Chromatographic Separation and Determination of Functional Additives in Turbine Oil

Abstract

A procedure is proposed for the simultaneous determination of functional additives (ionol, V 15/41, D-157) in turbine oil, including two-stage solid-phase extraction and the analysis of the extract by reversed-phase HPLC. The procedure for the simultaneous determination of functional additives was tested in the analysis of an industrial sample of used TP-22 S turbine oil. Monitoring of additive concentrations in the operation of compressor stations enables the timely control of the dynamics of turbine oil degradation over the period of its use and proper recommendations on the intervals for its replacement in the system.
