The invention provides a method, apparatus and system for separating cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One exemplary method includes providing a first flow having a plurality of components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first cellular component of the plurality of components into the second flow while concurrently maintaining a second cellular component of the plurality of components in the first flow. The second flow having the first cellular component is then differentially removed from the first flow having the second cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.

Multi-valent metals, such as iron, may be removed from crude oil by introducing at least one metal removal chemical to the crude oil before, during or after the crude oil is charged to a settling tank. After mixing the metal removal chemical with the crude oil, the crude oil is kept still or held quiescent for an effective period of time to allow the metal species to settle to the bottom of the tank. Oil having reduced metal content may be removed from the top of the tank and/or metal-rich oil may be drained from the bottom of the tank or both. The crude oil having reduced metal content will cause fewer problems downstream in the refinery.

Multi-layer steam grid for heat and mass transfer in a tailings solvent recovery unit

Номер: US20120247944A1
Автор: Ali MILANI, Jianmin Kan
Принадлежит: Total E&P Canada Ltd

A grid of pipes for conducting steam at a pressure greater than a vessels' operating pressure and delivering the steam throughout the grid forms the internals for a tailings solvent recovery unit. The delivery of steam throughout the grid aids in maintaining a relatively low partial pressure throughout the vessel to act as a driver for mass transfer. Conducting the steam at the higher pressure through the pipes in the grid permits a surface of the pipes to be heated to a temperature higher than possible in a conventional vessel, increasing the heat transfer to the feed stream which flows through the grid.

A cross-flow is introduced at a predetermined temperature and of a predetermined chemical composition into the channel through a wall. This cross-flow flows at a first velocity and exits in a first direction through the other wall. An imposed field is applied on the particles in a second direction counter to the first direction of the cross-flow. The imposed field causes the particles to migrate at a second velocity opposite and/or equal to the first velocity of the cross-flow. Particles that are approximately balanced by the first and second velocities travel through the channel and are discharged in a fluid of predetermined chemical composition and at the predetermined temperature of the cross-flow.

Method of Processing a Bituminous Feed Using Agglomeration in a Pipeline

Принадлежит: ExxonMobil Upstream Research Co

The present disclosure relates to a method of processing a bituminous feed. The bituminous feed is contacted with an extraction liquor to form a slurry. The slurry is then flowed through a pipeline. A bridging liquid is added to the slurry to assist agglomeration. Agitation is also used to assist agglomeration. The result is an agglomerated slurry comprising agglomerates and a low solids bitumen extract. The agglomerates are then separated from the low solids bitumen extract. Performing the agglomeration in a pipeline as opposed to in a conventional agitating vessel may provide certain advantages, such as improved sealing in order to contain the potentially flammable mixture of oil sands slurry from the atmosphere, production of smaller and more uniform agglomerates due to improved mixing of the bridging liquid into the oil sands slurry, and the flexibility to have a long residence time for the extraction and agglomeration processes.

CLARIFIER WITH FEEDWELL AND METHODS OF CLARIFYING LIQUIDS

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.
