System and method for mitigating dust migration at a wellsite
A system and method for mitigating dust migration at a wellsite is described. An oilfield material reservoir is provided for receiving oilfield material, the oilfield material reservoir having an enclosure. A dust collector is provided for collecting dust generated at the oilfield material reservoir, and a duct in communication with the enclosure and the dust collector is provided for transferring dust generated at the oilfield material reservoir to the dust collector.
1. A system for mitigating dust migration at a wellsite, comprising:
an oilfield material reservoir for receiving oilfield material;
a reservoir enclosure connected to the reservoir to enclose a substantially open portion of the reservoir and configured to mitigate dust migration from the reservoir;
an oilfield delivery vehicle having at least one compartment for storing the oilfield material;
a conveyor for transferring oilfield material from the oilfield delivery vehicle to the oilfield material reservoir, the oilfield delivery vehicle comprising at least one dust suppressant for mitigating dust generated during the transfer of oilfield material from the oilfield delivery vehicle to the conveyor;
a conveyor enclosure connected to the conveyor for mitigating dust migration from the conveyor; and
a dust collector for collecting dust generated at the oilfield material reservoir and the conveyor, the dust collector in communication, via at least one duct with the reservoir enclosure and the conveyor enclosure, the at least one duct configured to transfer dust generated at the oilfield material reservoir and the conveyor to the dust collector.
2. The system of claim 1 wherein the reservoir enclosure and the conveyor enclosure each define a ventilation pathway through which dust and air flow in an air-flow direction.
3. The system of claim 1 further comprising a blending apparatus in communication with the oilfield material reservoir for mixing the oilfield material with a fluid to form a slurry, wherein the blending apparatus comprises a blending apparatus enclosure configured to mitigate dust migration from the blending apparatus.
4. The system of claim 3 further comprising a duct in communication with the blending apparatus enclosure and the dust collector, the duct configured to transfer dust generated at the blending apparatus to the dust collector.
5. The system of claim 1 further comprising a receptacle between the oilfield material reservoir and the conveyor, the receptacle configured to collect falling oilfield material between the conveyor and the oilfield material reservoir.
6. The system of claim 1 further comprising a material transfer guide between the conveyor enclosure and the reservoir enclosure.
7. The system of claim 6 wherein the material transfer guide comprises a bellows.
8. The system of claim 6 wherein the material transfer guide defines an opening to allow air to enter the reservoir and define an air-flow direction for the system.
9. The system of claim 1 wherein the oilfield material reservoir is configured to receive a proppant.
10. The system of claim 1 wherein the dust collector comprises a vacuum assembly connected to the at least one duct to generate a flow path for transferring dust.
11. The system of claim 1 wherein the dust collector is adjoined to at least one compartment of the oilfield delivery vehicle.
12. The system of claim 1 further comprising a receptacle configured to collect falling dust and debris at a point between the conveyor and the reservoir.
