Example | Calculate the fugitive emissions" and the stack emissions if the process equipment generates 100 1b./hr of particulate matter, the hood capture efficiency is 95%, and the collection efficiency of the air pollution control device is 95%. The USEPA defines fugitive emissions as "emissions that (1) escape capture by process equipment exhaust hoods; (2) are emitted during material transfer; (3) are emitted to the atmosphere from the source aren' and (4) are emitted directly from
