Abstract
An improved process and apparatus for separating solid particulate from a gas stream having the same entrained therein. The separation is accomplished with a magnetic separator comprising a plurality of electro magnets disposed generally around or within the periphery of the gas stream or extending through a cross-section thereof, which magnets are operated such that continuous separation is possible. When the solid particulate is not, normally, subject to magnetic attraction, the same may be rendered subject to such attraction by incorporating a suitable compound therein. This is most conveniently accomplished by adding a precursor of such a compound to the process in which the solid particulate is formed at a point after which the subsequent process steps would result in the conversion of the precursor to a suitable material. The particulate is, of course, separated from the gas stream by magnetic attraction and is then withdrawn from the solid separator by 'turning off' the electro magnet or magnets.
