Tratamiento de aceite dieléctrico residual en la Empresa Biolubricantes S.A.S, empleando tierras de blanqueo y Mejorador de Índice De Viscosidad (MIV), para su aplicación como base lubricante en motores de bajo rendimiento.

Abstract

The aim of this work is to improve the physicochemical properties (color, viscosity, density) of the residual dielectric oil in the company Biolubricantes S.A.S, using bleaching earths and a viscosity index improver (MIV). For this purpose, an oil regeneration stage was carried out using a factorial design 23 central rotary compound + central points with replica, evaluating the effect of the earth ratio: oil, activation temperature and contact time, measuring color and density. For the second stage of viscosity index improvement (MIV), the second factorial design 23 was made measuring the viscosity of the dielectric oil regenerated from stage 1 and evaluating the effect of the MIV ratio: oil, homogenization temperature and homogenization time. The experimental results showed that all the studied variables have a significant effect on the color, density and viscosity. For stage 1 the best conditions of color and density (2.5; 0.8621g/mL) correspond to conditions of: earth:oil ratio 11.7 m:v, activation temperature 68.13ºC and contact time 70 min. Regarding the stage 2 the desired viscosity corresponds to (161 cSt) following the SAE standards, to the following conditions: MIV:oil ratio 3,75 m:v, homogenization temperature 80ºC and homogenization time 180 min. From the obtained conditions it was possible to have a lubricant base with improved properties for the company Biolubricantes S.A.S.
