Étude et Vérification des paramètres opératoires du réacteur régénérateur de l’unité RFCC de la Raffinerie d’Alger.

Abstract

One of the most important refining operations of modern refineries; FCC (Fluid Catalytic Cracking) is a conversion technique used in refineries to produce light petroleum products such as LPG fromheavyoil fractions, gasoline, diesel and fuel oil. The objective is to ensure an efficient conversion process in the presence of a catalyst, the residue from the ADU(Unite100) unit into petroleum products (hydrocarbons) high quality, while minimizing operating costs and meeting environmental emission standards. In view of ourwork (optimization of the FCC process) we have detailed the catalytic cracking process and studied the performance (activity, selectivity, stability) of the catalyst uses as well as the influence of the operating variables on the quantity and quality of the yield by monitoring the main operating parameters(available) of the reactor-regenerator section. This includes the simulation of the reactor-regenerator cut by the HYSYS ASPEN V14 software for confirmation of the obtainedresults and the correct operation of the operating parameters of the unit that performance depends on it.
