One illustrative cyclone separator disclosed herein includes an outer body, an inner body positioned at least partially within the outer body, an internal flow path within the inner body, the internal flow path having a fluid entrance and a fluid outlet, a first fluid flow channel between the inner body and the outer body, and a re-entrant fluid opening that extends through the outer body and is in fluid communication with the fluid flow channel, wherein the re-entrant fluid opening is positioned at a location upstream of the fluid entrance of the internal flow path in the inner body.

A fluid treatment system, a fluid processing apparatus and a method of treating a mixture are provided in which a separator has two outlets for different components of mixed fluid. A conduit connecting one of the outlets of the separator to the inlet of the separator is provided to recycle fluid from an outlet of the separator back to the inlet and a pump at the inlet of the separator regulates the fluid flow through the separator at a constant rate. As a result, the flow rate through the separator is increased, which increases the separation efficiency of the separation system. The conduit also functions as a bypass line should the flow of fluid be obstructed through the separator. The conduit may preferably be operated in conjunction with an energy harvester.

The present invention addresses to a third stage system with self-bleeding by means of the use of an internally or externally installed ejector with application in all multicyclone systems operating at positive pressure, whether for application in particulate abatement or protection systems of turbo-expanders or in industrial units that involve the need of recovering solid products carried by the process gas, aiming at eliminating the need for any additional separation systems using cyclones or filters to carry out the bleeding of the cyclone legs.

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.
