“…In a similar study comparing ray tracing with the reverse Monte Carlo method for application to a GEO orbit, Benacquista et al concluded that the ray tracing method is fast, but presents intrinsic limitations that need to be verified before further use 28 . Monte Carlo simulations have been used in the literature for reactor modeling and have been proven to be time-consuming and require a large computational space 29 – 31 .…”

Background Measurement of light intensity reaching a point of interest in complex systems is a challenge faced by academia and industry. This study analyzes an optical ray tracing method to predict the radiant intensity reaching a point of interest in a germicidal system. Methods Implementation was performed by analyzing how the method compares with the discrete ordinate method, radiometry, and actinometry. This study further quantified the effect of the photoreactor quartz tube on the measured intensity for multiple wavelengths. Results Light intensity losses were estimated to be 10 ± 0.5% for the FX-1 265 source. In contrast, the simulation in a water medium showed an increase of up to 64% in the light intensity delivered to the central part of the tube owing to internal reflections and scattering. Model predictions from ray tracing were successfully compared with the discrete ordinate method (DOM) and experimental data (within ± 6%), ensuring the accurate design of complex systems for water disinfection. Conclusions The data from simulations address the challenges faced in complex radiation modeling and demonstrate that the method can be utilized as a useful tool for optimization and prediction.

“…However, despite strong research efforts from the past two decades (i.e., adopting various high-pressure reactor designs (plug flow tubular, fluidized bed, and autoclave reactors), homogeneous, and heterogeneous catalysis), the hydrothermal processing of waste is still an immature technology at a low technological readiness level (TRL) . Large-scale commercialization requires advancements in different areas, such as (i) maintaining robust operation by reducing the negative effects of reactor plugging and corrosion, (ii) mapping process integration and intensification possibilities to lower energy requirements, and (iii) gathering critical know-how on fuel gas valorization strategies yielding high-value products.…”
