Description

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 63 / 627,393, filed on January 31,2024, the disclosure of which is herein incorporated by reference in its entirety. FIELD OF THE INVENTION

[0002] The present disclosure relates to recovered and reclaimed thermal management fluid compositions, as well as to systems containing the same and processes of thermal management fluid recovery and reclamation. More specifically, the present disclosure relates to thermal management fluid compositions which have been recovered from a heat transfer system, as well as to uses thereof in heat transfer systems, methods of recovery of the same, methods of reclamation of the same, methods of using the same, and storage of the same. BACKGROUND OF THE INVENTION

[0003] Recovery and reclamation of thermal management fluids has long attracted significant attention, due to regulatory requirements and increasing emphasis on circularity, emissions reduction, and resource efficiency. As the regulatory landscape evolved, thermal management fluids have undergone multiple transitions. For example, ozone depleting chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) were phased out as a result of the Montreal Protocol, and were initially replaced by hydrofluorocarbons (HFCs) and ultimately by hydrofluoroolefins (HFOs) for use as refrigerants, solvents, fire extinguishing agents, blowing agents and propellants.

[0004] With each transition, thermal management fluid reclamation becomes more complicated as more molecules are introduced into the process. For example, HFO-1234yf has replaced HFC-134a in automobile air conditioners, but some residual HFC-134a often remains present in the system. Therefore, HFO-1234yf recovered from retrofitted automobile air conditioner systems may contain residual amounts of HFC-134a. Typically, the residual HFC-134a is removed during the reclamation process. However, it is energy-intensive, labor-intensive, and time-consuming to completely remove HFC-134a in the reclamation process, because HFC-134a forms an azeotrope with HFO-1234yf under certain temperature and pressure conditions, and also because the difference in boiling points between HFC-134a and HFO-1234yf is less than 10°C. Thus, it is difficult to separate the compounds from each other in the reclaiming process. Further, separating such close-boiling or azeotropic thermal management fluids also results in a large environmental footprint, since large separation columns, extractive distillation and the like are needed. Such challenges and complexities in separation may arise with many recovered thermal management fluids.

[0005] Such challenges and complexities also arise in processes of distilling a single refrigerant compound from a refrigerant blend. For example, distilling R-515B to separate HFO-1234ze(E) from HFC-227ea can be costly and energy and labor intensive, and involves a large environmental footprint, since large separation columns, extractive distillation and the like are needed to separate the HFO from the blend.

[0006] There is a need for refrigerant compositions that not only meet low ODP standards and have low global warming potentials and meet the standards of evolving regulations, but that also can be reclaimed or distilled in a manner which is efficient in terms of costs, energy and time, minimizes environmental footprint, and provides compositions exhibiting equivalent or superior performance in a variety of applications. SUMMARY OF THE INVENTION

[0007] In certain aspects, the invention relates to thermal management fluid compositions, particularly recovered, recycled or reclaimed thermal management fluid compositions, which comprise at least one residual refrigerant. The invention also relates to systems containing the same and processes of thermal management fluid recovery and reclamation. In certain aspects, the invention relates to such thermal management fluid compositions which have been recovered from a heat transfer systems, as well as to uses thereof in heat transfer systems, methods of recovery of the same, methods of reclamation of the same, methods of using the same, and storage of the same, for example in a recovery container or cylinder. In some aspects, the invention relates to thermal management fluid compositions which are reprocessed products, such as distillation products, and which comprise at least one residual refrigerant.

[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

[0012] Before addressing details of embodiments described below, some terms are defined or clarified.

[0013] As used herein, the term heat transfer composition means a composition used to carry heat from a heat source to a heat sink.

[0014] A heat source is defined as any space, location, object or body from which it is desirable to add, transfer, move or remove heat, more particularly any space, location, object or body from which it is desirable to remove heat. Examples of heat sources is spaces (open or enclosed) requiring refrigeration or cooling, such as refrigerator or freezer cases in a supermarket, building spaces requiring airconditioning, industrial water chillers or the passenger compartment of an automobile requiring air-conditioning. In some embodiments, the heat transfer composition may remain in a constant state throughout the transfer process (i.e., not evaporate or condense). In other embodiments, evaporative cooling processes may utilize heat transfer compositions as well.

[0015] A heat sink is defined as any space, location, object or body capable of absorbing heat. For example, a vapor compression refrigeration system is one example of a system that utilizes both a heat source and a heat sink to operate, with the heat sink being the component into which heat is rejected from the condenser of the vapor compression system.

