I have been reviewing some old documentation for environmental permitting at the facility I work. We use filter baghouses with forced draft to collect dust from unloading processes. The material is unloaded to the baghouse then is gravity fed from the baghouse through a rotary valve to the tankage below. The estimate for the particulate emissions uses a "98% of the material drops out due to velocity change and is not part of the baghouse loading". Has anyone ever heard of this? It seems likely that the filters will not have filter the entire loading as the solids will drop below, but I am unfamiliar with this usage, especially considering Potential to Emit Calculations.
Any thoughts?>
