<p>The sepn. of mixts. of two gases, two liqs., a gas with a colloid, or a liq. with a solid, and based on differing molecular weights or specific gravities is effected by pressure diffusion using varying pressure fields. These fields are two-dimensional mutually perpendicular wave fields operating at the same frequency but with pi/2 phase shift. The mixt. for sepn. is fed by co-current or counter-flow perpendicular to the vibration plane along the longitudinal axis of a prismatic sepn. chamber with the sepd. components leaving at the roof of the chamber. The wave-fields can be formed by two vibrating walls, each tuned to the natural frequency of the standing waves. A circular polarised wave field produced by a single vibrating wall and reflecting wall, or by tubular valves, may be used. The method separates a variety of mixtures, in particular gaseous isotopes, with high efficiency and low power consumption. No moving parts or pressure compressors are involved.</p> |
