Definitions

  • Refrigerators, food freezers, air conditioners and the like except those that are motorless, have compressors which compress the refrigerant.
  • the most commonly used refrigerants are those which are immiscible with the lubricant, such as ammonia. sulfur dioxide and the like and those which are miscible with the lubricant, such as halogen type, for example, methylchloride and chlorofluoro carbons (Preons).
  • the Freons such as Freon 12 (dichloro-difluoro methane), have become widely used in the industry.
  • the lubricating oil When refrigeration units are assembled, the lubricating oil is hermetically sealed inside the equipment. Here it is in contact with the refrigerant and the metals and other materials of construction during the life of the mechanism. As the totally enclosed units are to provide a satisfactory service for a long period of time, the lubricant should be oxidation stable, non-sludging and non-corrosive. The oil should be suffiicently soluble in liquid Freon to properly lubricate the compressor bearings and other moving parts. In addition, the oil carried over to the low temperature side of the unit should not separate and coat heat exchange surfaces or plug restrictor valves. In the high temperature, high pressure Zone of the unit, the thermal stability of the oil-Freon mixtures in the presence of metal is of great concern. These performance characteristics are the most critical for the refrigerator oil.
  • refrigerator oils can be prepared by extracting mineral lubricating oil distillate to a polyarornatic content less than about 8% by weight, mildly hydrotreating the lubricating oil raflinate to desulfurize the oil and then subjecting the hydrogenated oil to a moderate clay treatment.
  • the drawing is a block flow diagram which sets forth operational steps in the practice of this invention.
  • the starting material is a straight-run mineral oil distiilate, preferably from a parafiinic type crude oil.
  • Paraffinic oils produce lubricating oils of high viscosity index (HVI) which are desired because of the extremes of temperatures at which a refrigerator oil must function in service.
  • HVI high viscosity index
  • the distillates are produced by fractional distillation, generally under vacuum, of the crude oil into fractions of varying viscosity (Saybolt Universal at 100 F.) and boiling ranges, such as 100 distillate, 250 distillate, heavy (700) distillate, and short residue.
  • the distillates are generally refined separately to provide base stocks which can be blended to give an oil of the desired finished properties.
  • the lubricating oil distillate starting material is subjected to an aromatic extraction process with a solvent selective for aromatics, such as furfural, S0 phenol and the like. Extraction is usually conducted at relatively low temperatures of about -200 F. and solvent to feed volumetric ratios of 0.5-5. Polyaromatic content of distillate fractions generally ranges from about 15- 30% by weight. In the process of the invention the extraction should be severe enough to reduce polyaromatic content of the raifinate to less than about 8% by weight, preferably less than 5% by weight, the extraction conditions employed to achieve this depth of extraction depending upon the particular distillate feed and solvent used. Solvent extraction processes are well known and are practiced commercially, therefore detailed discussion should not be required. Acidic solvents such as phenol are preferred as they tend to remove more of the basic nitrogen compounds from the lubricating oil distillates.
  • Extraction removes unstable constituents from the oil, primarily polyaromatics and nitrogen, sulfur, and oxygen compounds, usually in an aromatic structure. Resistance of the oil towards oxidation and sludging is improved. However, the presence of mono-aromatics in the oil is desired to give the oil oxidation stability. By removing polyaromatic and introgen compounds, the extraction improves viscosity index of the oil and improves susceptability of the oil to oxidation inhibitors.
  • dewaxing is required to remove Waxy components, which thereby improves the pour point of the oils.
  • Ra'l'finate from the extraction process can be subjected to any suitable dewaxing operation.
  • Dewaxing processes employed commercially employ solvents such as propane, methyl-ethyl-ketone (MEG/benzene, and the like.
  • Pour point of the dewaxed oil is preferably below about 10 F.
  • dewaxing may precede solvent extraction.
  • the dewaxed rafiinate is subjected to a mild hydrodesulfurization wherein sulfur and oxygen compounds are hydrogenated while the hydrocarbons remain substantially unaffected, i.e. virtually no cracking of the oil or hydrogenation of aromatics present in the oil. Viscosity index of the oil may be slightly increased by the mild hydrotreatrnent.
  • the oil may be in either the gas or the liquid phase during hydrogenation, a very suitabie method being trickle phase hydrogenation wherein the liquid oil is caused to flow through a bed of catalyst in the presence of hydrogen.
  • the hydrogenation is carried out at a temperature of 550 to 700 F a pressure of 450 to 1500 p.s.i.g., a gas discharge rate of 250 1200 standard cubic feet of hydrogen per barrel of oil, and a liquid hourly space velocity of about 1 to 4.
