Abstract:
A major challenge for industrial operators and EPC firms is to optimize capital and operational costs of their new and existing facilities. Computational Fluid Dynamics (CFD), even though a powerful and comprehensive modeling tool, is not widely used in molecular sieve industry. This paper will focus on CFD models developed by CECA (Arkema) and their applications to optimize the adsorption and regeneration phases. The first part will discuss ways to optimize the molecular sieve bed designs through insight on bed configuration, hydrodynamics and other process parameters. The second part will address the troubleshooting issues, optimizing and adapting the plant operation under different constraints. The two parts, that are key to cost savings, will be illustrated using real industrial cases.
