Patent number: 8591724Abstract: A method of delivering feed, for example a paraffinic solvent treated bitumen froth, to a separation vessel, for example a froth separation unit (FSU). The feed is delivered from one or more side inlets that may be substantially normal to, and flush with, the wall of the vessel. In contrast to certain conventional feed systems used in gravity separators which use a distributor plate to widely distribute the feed with a vessel, the feed is delivered such that it flows down the inside wall of the vessel. This feed delivery is characterized by a Richardson number of greater than 1.0. Such feed delivery is particularly useful where the feed has particles with a bi-modal size distribution to be separated from an overflow stream. The gentle flow serves to mitigate the upward flux of the smaller particles, for example mineral solids, by being trapped below the larger particles, for example precipitated asphaltene aggregates.Type: GrantFiled: May 14, 2010Date of Patent: November 26, 2013Assignee: ExxonMobil Upstream Research CompanyInventors: Clay R.

Publication number: 20130186576Abstract: Evaporation technology is commonly used to to treat process waters that contain low solubility salts. The technology typically used is a brine boncentrator which uses seeded slurry techniques internal to the falling film evaporator which allows these scaling salts to co-precipitate with the seed crystals instead of scaling on the heat transfer surface. Such systems often employ hydroclones to recover and recycle seed crystals that would otherwise leave the process with the brine blowdown stream. These hydroclones (or other separation devices) often have regions of tight clearance that are susceptible to plugging which can lead to suboptimal process availability and greater maintenance obligations. The inventors have developed an apparatus called a “settling chamber” for separating large solid particles from the feed stream to the hydroclone to eliminate plugging, improve availability and reduce maintenance requirements.Type: ApplicationFiled: January 18, 2013Publication date: July 25, 2013Inventors: Daniel P.

Patent number: 8318507Abstract: A method for the separation of particles of different densities using a step-wise gradient density extraction method as described herein where a sample is suspended in a liquid volume of an extracting medium of specific density and the particles that have a density less than or equal to that of the extracting medium of specific density can be recovered from a horizonatally rotatable hollow disk or a removable receptacle within a horizontally rotatable hollow disk designed for such purposes while the particles that have a density greater than the extracting medium of specific density form a deposit which can be cycled through the extraction process in an iterative fashion by varying the density of the extracting medium allowing the recovery of discrete particles of differing densities from a test sample.Type: GrantFiled: May 26, 2006Date of Patent: November 27, 2012Inventors: Marcus Joseph Horn, Wenkui Lan

Patent number: 8308958Abstract: A fluid clarification system and method is described in which fluid is passed through one or more settling compartments, each having a solids outlet at the base of the compartment. The base of each compartment includes inclined surfaces for guiding settled solids to the outlet. Also described is a polymer reaction trough including baffles to promote gentle mixing of inflow fluid with flocculant. The system is designed to reduce costs of transportation, flocculant, and solids handling. The system is preferably arranged to facilitate transport on a skid or trailer, while maximizing fluid handling capabilities and minimizing costs.Type: GrantFiled: May 25, 2011Date of Patent: November 13, 2012Inventor: Scott Blair Godlien

Publication number: 20120267324Abstract: The present invention relates to a delamination method for recovering constituents of a paper-based multi layered laminated packaged waste. The method comprises using of a mixture of inorganic bases to separate the constituents of the packaged waste and recover paper, plastic and/or aluminium components separately. The paper can be recovered as pulp, the plastic can be recovered as is, and the aluminium can be recovered as a water soluble salt. The delamination method of the present invention is also effective on cardboard-based multi layered laminated packaged waste.Type: ApplicationFiled: December 20, 2010Publication date: October 25, 2012Inventor: Ashutosh Mukhopadhyay

Patent number: 8282839Abstract: A floating separating element for use in centrifugal separation of components of a physiological fluid comprises a positioning part and a separating part, where the positioning part is designed to automatically assume a position in a supernatant and a separating part is positioned at a desired location with respect to the interface between the supernatant and heavier components. In preferred embodiments the physiological fluids are blood or bone marrow aspirate, and the heavier components comprise red blood cells. The positioning part comprises the majority of the mass of the separating element and is thin so that differences in the position of the separating element with respect to the interface are small compared to differences in the densities of the separated components, particularly the component comprising red blood cells. A method allows red blood cells to move the separating element during decanting to ensure complete decant of the supernatant.Type: GrantFiled: August 2, 2011Date of Patent: October 9, 2012Assignee: Harvest Technologies CorporationInventor: James R. Ellsworth
