Oil recovery method for displacement rotary air compressor |
| abstract |
The turbine oil used in a screw-type air compressor as a lubricant and sealant is mixed with approximately 40 percent trichlorofluoromethane, trichlorotrifluoroethane, or dichlorotetrafluoroethane to raise the specific gravity of the mixture above that of water. When the compressed air discharged from the compressor is cooled, moisture condenses and the entrained droplets of the oil mixture are precipitated and settle under the aqueous condensate so that the latter may be removed by overflow while the oil mixture may be returned to the compressor. |
