Project Report on Lube Oil Blending And Greases Plant

Lube   oils   generally  include all   classes   of   lubricating materials  that are applied as fuels.  Nearly all of the  world's lube oils are made from the move viscous portion of the crude oil which  remain after removal of gas oil and lighter  fractions  by distillation.  Much of the variations in physical characteristics and  performance  qualities  of lubricating  oils  prepared  from different  crude sources can be accounted for by the millions  of variations that can exist in a single large hydrocarbon molecule.  In order to minimize variations and produce products that provide consistent  performance in specific applications, four steps  are followed in the manufacture of finished lubricating oils from the various  available crudes.  Selection and aggregating  of  crudes according   to  the  principal  types of  hydrocarbon present; distillation   of  the  crude  to  separate  it  into   fractions containing   hydrocarbons  in the same sp  range;  processing  to remove undesirable  constituents from the various fractions or to convert  same  of these materials constituents from  the  various fractions or to convert same of these materials to more desirable materials,  and blending to attain the  physical  characteristics that  are  required in the finished  products  and  incorporating chemical  agents to improve performance. Naphthenic  oil is  more preferable  then paraffinic  oil because of its fluidity  at  low temperature,   particularly  in  cold  weather.  Paraffins   have relatively  low viscosity,  density  and high  freezing point  as compared to other types,  they  are  used more commonly.
