A CFD study of an annular pilot plant reactor for Paracetamol photo-Fenton degradation

چکیده
This work studies in detail the photo-Fenton degradation process of Paracetamol (PCT) on an annular pilot-plant reactor using Computational Fluid Dynamics (CFD). A cylindrical lamp emission model was originally implemented over structure OpenFOAM(R) platform and a multicomponent reaction mixture used to compute temporal evolution different species at each point reactor. Once proposed experimentally validated, influence operating conditions (i.e. strategies for hydrogen peroxide (H2O2) dosage, use low recirculation flow rates (Qr), completely uncovered setup) studied. The results analysis showed that double addition H2O2 (50% before tank 50% reactor) significantly reduces times process. Moreover, overall PCT rate does not change when Qr is increased, thus allowing system be operated with three lower than one experiments. Thereby, developed allows identifying maximize conversion, making efficient (main chemical reagent) reducing electrical energy consumption (recirculation flow) by under present large-scale photochemical reactors.

متن کاملMathematical modelling of an annular photocatalytic reactor for methylene blue degradation under UV light irradiation using rGO-ZnO hybrid
The application of heterogeneous photocatalysis in industrial scale has been hindered by a lack of simple mathematical models that can be easily applied to reactor design and scale-up. This work intends to use a simple mathematical model for predicting methylene blue (MB) degradation in a slurry-annular photocatalytic reactor using zinc oxide (ZnO) hybridized with reduced graphene oxide (rGO)-Z...
متن کاملTreatment of a sanitary landfill leachate using combined solar photo-Fenton and biological immobilized biomass reactor at a pilot scale.
A solar photo-Fenton process combined with a biological nitrification and denitrification system is proposed for the decontamination of a landfill leachate in a pilot plant using photocatalytic (4.16 m(2) of Compound Parabolic Collectors - CPCs) and biological systems (immobilized biomass reactor). The optimum iron concentration for the photo-Fenton reaction of the leachate is 60 mg Fe(2+) L(-1...
