How to Calculate Air Emissions (for AQMD AERs and …

20/1/2016 · Here's the general equation for calculating air emissions: The calculation tells us that the air emissions from any piece of equipment is equal to the activity rate (A) multiplied by the emission factor (EF), multiplied by one minus the control efficiency. If we have all of those components, we can calculate our emission rate for a single
