or a greater number of recovered thermal fluids.

[0032] The three different recovered thermal fluids 10, 12, 14 are combined and mixed together in a consolidation tank 16 to form a consolidated thermal fluid of a consolidated composition of at least two different refrigerant compounds. Each recovered thermal fluid 10, 12, 14 may be of a single refrigerant compound or a blend of two or more refrigerant compounds. In some embodiments, the system may contain multiple consolidation tanks 16, and what refrigerant compounds are in each recovered thermal fluids 10, 12, 14 is known or determined prior to adding the recovered thermal fluids 10, 12, 14 to the consolidation tank 16, where a recovered thermal fluid 10, 12, 14 is added to a selected consolidation tank 16 based on the refrigerant compounds in the recovered thermal fluid 10, 12, 14. The recovered thermal fluids may be individually tested and/or validated for organic purity, but preferably the consolidated thermal fluid is tested and/or validated for organic purity.

[0033] In one embodiment, the recovered thermal fluids and/or the consolidated thermal fluid is/are tested to determine the composition, water content, NAG content, acidity content, and/or the organic purity.

[0034] In one embodiment, the recovered thermal fluids and/or the consolidated thermal fluid is/are validated or treated, such as by purifying as needed for water content, NAG content, acidity content, and/or removing one or more impurities to achieve an organic purity of at least about 95 wt%, or about 96 wt%, or about 97 wt%, or about 98 wt%, or about 99 wt%, or about 99.5 wt%.

[0035] The tested and validated consolidated thermal fluid may then be further treated (e.g., distilled) as needed to form a reclaimed thermal fluid or a blending component for formation of a reclaimed or partially reclaimed thermal fluid (also sometimes referred to herein as a reclaimed thermal fluid building block or blend constituent), or may be suitable for use as-is as a reclaimed thermal fluid or as a reclaimed thermal fluid building block.

[0036] More particularly, in one embodiment, the tested and validated (also referred to herein as treated) consolidated thermal fluid is fed as needed to at least one distillation column or other appropriate distillation system 18, from which one or more distillate fractions are collected and stored in respective reclaimed storage tanks until needed for a further application. In one embodiment, as shown in FIG. 1 , four fractions 20, 22, 24, 26 of distillates are collected from the distillation system 18 and stored as reclaimed thermal fluids in reclaimed storage tanks 30, 32, 34, 36, respectively, one for each reclaimed thermal fluid composition, until needed for a further application. It will be understood by those skilled in the art that that while the description herein primarily refers to the four reclaimed thermal fluid compositions 20, 22, 24, 26 of the exemplary embodiment of FIG. 1 , the invention applies to any number of collected distillate fractions and any number of reclaimed thermal fluid compositions and is not limited to four such fractions and compositions as shown in FIG. 1.

[0037] At least one of the reclaimed thermal fluids 20, 22, 24, 26 is azeotropic, azeotrope-like, or a close-boiling composition of two or more refrigerant compounds. Alternatively, in some embodiments, two, three, or all of the reclaimed thermal fluids 20, 22, 24, 26 are azeotropic, azeotrope- 1 ike, or close-boiling compositions of two or more refrigerant compounds. The system may operate on a continuous, batch, or semi-batch basis.

[0038] In another embodiment, the tested and validated (also referred to herein as treated) consolidated thermal fluid is not subjected to distillation or other processing, and instead may be stored as-is as a reclaimed thermal fluid in one or more reclaimed storage tanks until needed for a further application, as will be described in further detail herein. For example, referring to Fig. 1, the distillation system 18, if present, may be bypassed, and the tested and validated consolidated thermal fluid 16 may be stored as-is as a reclaimed thermal fluid 24 in one or more reclaimed storage tanks (e.g., storage tank 34) until needed for a further application. In one embodiment, the reclaimed thermal fluid is azeotropic, azeotrope-like, or a closeboiling composition of two or more refrigerant compounds.

[0039] The discussion of the reclaimed thermal fluids 20, 22, 24, 26 and the reclaimed storage tanks 30, 32, 34, 36 provided herein refers to the various embodiments disclosed herein. For example, the reclaimed thermal fluids 20, 22, 24, 26 may have been formed without distillation and stored in the reclaimed storage tanks 30, 32, 34, 36 or may have been formed as a result of distillation system 18 and stored in the reclaimed storage tanks 30, 32, 34, 36.

