Abstract

A proposed total separation index of a physical separation system used for more than three products was reviewed based on five conditions described by Schulz. That consideration showed that no total separation index of a separation system fulfilling all required conditions has been proposed to date. Furthermore, the total separation efficiency of an n-product system was confirmed to be expressed by the formula of m=d1/(n−1) using the determinant, d of a recovery matrix. The index of m is exactly the total separation efficiency predicted by Aoki. This index is demonstrated to fulfill all five conditions. Moreover, it has the physical meaning of a perfectly separated feed rate, thereby enabling the extension of an n-product system. This extended separation efficiency, ESE and universal separation efficiency proposed by Salama were compared through a simulation using random numbers.
