A system for separating particulates from a liquid prior to pumping of the liquid. The system is amenable to use, for example, in a wellbore environment for separating sand or other particulate matter from a production fluid. The system uses a sand separator, a submersible pump and a mechanism for reinjecting the particulate matter downstream of the pump discharge. This permits the sand and other particulates to be routed around the pump to reduce the potentially detrimental effects of such particulate matter on certain pumps.

Protection of downwell pumps from sand entrained in pumped fluids

A system for use with a hot oil fryer of the type which cooks food porducts in hot oil, in which particulates from the food are shed into the hot oil in the fry during the cooking operation, the fryer having an inlet to receive hot oil, and an outlet for recirculation of hot oil.

Removal of particulates from frying oils

A separation system for protecting a pump disposed in a well. The separation system separates sand from the well fluid prior to pumping of the well fluid. The separated sand, or other particulates is routed past the pump used in producing the desired well fluid. The sand is then reinjected into the produced fluid stream at a location downstream of the pump.

A centrifugal separator comprising a separation barrel with an upper end, a lower end, a central axis, and an internal circularly cylindrical axially extending wall forming a separation chamber, a collection chamber adjacent to the lower end, a spin plate extending across the separation chamber adjacent to the lower end, a solids slot adjacent to the lower end fluidly interconnecting the collection chamber and separation chamber, a closure containing the upper end having a centrally located exit port, an acceptance chamber wall surrounding the separation barrel adjacent to the upper end to form an annular acceptance chamber between the separation barrel and the acceptance chamber wall, a supply nozzle tangentially entering the annular acceptance chamber and forming a circular flow therein, and a plurality of radially spaced apart axially-extending slots passing through the wall of the separation barrel fluidly interconnecting the annular acceptance chamber and the separation chamber, entering the separation chamber tangentially in the same rotational direction as the rotational direction in the acceptance chamber, each of the slots having an upper end and a lower end; the slots being formed in a plurality of axially-disposed ranks, each rank including a plurality of equally angularly spaced apart slots, the upper ends of the slots in each lower rank having an elevation not appreciably higher than the lower ends of the slots in the rank just above it, the slots being formed in a staggered pattern.
