PGO Processing with azeotropic rectification to extract naphthalene

Abstract

In this study, azeotropic rectification method was attempted to extract industrial naphthalene from fractions of liquid pyrolysis’ products of the hydrocarbon feed and obtain refined naphthalene. Extraction of naphthalene from fractions of liquid pyrolysis products (LPP) from hydrocarbons including the atmospheric and then the vacuum distillation of heavier cut with the extraction of naphthalene concentrate that is having azeotropic rectification and then it is coming for the stages of crystallization and pressing. In order to obtain condition for industry naphthalene purification using azeotropic rectification method, the Belarussian heavier cut’s chromatography were studied. The optimization of the process of azeotropic rectification to obtain refined naphthalene is mainly discussed to provide a theoretical for the actual production and technology improvement
