Computational fluid dynamics modelling of multiphase reactors

Computational Fluid Dynamics (CFD), originally developed for non-reacting systems and successfully applied to aerodynamic design, has been recently proposed also for process engineering, in particular for multiphase reactor simulation. In fact CFD modelling can significantly contribute to better understand the fluid dynamics of process equipment, especially when their performances have to be scaled up from a laboratory or pilot plant scale to an industrial size. In this paper two different applications of this modelling approach to multiphase reactors are presented: in the first one slurry bubble columns are considered, while the second one is related to a lab-scale stirred tank reactor (CSTR) simulation.

Simulation of blowout events: Integration of different modelling approaches within industrial risk assessment and management tools

One of the most critical incidental events associated both to the exploration and exploitation of hydrocarbon fields is the uncontrolled well blowout. In particular, during blowout of onshore wells, the associated oil and gas dispersion in the atmosphere and land requires the quikly definition of a contingency plan aimed to reduce damages. To this aim, the Agip Division of Eni has undertaken a specific R&D project, with the technical and scientific support of EniTecnologie, TEA and TEMARS companies.
