Abstract:
The operating strategy so-called PR-PCO-NFZIII of the three-zone simulated moving bed (SMB), aiming for decreasing the desorbent consumption and the number of pumps for the separation of glucose and fructose, was proposed. Its principle was based on the port-relocation (PR) and port-closing/opening (PCO) techniques with no flow in zone III (NFZIII) during the later period of switching tine. In this strategy, the raffinate and extract products were alternately collected. The adsorption model and its parameters were determined from the breakthrough curve experiments in a single chromatographic column. This adsorption model was incorporated into the SMB model and was verified with the experiments in the three-zone simulated moving bed operational mode (TZ-SMB). Then the SMB model was used for the simulation of PR-PCO-NFZIII. The calculated performance parameters of the TZ-SMB, port-relocation, and PR-PCO-NFZIII were compared. Results revealed that PR-PCO-NFZIII outperformed the TZ-SMB mode in terms of solvent consumption, reduced number of pumps (only solvent and feed pumps were employed), and lower pressure drop. The desorbent flow rate was reduced by approximately 25% when compared with TZ-SMB mode. Furthermore, this strategy offered high product purity (> 98%), high productivity and %recovery as those obtained from the TZ-SMB. With this approach, the purities and productivities of both products were not compromised. The product concentrations were adjustable as a function of extract collecting time to suit the specific demand. Furthermore, with the suitable choice of partial collecting/discarding strategy, the concentration of extract and raffinate products can be further improved.
