TITLE OF THE INVENTIONRECOVERED AND RECLAIMED THERMAL MANAGEMENT FLUID COMPOSITIONSCROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 63 / 627,419, 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, R- 515B has replaced HFC-134a in chillers, but some residual HFC-134a often remains present in the chiller. Therefore, R-515B removed from retrofitted chiller systems or other types of chiller systems which have previously been filled with an HFC-134acontaining composition may contain residual amounts of HFC-134a. Typically, the residual H FC- 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 the difference in boiling points between HFC-134a and HFO-1234ze(E) 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] 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 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

[0006] 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 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, for example in a recovery container or cylinder.

[0007] 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

[0011] Before addressing details of embodiments described below, some terms are defined or clarified.

[0012] As used herein, the term heat transfer composition means a composition used to carry heat from a heat source to a heat sink.

[0013] 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 air- conditioning, 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.

[0014] 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.

[0015] 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 whichprovides heating or cooling of the passenger compartment of an automobile, as well as power electronics, batteries and motors. 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.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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 included in the present inventions. Such intermodal systems include “containers” (combined sea / land transport) as well as “swap bodies” (combined road and rail transport).

[0020] 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. Thesestationary 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.

[0021] 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.

[0022] Additionally, stationary applications may utilize a secondary loop system that uses a primary refrigerant to produce cooling or heating in one location that is transferred to a remote location via a secondary heat transfer fluid.

[0023] The operation cycle of some of these types of heat transfer systems are shown in FIGS. 1-3.

[0024] 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.

[0025] The process that produces waste heat is at least one selected from the group consisting of fuel cells, internal combustion engines, internal compressionengines, 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.

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 ofmaterials 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.

The lubricant may also be between about 0.1 and 20 weight percent of the total composition The lubricant may also be between about 0.1 and 5 weight percent of the total composition.

[0443] 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.

[0444] 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.

[0445] 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.

[0446] 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, or a 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 ormixtures thereof. Preferably the R4 group is an aryl group or an alkyl group. Preferably R1, R2, R3, R4, or any combination thereof are not hydrogen. The R2 groups in a molecule may be the same or different. 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. Exemplary siloxanes that may be used include hexamethyldisiloxane, polydimethylsiloxane, polymethylphenylsiloxane, dodecamethylpentasiloxane, decamethylcyclo-pentasiloxane, decamethyltetrasiloxane, octamethyltrisiloxane, or any combination thereof.

[0447] 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.

[0448] 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 orether 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.

No. 11 / 575,256, published as U.S. Patent Publication 2007 / 0290164, paragraph 42, expressly incorporated herein by reference), such as one or more of: phenyl glycidyl ethers, alkyl glycidyl ethers, alkyleneglycolglycidylethers, cyclohexeneoxides, otolenoxides,or epoxy compounds such as epoxidized soybean oil, and those described by Singh et al. (U.S. patent application Ser. No. 11 / 250,219, published as 20060116310, paragraphs 34-42, expressly incorporated herein by reference).

[0452] Preferred additives include those described in U.S. Pat. Nos. 5,152,926;4,755,316, which are hereby incorporated by reference. In particular, the preferred extreme pressure additives include mixtures of (A) tolyltriazole or substituted derivatives thereof, (B) an amine (e.g. Jeffamine M-600) and (C) a third component which is (i) an ethoxylated phosphate ester (e.g. Antara LP-700 type), or (ii) a phosphate alcohol (e.g. ZELEC 3337 type), or (iii) a Zinc dialkyldithiophosphate (e.g. Lubrizol 5139, 5604, 5178, or 5186 type), or (iv) a mercaptobenzothiazole, or (v) a 2,5-dimercapto-1,3,4-triadiaZole derivative (e. g. Curvan 826) or a mixture thereof. Additional examples of additives which may be used are given in U.S. Pat. No. 5,976,399 (Schnur, 5:12-6:51, hereby incorporated by reference).

[0453] Acid number is measured according to ASTM D664-01 in units of mg KOH / g. 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.