[0016] A heat transfer system is the system (or apparatus) used to produce a heating or cooling effect in a particular space. A heat transfer system may be a mobile system or a stationary system. In some embodiments related to automotive applications, a heat transfer system implies the heating or cooling system which provides heating or cooling of the passenger compartment of an automobile. Sometimes this system is called a heat pump system and may be a reversible heating system or a reversible cooling system, or simply a heating and cooling system.

[0017] In some embodiments, the disclosed compositions may function as primary refrigerants in secondary loop systems that provide cooling to remote locations by use of a secondary heat transfer fluid, which may comprise water, an aqueous salt solution (e.g., calcium chloride), a glycol, carbon dioxide, or a fluorinated hydrocarbon fluid. In this case the secondary heat transfer fluid is the body to be cooled as it is adjacent to the evaporator and is cooled before moving to a second remote body to be cooled.

[0018] Examples of heat transfer systems included but are not limited to air conditioners, freezers, refrigerators, heat pumps, water chillers, flooded evaporator chillers, direct expansion chillers, walk-in coolers, supermarket systems, heat pumps, mobile refrigerators, mobile air conditioning units and combinations thereof.

[0019] More particularly, examples of air conditioning or heat pump systems include but are not limited to air conditioners, residential heat pumps, chillers, including flooded evaporator chillers and direct expansion chillers, mobile air conditioning units, dehumidifiers, and combinations thereof.

[0020] As used herein, mobile refrigeration, air conditioning or heat pump systems refers to any refrigeration, air conditioner or heat pump apparatus incorporated into a transportation unit for the road, rail, sea or air. Mobile air conditioning or heat pumps systems may be used in automobiles, trucks, railcars or other transportation systems. Mobile refrigeration may include transport refrigeration in trucks, airplanes, or rail cars. In addition, apparatus which are meant to provide refrigeration for a system independent of any moving carrier, known as “intermodal” systems, are including in the present inventions. Such intermodal systems include “containers” (combined sea / land transport) as well as “swap bodies” (combined road and rail transport).

[0021] As used herein, stationary air conditioning or heat pump systems are systems that are fixed in place during operation. A stationary air conditioning or heat pump system may be associated within or attached to buildings of any variety. These stationary applications may be stationary air conditioning and heat pumps, including but not limited to chillers, heat pumps, including residential and high temperature heat pumps, residential, commercial or industrial air conditioning systems, and including window, ductless, ducted, packaged terminal, and those exterior but connected to the building such as rooftop systems.

[0022] Examples of refrigeration systems the disclosed compositions may be useful in are equipment including commercial, industrial or residential refrigerators and freezers, ice machines, self-contained coolers and freezers, flooded evaporator chillers, direct expansion chillers, walk-in and reach-in coolers and freezers, and combination systems. In some embodiments, the disclosed compositions may be used in supermarket refrigeration systems.

[0023] Additionally, stationary applications may utilize a secondary loop system that uses a primary refrigerant to produce cooling in one location that is transferred to a remote location via a secondary heat transfer fluid.

[0024] The operation cycle of some of these types of heat transfer systems are shown in FIGS. 1-3.

[0025] Organic Rankine Cycle (ORC) systems are often used to recover waste heat from industrial processes. In combined heat and power (cogeneration) applications, waste heat from combustion of fuel used to drive the prime mover of a generator set is recovered and used to make hot water for building heat, for example, or for supplying heat to operate an absorption chiller to provide cooling. In some cases, the demand for hot water is small or does not exist. The most difficult case is when the thermal requirement is variable and load matching becomes difficult, confounding efficient operation of the combined heat and power system. In such an instance, it is more useful to convert the waste heat to shaft power by using an organic Rankine cycle system. The shaft power can be used to operate pumps, for example, or it may be used to generate electricity. By using this approach, the overall system efficiency is higher and fuel utilization is greater. Air emissions from fuel combustion can be decreased since more electric power can be generated for the same amount of fuel input.

[0026] The process that produces waste heat is at least one selected from the group consisting of fuel cells, internal combustion engines, internal compression engines, external combustion engines, and turbines. Other sources of waste heat can be found in association with operations at oil refineries, petrochemical plants, oil and gas pipelines, chemical industry, commercial buildings, hotels, shopping malls, supermarkets, bakeries, food processing industries, restaurants, paint curing ovens, furniture making, plastics molders, cement kilns, lumber kilns (drying), calcining operations, steel industry, glass industry, foundries, smelting, air-conditioning, refrigeration, and central heating.

[0040] As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0041] The transitional phrase "consisting of" excludes any element, step, or ingredient not specified. If in the claim such would close the claim to the inclusion of materials other than those recited except for impurities ordinarily associated therewith. When the phrase "consists of' appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole.

