A tribo-electro static separation process and system for the preparation of various food and feed products. A tribo-electric separation process and system for fractionating a feed mixture comprising at least two members of the group of proteins, starches, soluble and insoluble fibers. Namely, supplying a feed mixture comprising at least two of the group of proteins, starches, soluble and insoluble fibers to a tribo-electric separator and simultaneously charging and separating the feed mixture into at least two subfractions, with one of the subfractions enriched in one of protein, starch and fiber and having a composition different than the feed mixture.

Process for separation of dry food and feed materials using a tribo-electrostatic separator device

A method for removing ammonia from coal fly ash contaminated by ammonium salts is disclosed. The method involves the addition of small amounts of water, and in some cases, small amounts of an alkali source, to the fly ash to liberate the ammonia trapped therein. The ammonia liberation may be further aided by vigorous mixing of the fly ash.

Apparatus and method for separating carbon particles from flyash includes one of increasing a relative humidity of the flyash or decreasing the relative humidity of the flyash to within an optimum humidity range, and introducing the flyash within the optimum humidity range into a triboelectric separator so as to triboelectrically charge the carbon particles and the flyash and so as to electrostatically separate the charged carbon particles from the charged flyash.
