Link to paper: https://www.sciencedirect.com/science/article/pii/0009250973800259

According to Table A1 in the appendix, the typical steady state operating conditions are:

Composition

Top: 96 wt% methanol
Bottoms: 0.5 wt % methanol
Feed: 46.5 wt % methanol

Flow Rates

Top product: 1.18 lb/min
Top reflux: 1.95 lb/min
Bottoms: 1.27 lb/min
Steam: 1.71 lb/min
Feed: 2.45 lb/min

Note: The paper mentions the transfer functions for feed as a disturbance on page 1714:

$G_{BF}$ - transfer function, relating bottoms composition to feed flow rate
$G_{DF}$ - transfer function, relating overhead composition to feed flow rate

But I don't see the actual transfer functions in the paper? Other papers citing this paper has the TFs but where did they get them?
