Treatment and Recycling of Used Lubricating Oil

This research is about the recycling of used lubricating oil. Two different types of lubricating oil which were ACCEL ULTRA and MACH5 which were used as engine oil were covered by the study.Physical testing was conducted on the two samples before and after the treatment in order to compare the result of analysis. Two different kinds of solvents were used in the treatment of the used oil which started by filtering the oil then extracting the oil by solvent extraction technique at 70C?. Followed by distilling the oil at 140C? -170C? In order to separate the solvent from the oil so as to be used again. At this stage the oil was ready for testing. The tests included: kinematics viscosity at 40C ? and 100C?, viscosity index, specific gravity, flash point, insoluble matter, water content and total base number. This results obtained revealed that treatment has improved and enhanced the physical properties of the used lubricating oils, the comparison between treated and untreated data revealed appositive impact associated with viscosity at 100C? for oil.for Mach5, Accel Ultra the viscosity before treatment was 18.3, 16.9 and 15.03 while the viscosity after treatment was 15.03, 19 and 17.2 respectively.The recommendation of the study is to demark certain areas for collection and recycling of oil.
