چکیده
In this study, separation of para-xylene (PX) from C8 isomers by adsorption on a completely potassiumexchanged Y zeolite in a simulated moving bed (SMB) in industrial scale is modelled and simulated. In the model,adsorption isotherm is Langmuir type and in mathematical model, axial dispersion and linear driving force for masstransfer were considered. Aspen chromatography software was used for mathematical solution of differential equations.Optimization in the simulation leads to find the operating condition of the SMB such as beds switching time andrecycle flow in order to get high purity and recovery of p-xylene. The obtained results of simulation were verified withan operational plant data. The purity and recovery of about 99.7 % and 96% were obtained that were in agreement withthe plant data.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
