Definitions

  • This invention relates to a process for the continuous manufacture of a lubricating grease and in particular of a base grease which serves as a basis for the manufacture of a wide variety of lubricating grease formulations containing one or more additives.
  • the present invention relates to a process for the continuous manufacture of a lubricating grease comprising blending feed materials and lubricating oil and pumping the resulting blend through at least one motionless mixer which is heated to such a temperature that soap formation takes place and a resultant grease is formed.
  • Suitable feed materials are the usual thickening or gelling agents which in the case of soaps are often made in situ in at least part of the lubricating oil from saponifiable material, saponification agents and optionally complexing agents.
  • Suitable saponifiable materials are long chain fatty esters, especially glycerides, in particular where the fatty group contains a hydroxy radical, such as ricinoleyl (castor oil) or hydrogenated ricinoleyl (hydrogenated castor oil).
  • Another method of soap formation is to neutralize fatty acids or hydroxy fatty acids in mineral oil with alkali metal or alkaline earth metal hydroxides (or mixtures of both) or hydrates thereof - in particular lithium hydroxide monohydrate (LiOH.H 2 0).
  • alkali metal or alkaline earth metal hydroxides or mixtures of both
  • hydrates thereof in particular lithium hydroxide monohydrate (LiOH.H 2 0).
  • hydrogenated fatty acids or hydrogenated hydroxy fatty acids are commonly used in the neutralization.
  • Suitable saponification agents are alkali metal or alkaline earth metal hydroxides (or mixtures of both), in particular lithium hydroxide, or hydrates thereof. Therefore, the feed materials preferably comprise
  • Suitable complexing agents are short chain fatty acids, such as acetic acid, dicarboxylic acids, such as azelaic acid, hydroxy aromatic acids such as salicyclic acid, boric acid, aluminium compounds, etc. If such complexing agents are used the proportion of saponification agents is usually increased with about the stoichiometric quantity of the complexing agent.
  • thickening agents are clays, including coated clays, silica gels, polymers, polyureas, carbon black, dyes, etc.
  • Suitable lubricating oils are mineral oils, including hydrogenated mineral oils, synthetic oils, such as ester oils, polyolefin oils, silicon oils, phosphate esters, polyphenyl ethers, etc.
  • Suitable mineral lubricating oils include HVI, paraffinic MVI, naphthenic MVI and LVI oils.
  • lubricating oil and additives such as antioxidants, antirust, anti-wear and extreme pressure agents, pour point depressants, metal deactivators etc.
  • Suitable laboratory-type motionless or static mixers have the form of a cylinder or tube having a length of 65.5 to 66.5 cm and a diameter of 3.3 to 3.6 cm. They are provided with an insulated heating jacket, using e.g. electric tape having a heating capacity of e.g. 400 watt per mixer, or a heating medium as the heating source.
  • the inside of the cylinder is provided with e.g. corrugated plates, perforated plates, intermeshing and intersecting bars and similar fixed mechanical obstacles causing mixing and heat exchange.
  • a suitable motionless mixer containing perforated plates is described in e.g. GB-A-2086249, but other types may be used as well.
  • Suitable mixers are: the Sulzer motionless mixer SMX type which is 655 mm long x 36 mm internal diameter and the Sulzer motionless heat exchanger SMXL type which is 665 mm long x 32.8 mm internal diameter.
  • the base grease-making ingredients are preferably blended at room temperature in a container from which they are pumped through at least one motionless mixer, preferably several motionless mixers, preferably longitudinally connected. They may also be, or additionally be, connected in a parallel manner.
  • the average velocity of the mixture in the mixers may be 3 kg to 50 kg/h, preferably 7 to 30 kg/h, the flow preferably being laminar.
  • the pressure at the entrance of the first mixer may be between 1 and 30 bar, preferably between 1 and 15 bar.
  • the mixers are heated to a suitable high temperature, e.g. at least 120°C, preferably between 120 and 250°C, preferably up to a maximum temperature between 180 and 230°C, so that a grease structure is formed on cooling.
  • a suitable high temperature e.g. at least 120°C, preferably between 120 and 250°C, preferably up to a maximum temperature between 180 and 230°C, so that a grease structure is formed on cooling.
  • a suitable high temperature e.g. at least 120°C, preferably between 120 and 250°C, preferably up to a maximum temperature between 180 and 230°C, so that a grease structure is formed on cooling.
  • a suitable high temperature e.g. at least 120°C, preferably between 120 and 250°C, preferably up to a maximum temperature between 180 and 230°C
  • Thermocouples may be placed between the mixers for temperature control.
  • part of the finished grease may be recycled.
  • the pump at the entrance of the first mixer may be provided with a recycling circuit.
  • the subsequent removal of water can be accomplished by simply dumping the resulting grease in an open vessel, whereafter any further lubricating oil and any desired additives can be added.
  • the base grease together with additional lubricating oil and additives is pumped through a heat exchanger tube for mixing and cooling to obtain the desired consistency.
  • Homogenisation of the grease if necessary, is carried out using e.g. a Manton Gaulin homogeniser at 3000 psig (20.7 MPa), a mill or a rolling device etc.
  • the finished grease is obtained at the outlet and cooled in a jacketed SULZER MONOTUBE HEAT EXCHANGER which consists of 2 units each 1540 mm long x 32.8 mm internal diameter. Each unit contains 1 SMXL type heat exchanger.
  • the unworked/worked penetration at 25°C was 262/273 dmm (ASTM D217-82). (1 dmm corresponds with 0.1 mm) and the dropping point was 197°C. (Worked penetration is the penetration at 25°C after 60 double strokes in a standard grease worker).
  • the first two Sulzer mixers were of the type SMX DN32, having a length of 655 mm and an internal diameter of 36 mm and the last two were of the type SMXL DN32 (heat exchanger type for boosting the heat transfer during warming up of the viscous mixture), having a length of 665 mm and an internal diameter of 32.8 mm.
  • Examples 2-6 are carried out in the arrangement of Example 1, but the flow rate is changed, resulting in different outlet temperatures, penetrations and dropping points (see Table A).
