Base and commercial oils. Factors in improving the quality

Technology for Producing M10dm Oil Based on Oil Distillates Ferghana Oil Processing Plant (Fopp)

“…Analysis of the components of base oils obtained by selective purification with phenol at the fnpz revealed a significant difference in their properties, which often do not meet the criteria of international standards, according to which the carbon content in aromatic rings should not exceed 7%. In addition, base oils obtained from high-sulfur raw materials of unstable chemical composition often contain an understated number of high-index components and a lot of resins (up to 3.1 %) [1]. As a result, in order to obtain motor oil of the M-10 DM brand corresponding to GOST, it is necessary to select different fractions of oil distillate obtained during complex processing, including vacuum distillation, selective purification with phenol, dewaxing and Hydrotreating.…”

“…Severe operating conditions of high-powered diesel engines, which are widely distributed in the territory of the Republic of Uzbekistan, impose increased requirements for the quality of engine oil. Oils intended for these purposes must have, first of all, high thermal-oxidative stability, an increased stock of washing-dispersing and anti-carbon properties, as well as long-term anti-wear, anti-corrosion and anti-pressure qualities [1].…”
