Differences between gas separation cascade work and the work of isobaric–isothermal mixing

Abstract

The change in entropy at the nodes of the a separation cascade during the processing of a multicomponent mixture is calculated. A thermodynamic interpretation of the nature of the difference between the work of the cascade, determined from the separation potential and the thermodynamically estimated work of the isobaric–isothermal mixing of the fractions released at its ends, is presented.
