Experimental study of some parameters on the quality of the base oil Manufactured in the reclaim units

Abstract

Difference in color is a major source of distinction between the lubricants extracted directly from the lubecuts and those manufactured in the reclaim units.The mentioned difference can be regarded as one of the main problesm for these products.In order to imporve the color quality of final product, possible modifications  in the reclamation method have been investigated. Th effort has been described in this paper. Acid wash, followed by neutralization and a final  discoloration  using  surface active agents such as bentonite,is the method which has been used,and depending on the quality of what has been done,the level of clearness of the product could therefore vary between 2 to 4.5 on the LOVIBOND scale.
In this research, different processes in production line has been investigated and the dominant parameters on the product quality, has been indentified. Among these, the factors which have the maximum effectiveness on the samples, have been chosen. Temperature variation in the distillation tower, the amount of acid used, the acid wash temperature, the amount of surface active agents, the discoloration temperature and temperature required for discoloring reservoirs, were among the studied parameters. In order to make sure about the quality of the obtained product, the physical and chemical properties of the product have been taken under the precise consideration. Viscosity index, flash point, and fall-out point are among the properties which have been studied
