Insight into the novel low cost green air pollution monitoring and control systems: A technological solution from concept to market

Abstract

Nitrogen oxide emissions, also referred to as NOx including NO and NO2 are hazardous to human life and have negative effects on the environment. Wet and dry treatments have both been explored as methods to significantly minimize these emissions. The wet process offers several benefits, the most notable of which are the flue gas adaptability, low operating temperatures, and the lack of poisoning and catalyst inactivation. In the research work, a NOX filter is being developed, with composite material for better transparency and non-reactive nature. Mechanical and electronic components have been employed to develop a stable and rigid experimental setup that effectively handles environmental challenges. Different tests are performed during performance analysis with known quantities of NOX through cylinders and varied the flow rate of ambient air. The concentration of NOX, H2O2, nitric acid, and other parameters were captured to get the optimum configuration that will provide maximum efficiency. The envisaged cost of implementing a solar tree-based air pollution monitoring and control system is estimated at $2796. This cost projection serves to exemplify the techno-economic analysis of the system, showcasing its potential to contribute to a cleaner environment and facilitate renewable energy utilization. The different financial model payback periods of the system are from 3.12 to 5.21 years. The developed system benefits people with respiratory health issues, elderly people, children, and infants, sports enthusiasts, traffic police persons, street hawkers or vendors, and people living in areas where the pollution level is high.
