TY - JOUR AU - Surovskaya, G. AB - V. V. Grigor'ev and G. V. Surovskaya UDC 621.899:621.892.098 In recent years, more and more attention has been given to problems in reclaiming used lubricants. One of the best fire-resistant synthetic products is the oil OMTI, based on trixylenyl phosphate (Specification TU 6-25-12--75), which is used in the lubrication and con- trol systems of power plant turbogenerators. The demand for this oil is increasing steadily, and hence it has become necessary to develop reclaiming methods. For our studies we took a sample of used OMTI oil -- an emulsion with a dirty yellow color that did not meet the specification requirements for optical density, acid number, content of xylenols~ and other property indexes (Table i). The changes in oil properties during service are due to contamination with water, aging, and the accumulation of wear products. Two fil- trations of the used oil through paperboard improved the color, removed the moisture, and cut the xylenol content approximately in half. Additional filtrations did not give any further improvement in the oil quality; and the oil, as before, did not meet the requirements for the commercial product. The filtered OMTI oil samples were finished by treatment with adsorbents (bleaching clays, metal oxides, TI - Reclaiming used fire-resistant turbine oils JF - Chemistry and Technology of Fuels and Oils DO - 10.1007/BF00725779 DA - 2004-11-18 UR - https://www.deepdyve.com/lp/springer-journals/reclaiming-used-fire-resistant-turbine-oils-rVXOEmJ6QX SP - 321 EP - 322 VL - 23 IS - 7 DP - DeepDyve ER -
