A method for removing fat from salvaged blood includes transferring salvaged blood from a reservoir to a blood component separation device, and separating the blood into a plurality of blood components. The method may then transfer a volume of unwashed blood components from the blood component separation device back toward the reservoir, and recentrifuge the blood components remaining within the blood component separation device. After re-centrifuging, the method transfers additional salvaged blood from the reservoir to the blood component separation device to refill the blood component separation device. The method may then wash the components within the bowl by introducing wash solution into the blood component separation device. The wash solution displaces a volume of fat from the blood component separation device and into a waste container. The method may then empty the washed blood components within the blood component separation device to a product container.

A rotating packed bed RPB (1) comprises a first and second packed bed (3, 4) both arranged on the same rotatable shaft (2). A gas is directed via a gas inlet (G in ) through the first packed bed (3) in co-current flow with a liquid in a radially outward direction towards the outer radius of the packed bed (3). The liquid enters the first packed bed via a first liquid inlet (5a). The gas exiting the first packed bed (3) is directed to the second packed bed (4) and forced through it in a radially inward direction in counter-current flow with a liquid, which enters through a second liquid inlet (5b). The arrangement allows an operation of the rotating packed bed with less energy compared to RPBs of the prior art operating in counter-current flow only. The apparatus allows low-cost design and a high design flexibility.

Die Erfindung bezieht sich auf eine Kontaktvorrichtung zum Stoffaustausch, welche einen Boden mit einem Kontaktteil, einem zusätzlichen Boden, einen Mantel mit Umfangsöffnungen, ein bewegliches 2-Wege-Ventil umfasst, wobei sich das letztere aus übereinander angeordneten und mittels Abstandsstütze gekoppelten Vollplatten zusammensetzt. Die Ursache-Wirkungsbeziehung zwischen diesen Merkmalen und die Betriebsweise der Kontaktvorrichtung beim Durchgang von Gas/Dampf wird dadurch verbessert, dass der Außenraum des Kontaktteils mittels eines Gehäuses durch die obere Reihe der Öffnungen im Mantel mit dem Innenraum des Mantels gekoppelt ist.

The invention relates to industrial processing technology, in particular to refining hydrocarbon liquids, to a method and device for the resonance excitation thereof and also to a method and device for the fractionating thereof. The inventive method for fluid resonance excitation comprises: a mechanical oscillation energy supply to the fluid with the aid of an energy source placed in the fluid and functioning on a frequency complying with a general low FN = F1N , where N>1 is a selected integer number, and F1= 63.992420 [kH] - is a basic oscillation frequency when N = 1. The device for resonance fluid excitation comprises a rotor with a working wheel embodied in the form of a disc and a circular wall provided with a row of output holes, and a stator having an input orifice connected to the cavity of the working wheel, and a coaxial wall. The inventive method for fractionating hydrocarbon liquids comprises preliminary treatment of the liquid with the aid of the above superposed device for resonance excitation, the supply of the preliminary treated liquid to a rectifying column and evacuation of distillated and residuum fractions. The inventive device for fractionating hydrocarbon liquids incorporates a feed pump, at least one rectifying column and said superposed device for resonance excitation.

This invention is directed to a cyclonic vapor/liquid contacting device, and distillation or related mass transfer or heat transfer processes employing its use, such as fluid catalytic cracking. Liquid feed is introduced near the floor of the cyclone via the downcomer or plenum. Vapor enters through sieve holes in the bottom of the cyclonic device. Near the floor are angled tabs or vanes that impart a spin to the vapor rising up through the floor. The tabs or vanes mix the liquid and vapor. The liquid is then thrown toward the cyclone wall where it exits through slots in the wall. A second set of tabs or vanes, located about in the middle of the cyclone, imparts additional spin to the vapor and entrained liquid rising through the cyclone. This improves liquid collection by the cyclone, especially in cases where a heavy liquid load dampens the spin action of the vapor in the base of the cyclone. In another embodiment, there is a non-spinning zone at the floor of the cyclone barrel which permits improved heat transfer between the liquid and vapor. If a non-spinning zone is used, the two sets of vanes or tabs are located at higher elevations within the barrel.
