On the transition to the use of modern lubricants in systems of energy facilities

The analysis of turbine oils currently in use is given. The classifications for petroleum base oils according to the systems developed at JSC VNIINP and the American Petroleum Institute are presented. The transition from the operation of turbine oils of the first group to more advanced oils obtained on the basis of base oils of the second group and above is justified. The problems that may arise when replacing oils of the first group with modern oils in connection with the processes of mixing energy oils of various formulations are outlined. The mixing process is complicated by the compatibility factors of both the commercial products themselves and the additive compositions used, as well as possible contamination with oil sludge of lubricants in operation and possible contamination with water and mechanical impurities of the new energy oil at the delivery stage. The necessity of analyzing the possibility of mixing is explained both by the compatibility of the energy oils being tested and by the compatibility of the additive package used in them. A list of indicators is presented by which it is possible to judge the possible compatibility of the energy oils under consideration. The results of the compatibility analysis are presented. In modern foreign policy conditions, for the Russian Federation, there is a need to activate Russian developments and provide modern lubricants for a new generation of energy facilities. A possible solution to this issue, developed by the specialists of the NRU MPEI, is presented. A system for the production of oil distillate with subsequent production of base (group III) and commercial oil for high-ash initial coals of the brown coal and early black coal stages of coalification of coal basins closed for development is presented.