  • a pressure of 450 to 1500 p.s.i.g., a gas discharge rate of 250 1200 standard cubic feet of hydrogen per barrel of oil and a liquid hourly space velocity of about 1 to 4.
  • hydrogen consumption will be about 20-250 standard cubic feet/barrel of oil and sulfur removal will be about 5075% complete.
  • More severe hydrogenation, i.e. loW space velocities, high pressures and high temperatures would increase sulfur and introgen removal, hydrogenation of aromatics, and hydrogen con sumption, but would be considerably more expensive.
  • Suitable hydrodesulfurization catalysts are oxygen or sulfur containing compounds such as the oxides and the sulfides of metals of Group 6 and Group 8 of the Periodic Table. Especially preferred are molybdenum oxide together with cobalt oxide and/or nickel oxide, or tungsten sulfide and nickel sulfide.
  • the catalysts are preferably supported on a carrier such as active carbon, kieselguhr,
  • the catalyst may be used in the form of tablets, pellets, extrudates and the like.
  • I-lydrodesulfurization catalysts are well known and many are available commercially.
  • a suitable hydrogenation method is described, for example by Hoog, US. Patent 2,608,521, issued August 26, 19 52.
  • the oil is moderately treated with a solid adsorbent such as fullers earth and activated clays.
  • a solid adsorbent such as fullers earth and activated clays.
  • Common adsorbents are for example attapulgite and montmorillonite and the acid activated clays such as bentonite, bauxite and alumina.
  • Suitable adsorbents are Porocel and Filtrol.
  • the treatment can be efliected at elevated temperatures, for example, from about 200-500 F.
  • When stripping of hydrodesulfurized oil is employed it is generally desired to pass the stripped oil at normal stripper bottoms temperatures through a percolation filter containing the adsorbent.
  • Contact filtering with moderate clay dosages can be employed if desired.
  • the quantity of adsorbent used generally lies between 0.5 and by weight, preferably between 1 and 5% by weight, calculated on the oil treated. In practice, the various distillate fractions will often be blended in the desired
  • Hydrodesulfurization of the oil results in a more effective adsorbent treatment since sulfur and oxygen compounds are removed in the hydrotreating operation which would otherwise interfere by forming viscous residues on the adsorbent. Moreover, although little or no nitrogen compounds are removed in the hydrodesulfurization, the hydrotreatment apparently promotes nitrogen base formation resulting in increased denitrification in adsorbent treatment.
  • the chloride ion stability test is designed to stimulate conditions in service where oil, Freon and materials of construction are in contact with one another during the operating life of the refrigerator unit.
  • Test oil, Freon 12, steel and copper in prescribed amounts are heated together in a sealed tube at test temperature, generally 400 F. After a given time the tube is cooled and opened and the oil is examined for sludge, color, and the amount of chloride ion formed.
  • a minimum of chloride ion is desirable since chloride accelerates rusting, metal corrosion, and deterioration of organic materials, e.g. insulation.
  • suitable additives such as oxidation inhibitors, anti-foam agents and the like can be incorporated in the treated oil to improve characteristics of the oil.
  • the additives should be oil soluble and non-sludge forming.
  • Oxidation inhibitors such as the phenolic type, e.g. 2,6- ditertiarybutyl-4-methylphenol, are preferred, since nitrogen compounds, such as the amine type, can adversely affect chloride-ion stability of the oil.
  • Viscosity of the final lubricating oil can be within a wide range, depending upon the particular service and preferences of the refrigeration unit manufacturer. Viscosity of lubricating oil in refrigerator service is usually about 500 SSU at 100 F., although oils of a viscosity as low as 80 SSU at 100 F. can be used if desired. Oils having a viscosity of 1000 SSU at 100 F. and higher are desired for air conditioning units. Viscosity index of the final oils is at least about 85 and preferably at least 90.
  • the polyaromatic content was about 2.5% wt.
  • the various blends were subjected to clay contacting or percolation with or without a previous hydrotreatment over nickel molybdenum on alumina hydrogenation catalyst. Nitrogen content and chloride ion test results are given below in Table II. The chloride ion test was determined on sample containing 0.5% w. oxidation inhibitor (2,6-ditertiarybutyl-4-methylphenol) and 5 p.p.m.
  • a process for the production of refrigerator oil which comprises extracting a paraflinic lubricating oil distillate with a solvent selective for aromatics to obtain a ratfinate having a polyar-omatic content less than about 8% by weight, dewaxing the raffinate, catalytically hydrotreating the dewaxed raflinate under mild conditions of about 550 to 700 F., about 450 to 1500 p. s.'i.g., and about 1 to 4 liquid hourly space velocity, and contacting the hydrotreated oil with a solid adsorbent.
