| Popis: | We present the reactor simulation, multiobjective optimization, and the process intensification of biomass-derived polyesters: poly(1,5 pentylene 2,5-furan dicarboxylate) (PPeF), poly(1,5-pentylene 2,5-furandicarboxylate-co-1,5-pentylene succinate) (PPeFS), and poly(1,5-pentylene succinate) (PPeS). A plug flow reactor (PFR) was the first configuration considered, and the intensification of the polyesterification was done considering a reactive distillation (RD) and a divided wall column (DW) configuration. The process simulations along with the e-constraint optimization methodology and sensitivity analyses were implemented in Aspen Plus for a step-growth polymerization mechanism, where the segment concentration profiles, number molecular weight (Mn), and degree of polymerization (DPN) were estimated for each polyester, using poly(ethylene terephthalate) (PET) as the reference polyester. The Mn values obtained were in the range of 2300–4800 Da, suitable for coil coating applications, and the optimum operat... |
