How It Works
1
Continuous Monitoring
Five sensor stations positioned around the refinery perimeter measure non-methane hydrocarbon (NMHC) levels every 5 minutes, 24 hours a day.
2
Data Analysis
Readings are processed with 5-minute and 1-hour averaging periods. Meteorological data including wind speed and direction is captured alongside each reading.
3
Public Alerts
When VOC levels exceed 730 ppb, the system automatically sends email alerts to subscribers. Monthly reports are generated for the public record.
Features
Interactive Map
Color-coded sensor markers on a satellite map showing real-time VOC levels at each station. Green (< 500 ppb), yellow (500–730 ppb), or red (> 730 ppb) at a glance.
Real-Time Dashboard
Live readings with 5-minute and 1-hour averaging for every station. Track current conditions, see trend arrows, and monitor wind data — all in one view.
Instant Alerts
Automatic email notifications when VOC levels exceed 730 ppb or when a sensor goes offline. Smart deduplication so you only get notified when it matters.
Reports & History
Historical trend charts with 24-hour, 7-day, and 30-day views. Automated PDF reports generated daily, weekly, and monthly — downloadable anytime.
Notifications
VOC (NMHC) & SO₂ Exceedance
Immediate alert when any station's 1-hr block average exceeds 730 ppb VOC (NMHC) or 75 ppb SO₂.
Instrument Outage
Get notified when a sensor station goes offline or stops reporting, so you know if there's a gap in coverage.
Report Available
Notification when a new daily, weekly, or monthly report has been generated and is ready for download.
