Gas Separation With Rotating Plasma Arc Reactor.
Hollis-DL Jr.; McLendon-JT; Davis-BE
An apparatus is described for separation of gas mixtures on the basis of the density of the components. It consists of a ball- shaped anode located within a cylindrical cathode chamber, between which an electrical arc is established at about 600 a at 22 V. There is a direct current magnet surrounding the assembly that is energized during operation of the apparatus to produce a magnetic induction field of 0.0030 T to 0.0265 T. The gas mixture to be separated is introduced into the space below the ball anode and the resulting plasma rotates electromagnetically at about 60,000 rpm as it passes between the electrodes. The heavier component thus moves to the outer wall of the chamber and may be removed by a suitable exit tube, while the lighter component remains in the center of the chamber and is likewise removed by a suitable exit tube.
