View source for Edeleanu process

The '''Edeleanu process''' is a type of [[extraction (chemistry)|extraction]] process in the petroleum [[refining]] industry, whereby liquid [[sulfur dioxide]] is used to extract [[aromatic]]s from [[kerosene]]. Liquid SO<sub>2</sub> selectively dissolves the aromatics leaving behind the low aromatic content kerosene as the finished product.<ref>{{Cite Merriam-Webster|Edeleanu process|accessdate=2019-07-11}}</ref> It is named after the [[Romania]]n chemist [[Lazăr Edeleanu]]. The aromatic extract is then separated from SO<sub>2</sub> through [[Distillation#Fractional_distillation|rectification]] and SO<sub>2</sub> recirculation. Temperature is maintained at -20°C.<ref>Robert L.

By using a blend of sulfur dioxide and [[benzene]], some improvement can be effected, more suitable solvents such as [[furfural]], [[phenol]] and N-methyl-2-pyrrolidone are used.
