Description
Summary:Increasing emphasis on process intensification for enhancing industrial chemical processes opens up many promising opportunities for an integrated rather than sequential (the onion-model approach) process synthesis and design. The present article introduces the concept of solid catalyzed reactive HiGee stripper (SCRHS) where reaction and stripping are integrated in a solid catalytic rotating packed bed. SCRHS is modeled for an esterification reaction, and analyzed in detail. Rotation of reactive stripper offers several advantages such as faster mass-transfer and higher product concentration over conventional reactors. Intraparticle diffusion-based modeling, component-based effectiveness factor, and instantaneous selectivity provide several insights into the proposed integrated process. Obtained results are encouraging and show that SCRHS is a promising candidate for future esterification plants. ► Concept of solid catalyzed reactive HiGee stripper (SCRHS) is introduced. ► Interdependent esterification and etherification reaction system is analyzed. ► Modeling, simulation and parametric analysis of SCRHS is performed. ► Catalyst modeling and component-based effectiveness factor are included. ► Better mass transfer and conversion are achieved in SCRHS over conventional reactors.
