Diagram of a gas centrifuge with countercurrent flow, used for separating isotopes of uranium. A gas centrifuge is a device that performs isotope separation of gases. A centrifuge relies on the principles of centrifugal force accelerating molecules so that particles of different masses are physically separated in a gradient along the radius of a rotating container.
To investigate this problem Svedberg developed an analytical centrifuge, equipped with a photographic absorption system, which would exert a much greater centrifugal effect. [24] In addition, he developed the theory necessary to measure molecular weight. [25] During this time, Svedberg's attention shifted from gold to proteins. [24]
Gas centrifuges, including Zippe-type centrifuges, for isotopic separations in the gas phase. Industrial centrifuges may otherwise be classified according to the type of separation of the high density fraction from the low density one. Generally, there are two types of centrifuges: the filtration and sedimentation centrifuges.
A laboratory centrifuge is a piece of laboratory equipment, driven by a motor, which spins liquid samples at high speed.There are various types of centrifuges, depending on the size and the sample capacity.
The feed product is pumped into the decanter centrifuge through the inlet. Feed goes into a horizontal bowl, which rotates. The bowl is composed of a cylindrical part and a conical part. The separation takes place in the cylindrical part of the bowl. The fast rotation generates centrifugal forces up to 4000 x g. Under these forces, the solid ...
The centrifugal force creates a pressure gradient: On the axis of the centrifuge there is practically vacuum, so that no mechanical feedthrough or seal is needed for the gas inlet and outlets; near the wall the UF 6 reaches its saturation pressure, which in turn limits the rotation speed, because condensation must be avoided.
Gas separation can refer to any of a number of techniques used to separate gases, either to give multiple products or to purify a single product.
A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.
