EXTRACTION OF AROMATICS FROM HEAVY NAPHTHA USING DIFFERENT SOLVENTS

Abstract
Aromatic hydrocarbons are very important to the petrochemical
industry. Among these are benzene, toluene and xylene (BTX), which are
basic raw materials for the production of a number of important
petrochemicals. There are many processes used to separate aromatic from non
aromatic such as fractionation, azeotropic distillation and liquid / liquid
extraction, etc. Liquid – liquid extraction is unique, efficiently used for heat
sensitive, close boiling components and for separation of components not
possible by other unit operations and it could be done at ambient temperature
makes it more energy efficient.
