Purification of Compressor Oil in Cooling Units

Cooling machines, industrial purification systems and units are widely used in industry for artificial decrease and subsequent maintenance of low temperature in a given facility. Herewith, the problem of compressing and transferring the coolant vapors is solved by special compressors.

The main consumable material of such equipment is compressor oil that lubricates the main parts, couplings and assemblies, as well as provides protection against corrosion.

Compressor oil of cooling units has to meet special requirements, which are provided due to the contact of the lubricant with the coolant, as well as changes in temperature and pressure. Such oil should have a sufficient chemical stability and a low pour point. The lubricating fluid of cooling equipment must be free of water-soluble acids and alkali, mechanical impurities, and water. The acceptable acid number depends on the oil brand, and should not exceed 0.02-0.05 mg KOH/g.

Compressor oil of cooling machines works under the conditions of high temperatures (120-230ºС) and high pressures (up to 22.5 MPa). These factors lead to an intense oxidation and formation of large amounts of organic compounds. In the high-pressure compressor oil an intense condensation of water vapors contained in the compressed air takes place, some of which get into oil.

Analysis of the quantitative composition of contaminants present in waste compressor oil shows that among the undesirable impurities dominate solids, asphaltenes, carbenes, inorganic contaminants and water. As previously noted, the presence of such substances is considered to be unacceptable, therefore it is necessary to purify compressor oil.

GlobeCore offers to companies and enterprises, which have cooling equipment of various capacities on their balance sheet, units for purification of compressor oil.

With the oil purification unit you can achieve the following targets:

  • reduce the content of dissolved and undissolved water in oil from 100 g/t to 10 g/t for one cycle;
  • reduce the gas content from 10-12% (by volume) to 0.1%;
  • remove mechanical impurities larger than 5 microns.

Timely cleaning of compressor oil in refrigeration systems increases the reliability of the work of compressor equipment, reduces downtime, and saves money on the purchase of fresh lubricating fluids.

Exposure to vacuum provides for a high-quality procession of compressor oil and leaves all useful hydrocarbons in it. This results in an extended service life of the lubricating fluid. The principle of operation of the unit is as follows: at first, oil is pumped in through a filter with a fineness of 25 microns, whereupon it is delivered to the heater. From the heater oil gets into the vacuum column, where there is a nozzle at which water and dissolved gases are boiled away. Once this is done, oil is pumped out through a filter with a capacity of 5 microns (upon the Customer’s request it is possible to install a filter fineness of 1 micron).

GlobeCore manufactures units for purification of compressor oil on the large-scale production, as well as according to your specific needs. Mass production models can be purchased directly from the warehouse. In the case of an individual order the unit will be manufactured within 45 working days.

Putting a unit into operation lasts only a few days. During the time that it takes you to carry out preparation works, the GlobeCore equipment can be delivered to any place in the world.

If necessary, our experts will commission and adjust the unit for purification of compressor oil, as well as train the staff of your Company.
