Patent number: 7934606Abstract: The induced vortex particle separator is a device for separating solid particulate matter from a liquid containing such particulate matter. The liquid enters a housing through an inlet port and is driven about a helical vane to form a helical flow path. Upon exiting the helical vane, the liquid is received within a central portion of the housing where a centralized structure including an annular stator and an inverted diffuser cone drive the liquid to form a free vortex. Under centrifugal force, the solid particulate matter is separated from the liquid and flows, under the force of gravity, into a lower region of the housing. Due to a negative pressure differential, the liquid is driven upwards within an inner cylindrical shell mounted within the housing to flow into a siphon for output through an outlet port.Type: GrantFiled: March 27, 2008Date of Patent: May 3, 2011Assignee: Advanced Petroleum Technologies, Inc.Inventors: Boyd B.

Publication number: 20030222003Abstract: An arrangement of hydrocyclones, resulting in a greater density of hydrocyclones packaged in a given volume. One or more overflow extensions is secured to the overflow portions of one or more hydrocyclones to permit individual hydrocyclones to be placed into an axially staggered arrangement with respect to each other. By keeping the larger hydrocyclone heads from being directly adjacent that of a neighbor's, the maximum diameter of the hydrocyclones no longer becomes a limitation on the proximity of one hydrocyclone to another. The inlet section of one of a group of hydrocyclones is disposed to be adjacent either the separation portion of an adjacent hydrocyclone or an overflow extension, thereby permitting denser packaging. In another aspect, groups of axially staggered hydrocyclones are axially offset from and intermeshed with one another, permitting greater density in packaging.Type: ApplicationFiled: April 23, 2003Publication date: December 4, 2003Applicant: Petreco International Ltd.Inventor: Keith J.
