Separative Power of Ideal Cascade with Variable Separation Factors

Abstract

Concerning ideal cascades with separation factor varying from stage to stage, interstage flows are exactly determined by solution of the difference equation representing the conservation of the desired material flows. It is shown that, in such a cascade, the separative powers relevant to the desired and undesired materials are additive. This additive property is proved for the desired and undesired materials respectively by calculation establishing that the summation of separative powers of all stages is equal to the total separative power of the ideal cascade.
