A particle separator is provided for separating small particles from large particles from material. The particle separator includes a conical shaped separator housing that forms a cyclonic separator enclosure, a cover attached at a top portion of the cyclonic separator enclosure, and an opening at a bottom portion of the cyclonic separator enclosure. The cyclonic separator enclosure has an inlet tube with a tangential entry opening along an inner wall of the cyclonic separator enclosure, where the inlet tube projects horizontally outward from an upper portion of the cyclonic separator enclosure. An outlet tube extends upward from a center of the cover with a vacuum unit connected to the outlet tube that creates a vortex in the cyclonic separator enclosure.

A cyclonic separator is taught for separation of a mixed liquid phase/gas phase process stream. The cyclonic separator comprises an outer shell, at least two cyclonic chambers located within the outer shell, each cyclonic chamber having an upper end and a lower end; a single, common tangential inlet passing tangentially through the outer shell and into each of the at least two cyclonic chambers, proximal the upper ends thereof; a gas outlet tube located at least partially within each cyclonic chamber, extending axially from a lower gas outlet end located below the tangential inlet, to an upper gas outlet end extending out of each of the at least two cyclonic chambers, said upper gas outlet ends being in fluid communication with a common gas chamber located above the outer shell; and a circumferential recycle opening formed around and through a thickness each gas outlet tube, in a portion of each gas outlet tube located axially between the upper end of cyclonic chambers and the common gas chamber, said recycle opening thus being in fluid communication with an inside cavity of the outer shell.

A vortex breaker for a particulate separator has a first set of vanes spaced along a perimeter of a first shape and a second set of vanes spaced along a perimeter of a second shape, where the second shape resides within the first shape. Each of the vanes has a top edge, a bottom edge, an inside edge, and an outside edge. The vanes in the first and second sets of vanes intersect the first and second shapes, respectively. The vanes in the first set are oriented in a first rotational direction, and the vanes in the second set are oriented in a second rotational direction that is opposite the first rotational direction. The first set of vanes and the second set of vanes define fluid flow paths between the outside edges and the inside edges of the sets of vanes.