[0042] The transitional phrase "consisting essentially of" is used to define a composition, method that includes materials, steps, features, components, or elements, in addition to those literally disclosed provided that these additional included materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the claimed invention, especially the mode of action to achieve the desired result of any of the processes of the present invention. The term 'consisting essentially of occupies a middle ground between “comprising” and 'consisting of.

[0043] Where applicants have defined an invention or a portion thereof with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description should be interpreted to also include such an invention using the terms “consisting essentially of’ or “consisting of” including, for example, a composition consisting essentially of or consisting of.

[0044] Also, use of “a” or “an” are employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one or at least one and the singular also includes the plural unless it is obvious that it is meant otherwise.

[0411] In one aspect of the invention, the inventive refrigerant composition is used to introduce lubricant into the A / C system as well as or alternatively other additives, such as a) acid scavengers, b) performance enhancers, and c) flame suppressants. In one preferred embodiment, the present compositions comprise an acid scavenger.

[0412] Examples of the acid scavengers that may be included in the present compositions include, but are not limited, 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.

[0413] In some embodiments, an 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.

[0414] In some embodiments, an acid scavenger may comprise a siloxane, an activated aromatic compound, or a combination of both. Serrano et al (paragraph 38 of US 2011 / 0272624 A1), which is hereby incorporated by reference, discloses that the siloxane may be any molecule having a siloxyfunctionality. The siloxane may include an alkyl siloxane, an aryl siloxane, ora siloxane containing mixtures of aryl and alkyl substituents. For example, the siloxane may be an alkyl siloxane, including a dialkylsiloxane or a polydialkylsiloxane. Preferred siloxanes include an oxygen atom bonded to two silicon atoms, i.e., a group having the structure: SiOSi. For example, the siloxane may be a siloxane of Formula IV: R1[Si(R2R3)4O]nSi(R2R3)R4, where n is 1 or more. Siloxanes of Formula IV have n that is preferably 2 or more, more preferably 3 or more, (e.g., about 4 or more). Siloxanes of formula IV have n that is preferably about 30 or less, more preferably about 12 or less, and most preferably about 7 or less. Preferably the R4 group is an aryl group or an alkyl group. Preferably the R2 groups are aryl groups or alkylgroups or mixtures thereof. Preferably the R3 groups are aryl groups or alkyl groups or mixtures thereof.

Preferably the R2 groups in a molecule are the same. The R2 groups in a molecule may be the same or different from the R3 groups. Preferably, the R2 groups and R3 groups in a molecule are the same. Preferred siloxanes include siloxanes of Formula IV, wherein R1, R2, R3, R4, R5, or any combination thereof is a methyl, ethyl, propyl, or butyl group, or any combination thereof.

[0415] Incorporated by previous reference from Serrano et al paragraph notes that in one aspect of the invention, the siloxane is an alkylsiloxane containing from about 1 to about 12 carbon atoms, such as hexamethyldisiloxane. The siloxane may also be a polymer such as polydialkylsiloxane, Where the alkyl group is a methyl, ethyl, propyl, butyl, or any combination thereof. Suitable polydialkylsiloxanes have a molecular weight from about 100 to about 10,000. Highly preferred siloxanes include hexamethyldisiloxane, polydimethylsiloxane, and combinations thereof. The siloxane may consist essentially of polydimethylsiloxane, hexamethyldisoloxane, or a combination thereof.

[0416] The activated aromatic compound may be any aromatic molecule activated towards a Friedel-Crafts addition reaction, or mixtures thereof. An aromatic molecule activated towards a Friedel-Crafts addition reaction is defined to be any aromatic molecule capable of an addition reaction with mineral acids. Especially aromatic molecules capable of addition reactions with mineral acids either in the application environment (AC system) or during the ASHRAE 97: 2007 “Sealed Glass Tube Method to Test the Chemical Stability of Materials for Use within Refrigerant Systems” thermal stability test. Such molecules or compounds are typically activated by substitution of a hydrogen atoms of the aromatic ring with one of the following groups: NH2, NHR, NRz, ADH, AD, NHCOCH3, NHCOR, 4OCH3, OR, CH3, 4C2H5, R, or C6H5, where R is a hydrocarbon (preferably a hydrocarbon containing from about 1 to about 100 carbon atoms). The activated aromatic molecule may be an alcohol, or an ether, where the oxygen atom (i.e., the oxygen atom of the alcohol or ether group) is bonded directly to an aromatic group. The activated aromatic molecule may be an amine Where the nitrogen atom (i.e., the nitrogen atom of the amine group) is bonded directly to an aromatic group. By way of example, the activated aromatic molecule may have the formula ArXRn, Where X is O (i.e., oxygen) or N (i.e., nitrogen); n:1 When X:O; n:2 When x:N; Ar is an aromatic group (i.e., group, C6H5); R may be H or a carbon containing group; and When n:2, the R groups may be the same or different. For example, R may be H (i.e., hydrogen), Ar, an alkyl group, or any combination thereof, Exemplary activated aromatic molecules that may be employed in a refrigerant composition according to the teachings herein include diphenyl oxide (i.e., diphenyl ether), methyl phenyl ether (e.g., anisole), ethyl phenyl ether, butyl phenyl ether or any combination thereof. One highly preferred aromatic molecule activated to Wards a Friedel-Crafts addition reaction is diphenyl oxide.

