Refining of vacuum gas oil using a mixed solvent

Auther : M. A. FAHIM

Department of Chemical Engineering, University of Kuwait

 

ABSTRACT

 

A mixed solvent composed of ethylene glycol and N-methyl-2-pyrrilidone was used to extract heavy vacuum gas oil distillate (VGO) to produce lube oil base stock. The solvent capacity and selectivity were studied in terms of its composition. An optimum solvent composition of 10-15% ethylene glycol and 90-45% N-methyl-2-pyrrilidone gave base stock yield of 66-70% at operating conditions favourable for industrial applications.
