| Abstract: | Rectification and separation processes generally operate far
from their thermodynamically optimal conditions. Because the rectification
process is one of the most widespread and energy-consuming processes of
chemical technology, estimates of its limiting possibilities and the optimal
profiles of concentrations that correspond to it are very important. In this
paper we first find an estimate of the reversible rectification efficiency and
the connection of this efficiency with entropy production. Then we derive the
conditions on the profiles of concentrations that provide minimal
irreversibility for a mass transfer process which has a specified intensity.
Finally we determine an estimate of the limiting performance of the
rectification process based on the results obtained. |
