| 제목 | Simulation of BHET (bis(2-hydroxyethyl) terephthalate) production process by glycolysis of PET (polyethylene terephthalate) |
| 초록 | Polyethylene terephthalate (PET) is one of the most versatile polymers used extensively for the fabrication of polyester fiber, soft drink bottles, and photographic films. Its use has increasedtremendously in recent years. The current proliferation of PET poses serious environmental and economic concerns. Recycling of PET into its monomer BHET is a promising choice to solve these problems. BHET production from PET glycolysis is simulated and the yield of BHET is optimized using Aspen plus®. In this study, we consider glycolysis of PET at 265 oC and 0.6 MPa. Influence of various parameters such as temperature, PET : EG ratio, and concentration of catalyst on the yield of the glycolysis productsare investigated. Poly-NRTL modelis used for phase equilibrium thermodynamics. The largest yield of BHET from PETwas 85 mol %. |