[0040] The reclaimed thermal fluids 20, 22, 24, 26 in the reclaimed storage tanks 30, 32, 34, 36 may each individually be subjected to a final purification and analysis to confirm their composition and that they are commercial grade. The final purification and analysis may include analyzing and purifying as needed for water content, NAG content, acidity content of other impurities, and/or organic purity.

[0041] In some embodiments, all or a portion of an azeotropic, azeotrope- 1 ike, or close-boiling reclaimed thermal fluid 20, 22, 24, 26 may be packaged and sold as a reclaimed thermal fluid building block, such as for forming commercial thermal fluid blends. For example, as shown in FIG. 1, all or a portion of an azeotropic, azeotrope-like, or close-boiling reclaimed thermal fluid 24 may be packaged and sold as a reclaimed thermal fluid building block 40, such as for forming commercial thermal fluid blends. [0042] In some embodiments, all or a portion of an azeotropic, azeotrope- 1 ike, or close-boiling reclaimed thermal fluid 20, 22, 24, 26 may be combined with all or a portion of a virgin, a used, or other reclaimed thermal fluid(s) sharing the same refrigerant compounds to adjust their composition ratios, such as to make an azeotropic or zeotropic composition or azeotropic or zeotropic commercial thermal fluid blend. For example, as shown in FIG. 1, all or a portion of an azeotropic, azeotrope-like, or close-boiling reclaimed thermal fluid 24 may be combined with all or a portion of a virgin, a used, or other reclaimed thermal fluid(s) 42 sharing the same refrigerant compounds to adjust their composition ratios, such as to make an azeotropic or zeotropic composition or azeotropic or zeotropic commercial thermal fluid blend 44.

[0043] In some embodiments, all or a portion of an azeotropic, azeotrope- 1 ike, or close-boiling reclaimed thermal fluid 20, 22, 24, 26 may be combined with all or a portion of a virgin, a used, or other reclaimed thermal fluid(s) having at least one additional refrigerant compound to make an azeotropic or zeotropic composition or azeotropic or zeotropic commercial thermal fluid blend. For example, as shown in FIG. 1 , all or a portion of an azeotropic, azeotrope-like, or close-boiling reclaimed thermal fluid 24 may be combined with all or a portion of a virgin, a used, or other reclaimed thermal fluid(s) 46 having at least one additional refrigerant compound, such as an HFO or HFC, to make an azeotropic or zeotropic composition or azeotropic or zeotropic commercial thermal fluid blend 48.

[0044] In some embodiments, the system of the present invention may be located at a site separate and distinct from the site of a blending facility or a refrigerant manufacturing facility which produces virgin material or may be co-located with a blending facility or refrigerant manufacturing facility.

[0045] Other systems may be designed and constructed to include other numbers and combinations of different recovered thermal fluids and produce other numbers of different reclaimed thermal fluids. The types of reclaimed thermal fluids may be the same or different from the types of recovered fluids.

[0046] In some embodiments, a consolidation tank receives at least a portion of each of the types of recovered thermal fluids, such that the consolidation tank includes some or all of the refrigerant compounds present in the system. Some systems may have more than one consolidation tank, where additional consolidation tanks receive more than one but not all of the types of recovered thermal fluids and contain more than one but not necessarily all of the refrigerant compounds present in the system. In exemplary embodiments, each consolidation tank includes at least two refrigerant compounds. The types of recovered thermal fluids directed to a consolidation tank may be selected based on the refrigerant compounds that they include and the refrigerant compounds in the reclaimed thermal fluid to be formed from the consolidated thermal fluid.

