  • Drill-site proppant vacuum system
    Patent number: 9169706
    Abstract: A proppant collection system for a hydraulic fracturing well site, the well site having one or more proppant handling apparatuses and a closed proppant storage device. The system includes a dust capture system having a hatch in the one or more proppant storage devices, a dust collection cap on the hatch, and a conduit attached to each dust collection cap for receiving dust that enters the dust collection cap from the proppant storage device through the hatch. A central vacuum unit is attached to the conduits of the dust capture system, the central vacuum unit including a slurry tank for receiving dust that is collected by the dust capture system. The slurry tank is adapted to aggregate the dust collected from the proppant storage device.
