The production of gas from fields yielding large amounts of hydrogen sulfide has created an acute need for reliable protection of gas production and transmission equipment against corrosion and corrosive-mechanical wear. In this connection it has become necessary to develop lubricating oils that maintain a high level of tribotechnical and protective properties when operating in contact with corrosive media that contain hydrogen sulfide. Gas pumping units of the centrifugal type are commonly lubricated with turbine oils Tp-22 and Tp-22s, which contain additive packages. The antiwear and anticorrosion properties of these oils are inadequate in this sort of service, where they are repeatedly saturated with corrosive impurities, primarily hydrogen sulfide. The work reported here was aimed at selecting effective combinations of additives to improve the lubricity and anticorrosion properties of oils operating in the presence of hydrogen sulfide and an electrolyte, containing all components in optimal ratios.
