Extractive distillation (ED) uses a solvent in distillation applications to enhance separation efficiency. Throughout the academic world, this method is recognized as an effective way to separate close-boiling mixtures. Recently, ED has gained widespread acceptance among industrial users. In particular, ED technology can be applied to three important commercial applications to improve profitability of the petrochemical and refining industries. These include: Benzene, toluene and xylene (BTX) recovery and purification from aromatics-containing feedstocks Styrene recovery from pyrolysis gasoline Sulfur removal from cracked gasoline stock.