[0454] 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.

The recovered refrigerant may also be stored in a refrigerant tank in the RRR machine until needed for use in another system.

[0481] In some embodiments, at least a portion of any of the compositions of any of the foregoing Embodiments may comprise one or more reclaimed thermal management fluids.

[0482] In some embodiments, any of the compositions of any of the foregoing Embodiments may be collected and stored as a recovered thermal management fluid or a reclaimed thermal management fluid in a storage tank until needed for a further application.

[0483] In some embodiments, the invention relates to a method of reclaiming refrigerant comprising:• removing an unreclaimed refrigerant composition from a heat transfer system, the unreclaimed refrigerant composition having at least a first refrigerant compound and a second refrigerant compound; and• performing at least one treatment selected from transferring, blending, distillation, nitrogen purging, filtration, dehydration, caustic scrubbing, moisture removal, acid removal, oil removal, decanting, composition ratio adjustment and combinations thereof to form a partially reclaimed refrigerant composition or a reclaimed refrigerant composition; and• either storing the partially reclaimed refrigerant composition or a reclaimed refrigerant composition in a container for use in another system or introducing the partially reclaimed refrigerant composition or a reclaimed refrigerant composition back into the heat transfer system, wherein the treatment does not involve separation of the first and second refrigerant compounds.

[0484] In embodiments of this reclamation method, the unreclaimed refrigerant composition is any of the compositions of any of the foregoing Embodiments, and the amounts of the first and second refrigerant compounds are the same in the unreclaimed refrigerant composition and in the partially reclaimed or reclaimed refrigerant compositions. In some embodiments, the unreclaimed refrigerant composition comprises a plurality of refrigerant compounds which are not separated during the treatment, and the amounts of each of the plurality of refrigerant compounds are the same in the unreclaimed refrigerant composition and in the partially reclaimed or reclaimed refrigerant compositions.

[0485] In some embodiments, the reclaiming method further comprise performing an analysis selected from the group consisting of gas chromatography, mass spectrometry, atomic absorption spectroscopy, flame emission spectroscopy, infrared spectroscopy, and combinations thereof on the unreclaimed refrigerant composition to determine the composition of the unreclaimed refrigerant composition sample.

[0486] In some embodiments, the invention relates to a method of recycling refrigerant comprising: removing a spent or used refrigerant composition from a heat transfer system, the spent or used refrigerant composition having at least a first refrigerant compound and a second refrigerant compound; andforming a recycled refrigerant composition; and introducing the recycled refrigerant composition back into the heat transfer system, wherein the treatment does not involve separation of the first and second refrigerant compounds.

[0487] In some embodiments, the recovering to remove the thermal management fluid from a thermal management device is by a recovery system, which may include at least one of a recovery cylinder, a recovery compressor, an air-cooled condenser, a fan, or a combination thereof, from which compressed and condensed refrigerant may be sent for testing for composition and / or impurities or to a recovery tank. The thermal management fluid recovery may be configured to recover a wide variety or only a limited number of thermal management fluids or refrigerant compounds. A recovery system may utilize a single circuit for a single thermal management fluid type or multiple circuits for multiple fluid types.

[0488] In some embodiments, the recycling includes testing the recovered thermal management fluid, purifying the recovered thermal management fluid as needed, adjusting the composition of the recovered thermal management fluid as needed, and / or stabilizing the recovered thermal management fluid as needed. In some embodiments, the recycling includes validating the recycled recovered thermal management fluid as a recycled thermal management fluid.

