Figure 8 . Results for the
bottoms liquid composition of the three MCD columns. The solid and
dashed lines indicate values from the ideal stage model for nitrogen and
argon, respectively, while points indicate the experimentally measured
values for each respective column. The number of stages includes the
condenser and reboiler, each of which represents one ideal stage.
These results are summarized in Table 1. Note that the HETP values
referenced previously in this work apply to the separation of binary
mixtures, where a single value is sufficient to describe the separation
of the two components. Air, however, is a mixture of more than just two
components, so the results are presented here in terms of separate HETP
values for nitrogen and argon.
Table 1. Results for each
MCD column. HETP values are relative to a column height of 25.4 cm, and
are thus in units of cm.