The total halides concentration, the fluorine ion concentration, and the total organic acid concentration is measured by ion chromatography. Chemical stability of the refrigerant system is measured according to ASHRAE 97: 2007 (RA 2017) “Sealed Glass Tube Method to Test the Chemical Stability of Materials for Use within Refrigerant Systems”. The viscosity of the lubricant is tested at 40°C according to ASTM D-7042.

[0422] Mouli et al. (WO 2008 / 027595 and WO 2009 / 042847) teach the use of alkyl silanes as a stabilizer in refrigerant compositions containing fluoroolefins. Phosphates, phosphites, epoxides, and phenolic additives also have been employed in certain refrigerant compositions. These are described for example by Kaneko (U.S. patent application Ser. No. 11 / 575,256, published as U.S. Publication 2007 / 0290164) and Singh etal. (U.S. patent application Ser. No. 11 / 250,219, published as U.S. Publication 2006 / 0116310).

EXAMPLES

[0479] It has been found that the presence of residual refrigerants, as defined and described herein, in any of the compositions of any of the foregoing Embodiments, not only avoids the need for complex and costly separation processes and equipment, such as large separation columns, extractive distillation and the like, and thus minimizes environmental footprint, for example for a reclamation process, but also does not negatively impact performance of the compositions and, in some cases, actually enhances performance, for example in terms of capacity and / or coefficient of performance, as demonstrated in the Examples.

[0480] The modeled cycles presented in the Examples were performed using physical properties from NIST Refprop and thermodynamic calculations. Example 1

[0482] Performance of the HFO-1234yf compositions containing one or more of the residual refrigerants is similar to the HFO-1234yf composition which does not contain these residual refrigerants. More particularly, differences in capacity among the compositions are de minimis and the energy efficiency (shown as COP) increases slightly for compositions containing the residual refrigerants. Thus, the data indicate that the presence of CFC-12, HFC-134a, HFC-32 and / or E-HFO-1234ze as residual refrigerants in HFO-1234yf compositions does not negatively impact performance of the compositions. Impact on Distillation

[0483] Tables 8 and 9 show distillation requirements for obtaining an HFO-1234yf composition containing up to 0.5 wt.% residual HFC-134a or up to 0.5 wt.% residual CFC-12, as compared with obtaining an HFO-1234yf composition containing little to no (e.g., 10 ppm) residual HFC-134a or CFC-12. The mass reflux ratio for distilling the latter is significantly higher than required for a composition that contains up to 0.5 wt.% of the residual refrigerants. Thus, the data show that removing essentially all of the residual refrigerants from the composition would require a significantly larger distillation column and higher energy input, and thus exhibit a much larger environmental footprint, as compared with allowing up to 0.5 wt.% of the residual refrigerants to remain in the composition.

[0485] Performance of the HFC-134a compositions containing one or more of the residual refrigerants is similar to or better than the HFC-134a composition which does not contain these residual refrigerants. More particularly, differences in capacity among the compositions are de minimis and the energy efficiency (shown as COP) increases slightly for compositions containing the residual refrigerants. Thus, the data indicate that the presence of CFC-12, HFO-1234yf and / or HCFC-22 as residual refrigerants in HFC-134a compositions does not negatively impact performance of the compositions. IMPACT ON DISTILLATION

[0486] Tables 14 and 15 show distillation requirements for obtaining an HFC-134a composition containing up to 0.5 wt.% residual CFC-12 or up to 0.5 wt.% residual HFO-1234yf, as compared with obtaining an HFC-134a composition containing little to no (e.g., 10 ppm) residual CFC-12 or HFO-1234yf. The mass reflux ratio for distilling the latter is significantly higher than required for a composition that contains up to 0.5 wt.% of the residual refrigerants. Thus, the data show that removing essentially all of the residual refrigerants from the composition would require a significantly larger distillation column and higher energy input, and thus exhibit a much larger environmental footprint, as compared with allowing up to 0.5 wt.% of the residual refrigerants to remain in the composition.