[0489] In some embodiments, the testing includes determining the composition and / or the amount of organic purity of the recovered thermal management fluid. In some embodiments, a refrigerant analyzer performs the testing. The analyzer determines the composition and purity of the recovered thermal management fluid. In some embodiments, the analyzer determines the type of recovered thermal management fluid and purity as it is being recovered from a thermal management device. The analyzer may alternatively determine the type and purity of a consolidated composition of recovered thermal management fluids. If the analyzed thermal management fluid is determined to be organically pure e.g., 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%) and of a thermal management fluid type by the analyzer, the thermal management fluid may be transferred to an appropriate recycled thermalmanagement fluid tank. If, however, there are impurities (or the organic purity is less than about 95 wt%, or about 96 wt%, or about 97 wt%, or about 98 wt%, or about 99 wt%, or about 99.5 wt%.), such as, air, unknown fluids, or incorrect thermal management fluid, found in the analyzed thermal management fluid by the analyzer, the recovered thermal management fluid may be sent for reclamation. Fluids which contain higher amounts of oil or moisture may be reduced by the RRR equipment to acceptable levels. Again, if refrigerants with high oil, moisture or other contaminants cannot be reduced, the refrigerant may be sent off-site for reclamation.

[0490] In some embodiments, the purifying includes removing one or more impurities from the recovered thermal management fluid. In some embodiments, the purifying includes removing acids, moisture and high boiling residues by, for example, a filter, filter drier, absorbent bed(s) or absorbent column(s). The absorbent may be one or the combination of alumina, molecular sieves, silica gel, zeolites, and the like. In some embodiments, the purifying includes a process to remove NAG.

[0491] If the purity does not meet the appropriate standards for a recycled thermal management fluid after purification, the recovered thermal management fluid may be returned for further purifying or sent to a reclamation site for reclamation.

[0492] Optionally, in some embodiments, the purifying is performed by a regenerator. The regenerator can include at least one of a compressor, a separator, a filter dryer, and may further include at least one of a distiller, a diluter, or a reformulator. In some embodiments, the compressor is driven to circulate the thermal management 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 management 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 management fluid. The regenerator can also determine information on the appropriateness of the oil, water, and acid included in the thermal management fluid after the regeneration processing and compile the thermal management fluid composition, the weight, and the like. After appropriate purification, the thermal management fluid meets AHRI Standard 700 purity specifications.

[0493] In some embodiments, the validating includes confirming that the recovered thermal management fluid has an organic purity greater than about 95 wt%, or about 96 wt%, or about 97 wt%, or about 98 wt%, or about 99 wt%, or about 99.5 wt%, and meets predetermined standards for a recycled thermal management fluid. In the case of thermal management fluids of or including R-134a and / or R-1234yf, the recycled thermal management fluid meets Society of Automotive Engineers (SAE) J2099 standards, which includes less than 1.5 % NAG, by volume, less than 500 ppm (parts per million) by weight high boiling residue, and less than 50 ppm by weight moisture.

[0494] In some embodiments, the recycled and reused thermal management fluid meets the Standard for Specifications for Refrigerants, Air-Conditioning, Heating & Refrigeration Institute (AHRI)(AHRI 700), which is incorporated by reference in its entirety herein. AHRI 700 specifies acceptable levels of contaminants (purity requirements) for fluorocarbon, hydrocarbon, and carbon dioxide refrigerants regardless of source and lists acceptable test methods.

[0516] 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.EXAMPLE 1Performance

[0517] Tables 2-5 show the performance of some exemplary R-410A compositions containing residual refrigerant(s) (HCFC-22 or HFC-134a) as compared with the same compositions without the residual refrigerant(s) in a stationary chiller system and in an Organic Rankine Cycle, as shown in Figs. 1-3. The data are based on the following conditions.ChillerCondenser Mid-Point Temperature 40.6°CCondenser Subcooling O KEvaporator Mid-Point Temperature 5.0°CUseful Superheat 11.1 KCompressor Isentropic Efficiency 0.7Organic Rankine Cycle (ORC)Condenser Temperature 4.4°CEvaporator Temperature 37.8°CExpander Efficiency 0.85Pump Efficiency 0.85Subcooling 3.1 KSuperheat 6.2 KTable 2 Performance of R410A Compositions in Chiller SystemTable 2 (continued) Performance of R410A Compositions in Chiller SystemTable 3Performance of R410A Compositions in Chiller SystemTable 3 (Continued) Performance of R410A Compositions in Chiller SystemTable 4 Performance of R410A Compositions in ORCTable 4Performance of R410A Compositions in ORCTable 5Performance of R410A Compositions in ORCTable 5 (continued) Performance of R410A Compositions in ORC

