Abstract

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.

Abstract

A cyclonic separator is provided, comprising at least one cyclonic chamber in the form of a cylindrical tube, having an upper inlet end and a lower liquid outlet end, at least one involute chamber located adjacent to and in fluid communication with the upper end of each of the at least one cyclonic chambers. The involute chamber comprises an involute inlet and a gas outlet proximal an upper end of the involute chamber. An inlet manifold is in fluid communication with said at least one involute chamber via the involute inlet. Said involute inlet of said involute chamber is laterally separated from said gas outlet. A method is further provided for separation of a mixed heavy phase/light phase process stream.

Abstract

A cyclonic separator is taught, comprising at least two cyclonic chambers in the form of cylindrical tubes, having an upper inlet end and a lower liquid outlet end, a common tangential inlet in fluid communication with the upper end of each of the at least two cyclonic chambers, a gas outlet proximal to and extending upwardly from the upper ends of each of the at least two cyclonic chambers and a common outer shell surrounding the at least two cyclonic chambers, wherein said common tangential inlet extends through said common outer shell and into each of said at least two cyclonic chambers. A method for separation of a mixed heavy phase/light phase process stream is also taught.
