This work considers a separation process and the attendant losses on the basis of thermodynamic analogies. Energy—oriented efficiency as a criterion of the process, and the entropy—oriented efficiency as a criterion of its results, are compared. An example shows that the values are close to each other. As a practical recommendation, a modification of the feeder system is suggested.