[0518] Performance of the R-410A compositions containing residual amounts of HCFC-22 or HFC-134a is similar to the R-410A composition which does not contain these residual refrigerants. More particularly, differences in energy efficiency (shown as COP) and capacity among the compositions are de minimis. Thus, the data indicate that the presence of HCFC-22 or HFC-134a as residual refrigerants in R- 410A compositions does not negatively impact performance of the compositions.Impact on Distillation

[0519] Table 6 shows distillation requirements for obtaining an HFC-32 / HFC-125 (e.g., R410A) composition containing up to 0.5 wt.% residual HCFC-22 as compared with obtaining an HFC-32 / HFC-125 (e.g., R410A) composition containing little to no (e.g., 10 ppm) residual HCFC-22. The mass reflux ratio for distilling the latter is more than double that required for a composition that contains up to 0.5 wt.% of the residual refrigerant. Thus, the data show that removing essentially all of the residual refrigerant 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 refrigerant to remain in the composition.Table 6EXAMPLE 2Performance

[0520] Tables 7-10 show the performance of some exemplary R-448A compositions containing residual refrigerant(s) (HCFC-22 or HFC-143a) as compared with the same compositions without the residual refrigerant(s) in a stationary chiller system and in an Organic Rankine Cycle. The data are based on the same conditions as set forth above in Example 1.Table 7Performance of R448A Compositions in Chiller SystemTable 7 (Continued) Performance of R448A Compositions in Chiller SystemTable 8 Performance of R448A Compositions in Chiller SystemTable 8 (Continued) Performance of R448A Compositions in Chiller SystemTable 9 Performance of R448A Compositions in ORCTable 9 (Continued)Performance of R448A Compositions in ORCTable 10 Performance of R448A Compositions in ORCTable 10 (Continued) Performance of R448A Compositions in ORC

[0521] Performance of the R-448A compositions containing residual amounts of HCFC-22 or HFC-143a is similar to the R-448A 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 HCFC-22 or HFC-143a as residual refrigerants in R-448A compositions does not negatively impact performance of the compositions.EXAMPLE 3Performance

[0522] Tables 11-12 show the performance of some exemplary R-515B compositions containing residual refrigerant(s) (CFC-11 or HFC-134a) as compared with the same compositions without the residual refrigerant(s) in a stationary chiller system. The data are based on the same conditions as set forth above in Example 1.Table 11Performance of R515B Compositions in Chiller SystemTable 11 (Continued)Performance of R515B Compositions in Chiller SystemTable 12 Performance of R515B Compositions in Chiller SystemTable 12 (Continued)Performance of R515B Compositions in Chiller System

[0523] Performance of the R-515B compositions containing residual amounts of CFC-11 or HFC-134a is similar to the R-515B composition which does not contain these residual refrigerants. More particularly, differences in energy efficiency (shown as COP) and capacity among the compositions are de minimis or COP and / or capacity are actually increased in some cases. Thus, the data indicate that the presence of CFC-11 or HFC-134a as residual refrigerants in R-515B compositions does not negatively impact performance of the compositions.Impact on Distillation

[0524] Table 13 shows distillation requirements for obtaining an HFC-227ea / E- HFO-1234ze (e.g., R515B) composition containing up to 0.5 wt.% residual HFC-134a as compared with obtaining an HFC-227ea / E-HFO-1234ze (e.g., R515B) composition containing little to no (e.g., 10 ppm) residual HFC-134a. The mass reflux ratio for distilling the latter is significantly higher than that required for a composition that contains up to 0.5 wt.% of the residual refrigerant. Thus, the data show that removing essentially all of the residual refrigerant 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 refrigerant to remain in the composition.Table 13Other Embodiments
