TWIN-SCREW COMPRESSOR PERFORMANCE AND COMPLEX ESTER LUBRICANTS WITH HCFC22.

Author(s) : SJOHOLM L. I., SHORT G. D.

Summary

THE NEW APPLICATIONS CALL FOR NEW DEMANDS OF SUITABLE SCREW COMPRESSOR LUBRICANTS, MAINLY DUE TO: REQUIREMENTS FOR SMALL OIL SEPARATORS ; SHORT DWELL TIME IN OIL SUMP ; GOOD OIL RETURN CHARACTERISTICS ; NO OR LIMITED EXTERNAL OIL COOLING ; AND HIGH DISCHARGE TEMPERATURE. THE USE OF MINERAL LUBRICANTS IS LIMITED BECAUSE OF HIGH VISCOSITY REQUIREMENTS. THE USE OF POLYALPHAOLEFINS (PAOS), IS LIMITED BECAUSE OF POTENTIAL PHASE SEPARATION. THE COMPLEX ESTER LUBRICANT FAMILY IS DISCUSSED. SCREW COMPRESSOR PERFORMANCE, BASED ON GAS RIG TESTS, IS COMPARED FOR R22-PAO AND R22 COMPLEX ESTER.
