COSMO-based/Aspen Plus process simulation of the aromatic extraction from pyrolysis gasoline using the {[4empy][NTf2] + [emim] [DCA]} ionic liquid mixture

Abstract

Empleo de los programas de simulación COSMO y Aspen Plus para el estudio del proceso de extracción de hidrocarburos aromáticos de las gasolinas de pirólisis empleando una combinación binaria de dos líquidos iónicos: 1-ethyl-4-methylpyridinium bis(trifluoromethylsulfonyl)imide ([4empy][NTf2]) y 1-ethyl-3-methylimidazolium dicyanamide ([emim][DCA]).In this paper, a computer-aided methodology combining COSMO-based molecular simulations and Aspen Plus process simulations has been used to study the extraction process of aromatic hydrocarbons from pyrolysis gasoline employing a binary mixture of 1-ethyl-4-methylpyridinium bis(trifluoromethylsulfonyl)imide ([4empy][NTf2]) and the 1-ethyl-3-methylimidazolium dicyanamide ([emim][DCA]) ILs as solvent.
