Opacity Monitoring Provincial regulations stipulate that our Dalhousie plant must report an exceedance if we exceed 20% opacity in any 4 minutes of a 20 minute period > Very difficult to calculate using DCS > Many spikes due to rapping Solution - PI-API!

Opacity Monitoring NT service written in C Runs on PI server Tracks opacities for each unit Should an exceedance occur, it > generates a report of opacities during the period > alarms the unit operator NT service written in C Runs on PI server Tracks opacities for each unit Should an exceedance occur, it > generates a report of opacities during the period > alarms the unit operator
