In this work, a detailed study associated with the photo-Fenton degradation of the drug Paracetamol (PCT) in a pilot plant reactor is presented, using Computational Fluid Dynamics (CFD) modeling. Specifically, an emission model for a cylindrical lamp was developed and implemented in the OpenFOAM(R) platform, coupled to a multicomponent reaction mixture model to simulate the evolution of the different reactive species in the reactor. After experimentally validating the model, the influence of main operating conditions, such as oxidizing agent (HP) dosing strategies, recirculation flow rate (Qr) and the lamp configuration used on the effectiveness of the system was investigated. It was shown that the use of HP dosing strategies significantly reduces reaction times. It was observed that the PCT degradation rate remains unchanged as Qr increases, which allows the system to operate with a lower recirculation flow rate than that used in the experimental tests. The developed model facilitates the identification of reaction conditions that maximize PCT conversion, optimizing HP use and decreasing energy consumption.
