Development of Air Quality Monitoring System for Preventive Maintenance in a Gas Plant

Toxic gases and pollutants in gas plants pose serious risks to workers, equipment, and the environment. This research introduces the design and development of an Air Quality Monitoring System (AQMS) aimed at supporting preventive maintenance in such facilities. The system combines low-cost sensors, wireless communication, and data analytics to detect and measure pollutants in real time. While current monitoring systems typically offer limited coverage and track only a few key pollutants, our approach addresses these shortcomings by enabling broader, more detailed monitoring across the plant. We tested the AQMS in an operational gas plant, where it proved effective in detecting potential hazards early and supporting proactive maintenance. The findings show that the system not only reduces the risk of accidents, equipment failure, and environmental harm, but also helps streamline maintenance schedules and lower operational costs.
