SEPARATION OF METAL ELEMENTS FROM USED ENGINE OIL BY USING CERAMIC MEMBRANE TECHNOLOGYMUHAMMAD HATTA DAHLAN
The engine oil use nowadays has been increasing due to high quantity of vehicle use. The more the engine oil was used, the more waste of used oil in environment. After periodic use, the characteristic of used-engine oil would be different in composition and colour. Used engine oil contained the metals namely aluminium (Al), iron (Fe), copper (Cu), zinc (Zn) and the other metals element. Ceramic membrane technology would be used in this research to separate the metal elements from used engine oil. This study would focus to analyze the metals element separation process from used engine oil and to investigate the used engine oil characteristic after refinement. In this study, membrane ceramic that used were compounds with clay, zeolite and iron. The result of this research were calculated by flux equation, coefficient of rejection, and flashpoint of waste of used oil. The result showed that ceramic membrane that compound with 30% zeolit, 5% iron powder and 65% clay at flowrate 3l/min were resulted in Al 0.12 ppm, 0.12 ppm Fe, Cu 0.003 ppm and Zn 0.07 ppm in flux analysis. The temperature flashpoint of used oil slightly the same with the temperature flash point of oil standard.
