Edeleanu process

The Edeleanu process is a type of extraction process in the petroleum refining industry, whereby liquid sulfur dioxide is used to extract aromatics from kerosene pool, liquid SO₂ selectively dissolves the aromatics leaving behind the low aromatic content kerosene as the finished product.^[1] It is named after the Romanian chemist of Jewish origin Lazăr Edeleanu. The aromatic extract is then separated from SO₂ through rectification and SO₂ recirculation. Temperature is maintained at -20°C.^[2]

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.
