Title
Studies in adsorptive and Reactive Separations
Abstract Adsorptive techniques are becoming important when the mixture is complex to separate by conventional methods like distillation. This work is divided into two case studies; first one is “synthesis of carboxylic esters using reactive chromatography” and the other is “separation of hydrogen isotopes using palladium adsorbents”. The integration of a reaction and chromatographic separation into a single unit is called as reactive chromatography (RC). Application of RC for synthesis of esters through esterification of acetic acid with corresponding alcohols using ion exchange resin Amberlyst-15 has been studied. This study includes feasibility test kinetics data estimation model validation using simulated moving bed reactor (SMBR) experimental results optimization of operating conditions and operating cost comparison for the two multifunctional reactors i.e. reactive distillation and chromatographic reactor. Feasibility of hydrogen isotope separation through different chromatographic methods is explored. Palladium is found to have highest separation factor for hydrogen isotopes at ambient temperature is selected as adsorbent. Simulators for chromatographic techniques are developed and are validated using chromatographic experimental results. To recover high purity deuterium in continuous mode a six column simulated moving bed chromatographic (SMBC) set-up is proposed based on experimentally validated simulator.
