“…Simulated moving bed (SMB) is an efficient technology for the large-scale production of high-purity HMF, allowing continuous chromatographic separation. 27,28 In this study, we develop an economically efficient process for producing FDCA from glucose, a sustainable biomass material. The proposed system integrates the conversion of glucose to HMF and the subsequent upgrading of HMF to FDCA.…”

The transition from fossil fuels to biomass as a source of polymeric materials is regarded as a sustainable approach. 2,5-Furandicarboxylic acid (FDCA) is an alternative to terephthalic acid (TPA), a petrochemical monomer used to produce polyethylene terephthalate (PET). Polycondensation of FDCA yields polyethylene furan-2,5-dicarboxylate (PEF), which exhibits superior properties to PET. In this study, an integrated process was developed for converting biomass-derived glucose into FDCA. Heat integration through pinch analysis was employed to minimize energy consumption. The minimum selling price (MSP) was calculated based on discounted cash flow analysis. The MSP of FDCA was estimated to be $1064/tonne, which is cost-competitive compared to the most recent (June 2023) production cost of TPA, with an MSP of $1110/tonne. Life-cycle assessment was used to estimate the environmental impacts associated with FDCA production. Finally, a sensitivity analysis was performed to identify the impact of the key process parameters on the economic and environmental performance. The results show that a variation of ±20% in the feedstock price can impact the MSP to vary ±7% and the global warming potential to vary ±12%.

“…This modularity allows for RMS application through simple piping changes without complex equipment alternations. The simulated moving bed process is a well-known example of a reconfigurable system, in which multiple columns are interchanged facilitating counter flow patterns of solid and liquid phases. − Previous studies have shown that reconfigurable membrane systems in amino acid processes provide economic benefits, especially with changes in product type or process disturbances . This study focuses on improving economic value in the evaporation process in amino acid production through reconfigurable evaporation processes.…”

The techno-economic impact of implementing a reconfigurable system in the integrated process was investigated, when L-threonine and L-valine were coproduced with a 5-effect preheater-integrated feed-forward evaporator, followed by singlestage evaporative crystallizers. A superstructure-based modeling and simulation framework was developed to consider all possible multieffect evaporator configurations. Evaporative capacity constrained by solubility limitations and fluid scaling was rigorously examined, providing the knowledge to select the most appropriate configuration and minimize steam consumption without compromising productivity. For L-threonine production, the 4−5−3− 2−1 sequence with a preheater showed the highest energy efficiency, with a maximum reduction of 8.4% in steam usage compared to the standard condition. For L-valine production, the 5−4−3−2−1 sequence without a preheater was most energyefficient, showing a maximum reduction of 7.3% in steam usage compared to the standard condition. These results clearly illustrate the agility of the reconfigurable multieffect evaporation system under various uncertain operational factors.
