Evaluating Commercial Macroporous Resin (D201) for Uranium Uptake in Static and Dynamic Fixed Bed Ion Exchange Column
As part of the development of equipment and innovative technology for the process flow-sheet, a study on the selection of good resin for uranium uptake is ongoing. Both static and dynamic column equilibrium testing upon synthetic and Gattar pregnant leach solutions (PLS) were carried out to estimate the change of total capacity and breakthrough capacity of the commercial macroporous anion excha...
متن کاملPredictions of Protein Adsorption and Desorption in Liquid-Solid Circulating Fluidized Bed Ion Exchange System
The interest in recovery of various functional proteins from large volume of industrial broths and biological wastewater streams has increased in recent years, due to the advancement in genetic engineering, and concerns about recycling limited resources and environmental protection (Lan, 2001). Ion exchange adsorption and chromatography have long been used for downstream processing in the biote...
متن کاملA Study of Ion-Exchange Chromatography in an Expanded Bed for Bovine Albumin Recovery
In the present work, the effect of bed expansion on BSA adsorption on Amberlite IRA 410 ion-exchange resin was studied. The hydrodynamic behavior of an expanded bed adsorption column on effects of the biomolecules and salt addition and temperature were studied to optimize the conditions for BSA recovery on ion-exchange resin. Residence time distribution showed that HEPT, axial dispersion and th...
متن کاملOptimization of azeotropic protein separations in gradient and isocratic ion-exchange simulated moving bed chromatography.
The separation of dilute binary mixtures of proteins by salt aided ion-exchange simulated moving bed (SMB) chromatography is optimized with respect to throughput, desorbent consumption and salt consumption. The optimal flow-rate ratios are analytically determined via an adopted "triangle theory". Azeotropic phenomena are included in this procedure. The salt concentrations in the feed and recycl...
متن کاملMathematical modeling of salt-gradient ion-exchange simulated moving bed chromatography for protein separations.
The salt-gradient operation mode used in ion-exchange simulated moving bed chromatography (SMBC) can improve the efficiency of protein separations. A detailed model that takes into account any kind of adsorption/ion-exchange equilibrium, salt gradient, size exclusion, mass transfer resistance, and port periodic switching mechanism, was developed to simulate the complex dynamics. The model predi...
