摘要:
Selon un procédé pour séparer une substance d'un liquide en liant cette substance à des particules fines, par exemple des solides, un récipient de liquide est soumis à un mouvement de rotation prolongé avec les particules dont la densité est inférieure à celle du liquide. Le liquide dont il s'agit de séparer ladite substance est mis en contact avec les particules de telle manière que ces dernières sont maintenues en suspension dans le récipient de liquide rotatif.
摘要:
A rotating processor (10) is disclosed. The apparatus (10) includes a hollow enclosed rotor (12), a rotor drive (104), internal space (24) to hold particulate porous reaction or separations media which may be porous, lines (40) connecting the center and periphera of the internal space with the exterior the through fluid line seals, valuing to control fluid flow, gradient makers, and a microprocessor to control and monitor the entire system. Optionally the rotor (12) may be spun with the axis vertical or horizontal, and may be used as a conventional column at rest. The rotating processor (10) permits any synthetic or separative process utilizing particulate or solid phase supports, or separations involving phases of different density to be accomplished under conditions which facilitate precise control of fluid flow and minimization of both micro- and macro-anomalous flow. A computer-controlled flat multiport valve system is also described to facilitate programmed scheduling of reagents through the rotor (12). Also disclosed are a process of synthesizing a polymer using the rotor (12) and a process of separating molecules using the processor (10).

A continuous contacting device is disclosed wherein a fluid stream may be contacted with particulate exchange materials. The device includes a plurality of rotating chambers (80, 132, 152) filled with particulate material. Fluid is supplied individually to these chambers through a plurality of feed ports (24, 52, 54, 56, 58) which are in periodic fluid communicating relation with each of the chambers. A plurality of fixed discharge ports (44, 104, 106, 108, 110) which are likewise in periodic fluid communicating relation with each of the chambers (80, 132, 152) is also provided. A process for continuously contacting fluids with the solid particulates is also disclosed.
摘要:
A liquid-solid contacting device which includes a plurality of chambers (101) for solid particulate material, such as zeolite for ion exchange is described. The chambers are mounted on a rotatable carriage (102) about a central axis (A). A cylindrical valve (301) at the central axis controls the flow of liquid to the respective chambers as the chambers rotate at a constant speed about the central axis. The valve arrangement controls both the flow into and out of the individual chambers, and includes a stationary cylinder (302) and a rotating cylinder (303). Outlet tubes (309) and inlet tubes (310) connect the chambers (101) individually to transitional tubes (416, 417) in the interior of the rotating cylinder (303). Stationary inlet ports (307) and stationary outlet ports (308) are provided in the stationary cylinder (302). As the rotating cylinder (303) rotates, the ports (426) are successively aligned with the ports (307) and the ports (427) are aligned with the ports (308) to allow flow of fluid through the tubes (305, 306).
摘要:
The invention relates to a method for regenerating the extractive potential of an organic hydroxyoxime-based extraction solution used in the recovery of metals by liquid-liquid extraction. The method is two-stage, in which a solid hydroxylamine is used in the reaction stage, and the removal of the undesirable compounds generated in the reaction occurs in the second stage by adsorption purification. The method of the invention is suitable for treatment of degraded oxime metal extractants in various process organic solutions both in aldehyde and ketoxime extractant solutions. The method can also be used to treat a mixture of degraded oxime extractants.
摘要:
An apparatus for continuous fluid-solid contacting includes a plurality of chambers (20) on a rotating carousel (30), each chamber having a supply conduit (22) and a discharge conduit (24), and a single valve (40) for controlling a supply and discharge of fluid to the chambers. The valve includes a stationary annular disk (50) having a plurality of conduits (44, 46) and a lower planar surface forming a disk valve face (54), and a rotatable annular plate (72) having an upper planar surface forming a plate valve face (74) and a plurality of holes (76) forming ports in the plate valve face. The plate is supported in pressurized contact with the disk valve. The frame supporting the chambers and the annular plate are rotated by separate devices. To ensure that the valve ports remain in rotational correspondence with the rotating chamber frame, the invention includes optical control for synchronizing the rotation of the frame and the rotation of the annular plate.
