Abstract: Apparatus and method for reducing airborne proppant adjacent a fracking material handling system. In some embodiments, a proppant storage chamber is configured to store a volume of proppant. A blow-in adapter mates with a first port of the chamber to facilitate a flow of proppant into the chamber at an inlet pressure. A filter assembly covers and filter a first aperture of the chamber to reduce an emission of airborne proppant during the transfer of the proppant into the proppant storage chamber. A vacuum adapter mates with a second port of the chamber to supply a negative pressure to the chamber during the filling process to maintain an internal pressure within the chamber below a predetermined pressure threshold.

Abstract: Apparatus for reducing airborne proppant adjacent a fracking material handling system. In some embodiments, a proppant reduction cover is mounted over a first aperture of a proppant storage chamber and has a permeable filter material adapted to facilitate a first flow of displaced air therethrough as proppant is loaded into the chamber. A vent sock is mounted over a second aperture of the chamber and has a permeable filter material facilitate a second flow of displaced air therethrough during the loading of the proppant. A vacuum adapter is mounted over a third aperture of the chamber to apply a negative pressure to an interior of the proppant storage chamber during said loading of the proppant.

Abstract: A filter used to reduce the emission of silica particles used in hydraulic fracturing. The silica reduction cover is a custom fit filter installed onto vent hatches of proppant storage trailers. Proppant storage trailers, or “frac sanders,” have a series of vent hatches that release air and fine particles into the atmosphere during material transfer operations. The silica reduction cover is comprised of filter material and permits the controlled release of high pressure air at each vent hatch while reducing sand particle loss. The silica reduction cover maintains proppant sand product in the trailer for production use while significantly reducing the emission of airborne sand particles in the immediate work and adjoining site areas. The silica reduction cover incorporates a viewing window so that workers may monitor proppant levels in the storage trailer while the silica reduction cover is installed.
