  • Dyed microspheres for characterization of photochemical reactor behavior
    Patent number: 7842512
    Abstract: A method for photochemical reactor characterization includes an application of using dyed microspheres exposed to UV irradiation under a collimated-beam system. Particle specific fluorescence intensity measurements are conducted using samples form the collimated beam and flow-through reactor results using flow cytometry. A numerical model may be used to simulate the behavior of the reactor system to provide a particle-tracking algorithm to interrogate the flow and intensity field simulations for purposes of developing a particle specific estimate of the dose delivery. A method for measuring UV dose distribution delivery in photochemical reactors is provided that includes introducing microspheres labeled with a photochemically-active compound in a UV reactor. The labeled microspheres are harvested downstream of the irradiated zone of a UV reactor and exposed to UV irradiation under a collimated beam of UV irradiation.
