A cyclone type liquid/gas or liquid/liquid separator having separation properties that are stabilized, even when the flow rate and the proportions of the liquid phases for separation vary, by means of a platform situated in the low portion of a cylindrical separation chamber that is fed at its top end via a tangential feed orifice. An installation and a method are also provided for separating the oil and water contained in crude oil, with the help of a cyclone separator.

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.

The present invention relates to a cyclone separation device for separating particles from air and a cyclone vacuum cleaner (80). It has the objective to reduce noise without impairing the dirt separation performance. This is achieved an arrangement comprising a cyclone chamber (10), a dirt collecting chamber (50) arranged adjacent to the cyclone chamber (10) for collecting dirt particles separated from air, a dirt-duct (40) between the cyclone chamber (10) and the dirt collecting chamber (50) for allowing dirt particles to pass from the cyclone chamber (10) towards the dirt collecting chamber (50), and an air-guide (60) arranged adjacent to the dirt-duct (40) for reducing the momentum of the air in the dirt-duct (40).

A dynamic particle separator is described for cyclone separation of sand from a gas stream in connection with petroleum related production of oil and gas, where the separator comprises a housing (14) containing as cyclone tank (4) that is equipped with an upper inlet opening (1) for the gas stream and an upper and a lower outlet opening (2,12) for export of gas and particles, respectively, from the tank (4). The cyclone tank (4) is formed, at least in an internal area around the inlet opening (1), with an upper and downwardly directed conical shape (4a) that increases in diameter, and where the upper conical shape (4a) thereafter has a transition into an inverse, lower conical shape (4b) that converges towards the lower outlet opening (12).

A cyclone separator useable in a surface cleaning apparatus comprises a cyclone chamber and a dirt collection chamber exterior to, and surrounding at least a portion of the cyclone chamber. The dirt collection chamber is in communication with the cyclone chamber via a dirt outlet. An air flow passage extending to the cyclone air inlet travels generally axially through the dirt collection chamber.

A part-conical section (20,22) for use as part of a separation chamber (14) of a hydrocyclone (10) is described. The part-conical section comprises: an upper end defining internal and external diameters and including an upper mount (44,48); a lower end defining smaller internal and external diameters than the upper end, and including a lower mount (46,50); and a side-wall (26) defining an internal passageway (28) along a fluid transport axis (30) and an external surface. The internal passageway extends from the upper end to the lower end and defines a radially-inward tapering portion with respect to the fluid transport axis, and a non-inwardly-tapering portion with respect to the fluid transport axis. The tapering portion extends from the upper end to the non-inwardly-tapering portion, and the non-inwardly-tapering portion extends from a narrow end of the tapering portion to the lower end. A spigot (24) and a hydrocyclone (10) are also described.
