A centrifugal field-flow fractionation device includes an annular rotor, an arc-shaped channel member, a rotation drive unit, and a restriction unit. A channel member 16 is provided along an inner peripheral surface of the rotor, has therein a channel 161 for a liquid sample by laminating a plurality of layers, and has an inlet for the liquid sample to the channel 161 and an outlet for the liquid sample from the channel 161. By rotating the rotor, particles in the liquid sample in the channel 161 are classified by centrifugal force. A restriction spacer 64 restricts the channel 161 from being compressed to a height less than a certain height when the channel member 16 is compressed and deformed in a laminating direction.

An eggshell membrane separation system of separating a broken egg into an eggshell and an eggshell membrane (100) including: a pulverizer (10) that pulverizes the broken egg; an alkaline water tank (20) in which alkaline water is synthesized; and a separation tank (30) in which the alkaline water is supplied from the alkaline water tank and the broken egg pulverized by the pulverizer is separated into the eggshell and the eggshell membrane, wherein the alkaline water discharged from the separation tank is returned to the alkaline water tank (20) and reused. The eggshell membrane separation system can improve a separation property of an eggshell and an eggshell membrane and smoothly discharge the eggshell precipitated in the separation tank.

Processes and systems for the conversion of hydrocarbons herein may include separating an effluent from a moving bed reactor, the effluent including reaction product, first particulate catalyst, and second particulate catalyst. The separating may recover a first stream including the reaction product and first particulate catalyst and a second stream including second particulate catalyst. The second stream may be admixed with a regenerated catalyst stream including both first and second particulate catalyst at an elevated temperature. The admixing may produce a mixed catalyst at a relatively uniform temperature less than the elevated regenerated catalyst temperature, where the temperature is more advantageous for contacting light naphtha and heavy naphtha within the moving bed reactor to produce the effluent including the reaction product, the first particulate catalyst, and the second particulate catalyst.

A centrifuge for separating minerals by specific gravity is disclosed. The centrifuge rotates to circulate slurry across a collection region and to subject slurry in the collection region to centripetal forces that facilitate stratification within the collection region by the specific gravity of the constituent minerals of the slurry. Energy, such as acoustic energy, is coupled with the collection region and enhances the stratification by specific gravity within the collection region.

In a method for separating low density particles from feed slurries, a bubbly mixture is formed in a downcomer and issues into a mid region in a chamber. An inverted reflux classifier is formed by parallel inclined plates below the mid region allowing for efficient separation of low density particles which rise up to form a densely packed foam in the top of the chamber, and denser particles which fall downwardly to an outlet.
