In the fluid catalytic cracking (FCC) process, the riser is the most important equipment where the reaction taken place. In the riser operation, the feedstock is fed through injectors and mixed with catalyst and steam. A good design and localization

The objective of this work is the mathematical formulation of a prilling tower taking into account the solidification of the urea droplets, calculated by a shrinking unsolidified core model. The multiphase gas- liquid flow was modelled using the Eule

Despite being simple equipment with wide range of operation, low investment cost and maintenance, the cyclones present a complex turbulent flow, with recirculation zones, high-intensity turbulent, high vorticity conservation, among others. The mathem

Most studies neglect the presence of thermal cracking reactions in industrial FCC process. Nevertheless, the present work proposes a new model which modified the 10-lumps kinetic model given by Jacob el al. (1976), through to inclusion a new lump nam
