Abstract
In this study, depolymerization via neutral hydrolysis has been used to co-process polyester and nylon 6 into its constituent monomers. While the study has been performed as a pure literature study, it has been concluded that co-processing of the two polymers is feasible. The recovery of the monomer products by phase separation has been investigated with the objective of retaining high yield and product purity utilizing Aspen Plus V9. TPA and CL have been identified as the main products of the process based on which the solid-liquid phase separation to retrieve the monomers has been implemented. 605.3 kg TPA/hr has been recovered with 99.9% purity and 484.7 kg CL/hr as liquid with 91.2% purity. The separation of water and EG has been modelled additionally to give the possibility of recycling a portion of the process water within the system. To improve energy recovery, a pinch analysis has been conducted to identify the optimum HEN of the model.
