FEED DELIVERY SYSTEM FOR A SOLID-LIQUID SEPARATION VESSEL

Номер: US20130140249A1
Автор: DIEP John, KIEL Darwin Edward, Sury Ken N., Sutton Clay Robert
Принадлежит:

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 inlets into the side of a series of parallel plates that form a series of channels which may be either vertical or inclined at an intermediate angle. This feed inlet flow conditioning system is characterized by a Channel Reynolds number of less than 3000. Such inlet flow conditioning is particularly useful where the feed has particles with a bi-modal size distribution to be separated from an overflow stream. The low Reynolds number combined with the influence of the walls serves to mitigate the upward flux of the smaller particles, for example mineral solids, by trapping the smaller particles within a matrix of larger particles, for example precipitated asphaltene aggregates. 1. A method of delivering a feed , the feed comprising a liquid component and a solid component into a separation vessel for separating the liquid component from the solid component , the method comprising:delivering the feed into the vessel through one or more inlets in the vessel into sides of a series of plates that form a series of channels of an inlet feed conditioner, wherein the feed is delivered with a Channel Reynolds number of less than 3000, to encourage smaller solid particles of the solid component to be incorporated into, or trapped within or under, or entrained down by, larger solid particles of the solid component, or aggregates of the larger solid particles, and to be carried to an underflow.2.

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. 1. A feed delivery system for use with a froth separation unit , the system comprising:at least one feed delivery pipe for delivering and conditioning the feed into the froth separation unit through one or more side inlets in a side wall of the froth separation unit; anda flow conditioning system, within the at least one pipe, for flow conditioning solvent-treated bitumen froth to a side-inlet Richardson number of equal to or greater than 1.0, the froth comprising bitumen, water, precipitated asphaltene aggregates, and mineral solids;wherein the flow conditioning system comprises a perforated sparger and a perforated plate, the perforated sparger being upstream of the perforated plate.2.

CLARIFIER WITH FEEDWELL AND METHODS OF CLARIFYING LIQUIDS

Номер: US20140091049A1
Автор: BRANDINO Lindsay
Принадлежит: ANDRITZ INC.

Certain examples relate to a new feedwell design for use in a clarifier that may better dissipate the entrance energy of the slurry-liquid combination exiting the feedwell and entering the clarifier. Plates of various shapes may be provided proximate to the bottom of the feedwell. The plates may cause a change in the flow direction of the feed, from mostly horizontal to mostly vertical, to slow the slurry. The provision of plates at the bottom of a feedwell in a clarifier may advantageously reduce the velocity of the materials entering the clarifier, or may increase the uniformity of the flow rate of the materials; while reducing or maintaining the amount of shear force, turbulence, or other forces that may have a detrimental effect on clarification. This may, in turn, permit solids to better “settle out” of the slurry-liquid combination, and thus improve the clarity of the removed liquid. 1. A feedwell for a clarifier comprising:at least one inlet pipe configured to introduce a slurry into an upper zone of the feedwell;a transition zone disposed below the upper zone; andone or more plates disposed proximate to an inner feedwell wall and a shaft at a bottom of the transition zone.2.

A spiral inertial filtration device is capable of high-throughput (1 mL/min), high-purity particle separation while concentrating recovered target particles by more than an order of magnitude. Large fractions of sample fluid are removed from a microchannel without disruption of concentrated particle streams by taking advantage of particle focusing in inertial spiral microfluidics, which is achieved by balancing inertial lift forces and Dean drag forces. To enable the calculation of channel geometries in the device for specific concentration factors, an equivalent circuit model was developed and experimentally validated. Large particle concentration factors were achieved by maintaining either average fluid velocity or Dean number throughout the entire length of the channel during the incremental removal of sample fluid. Also provided is the ability to simultaneously separate more than one particle from the same sample. 1.