[0047] In exemplary embodiments, when the reclaimed thermal fluid includes at least one HFO refrigerant compound, the reclamation process includes adding a stabilizer package to the thermal fluid. In exemplary embodiments, the stabilizer package includes an effective amount of at least one inhibitor such that the thermal fluid remains substantially free of oligomeric, homopolymeric, or other polymeric products derived from the thermal fluid. In some embodiments, at least one inhibitor is selected from hydrocarbons such as cyclic monoterpenes (e.g., limonene, pinene, a-pinene, p-pinene, and terpinene); lipophilic organic compounds such as tocopherols (e.g., a-tocopherol) or butylated hydroxytoluene (BHT); phenols or aromatic organic compounds having at least one chemical moiety -C6H4(OH) (e.g., benzene-1,4-diol, 4-methoxyphenol); and mixtures thereof. Specific examples of inhibitor compounds may include at least one member selected from limonene (particularly D-limonene), a-terpinene, pinene, a-pinene, p-pinene, a-tocopherol, butylated hydroxytoluene (BHT), 4-methoxyphenol, benzene-1,4-diol, and mixtures thereof. In one embodiment, the inhibitor composition includes a liquid at a temperature from about -80°C to about 180°C, about -70°C to about 170°C, and in some cases about -60°C to about 160°C. By “stabilized” it is meant to refer to a composition including an effective amount of at least one inhibitor compound that inhibits, if not eliminates, a fluoroethylene from interacting with another compound and forming dimers, oligomers, homopolymers, or polymeric products.

[0048] In some embodiments, the stabilizer package further comprises at least one acid scavenger. Examples of the acid scavengers that may be included in the present compositions include, but are not limited to, the stabilizers and/or the epoxide component of the stabilizers disclosed in U.S. Patent No. 8,535,555 and the acid scavengers disclosed in International Application Publication No. WO 2020/222864, the disclosure of each of which is incorporated herein by reference in its entirety.

[0049] In some embodiments, the acid scavenger may comprise one or more epoxides, one or more amines and/or one or more hindered amines, such as, for example but not limited to, epoxybutane.

[0050] In some embodiments, an analyzer determines the composition and organic purity of one or more of the thermal fluids of the system and process. In some embodiments, the analyzer determines the type of recovered thermal fluid and organic purity as it is being recovered from a thermal management device. The analyzer may alternatively determine the type and organic purity of the consolidated thermal fluid and/or the reclaimed thermal fluid. If the analyzed thermal fluid is determined to be organically pure (>95 wt%, or >96 wt%, or >97 wt%, or >98 wt%, or >99 wt%, or >99.5 wt%) and of a single type by the analyzer, the thermal fluid may be transferred to an appropriate recovery tank. If, however, there are impurities (or the organic purity is less than 95 wt%, or 96 wt%, or 97 wt%, or 98 wt%, or 99 wt%, or 99.5 wt%), such as, oil, water, dirt, and/or acid, found in the analyzed thermal fluid by the analyzer, the analyzed thermal fluid may be sent to a regenerator for reprocessing.

[0051] In some embodiments, a regenerator purifies the recovered thermal fluid, the consolidated thermal fluid and/or the reclaimed thermal fluid to a state that meets AHRI Standard 700 purity specifications. The regenerator can include at least a compressor, a separator, a filter dryer, and may further include a distiller, a diluter, or a reformulator. In some embodiments, the compressor is driven to circulate the thermal fluid in a refrigerant circuit such that a voltage is applied to reduce or remove oil, such as the refrigerating machine oil, in the thermal fluid. In some embodiments, the separator is a type of oil separator. In some embodiments, the filter dryer reduces or removes water and acid included in the thermal fluid. The regenerator can also determine information on the appropriateness of the oil, water, and acid included in the thermal fluid after the regeneration processing and compile the thermal fluid composition, the weight, and the like.

[0052] In some embodiments, the reclaimed thermal fluid is selected from, and meets the standards of, Standard for Specifications for Refrigerants, Air- Conditioning, Heating & Refrigeration Institute (AHRI), (AHRI 700), which is incorporated by reference in its entirety herein. AHRI 700specifies acceptable levels of contaminants (purity requirements) for fluorocarbon, hydrocarbon, and carbon dioxide refrigerants regardless of source and lists acceptable test methods. These refrigerants are as referenced in the ANSI/American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 34 with Addenda, which is also incorporated by reference in its entirety herein. The compositions of certain blends can be found in “Factsheet 1 : Update on New Refrigerants Designations and Safety Classifications”, ASHRAE, April 2023; or at https://www.ashrae.org/technical-resources/standards-and-guidelines/ashrae- refrigerant-designations; or in ISO 817 (International Organization for Standardization), each of which is incorporated by reference in its entirety herein.
