ABSTRACT:
A separation device for removing solids from an input stream is provided, comprising a vessel, such as a production vessel or storage tank, having an inlet for receiving an input stream containing fluids, such as oil and water, and solids, such as sand and silt. The vessel also includes a fluid outlet and a drain outlet. An optional fluid recirculation and injection device is mounted inside the vessel and delivers fluid to facilitate removal of the solids through the drain outlet. The vessel also includes an agitation or flighted device mounted adjacent to the drain outlet for contacting and dislodging solids which have settled within the vessel. The agitation device includes a rotatable shaft driven by a motor, and an agitation element, such as an auger, to break up the solids and move them toward the drain outlet. A method of removing solids is also provided using the auger device.
