Many different modes of column operation and control can be visualized, but for preparing programs, we must keep in mind at least four needs:

1. Column gains for feedback control. Here, for example, we need to know the change in top composition due to a change in distillate or reflux flow with other variables held constant.

2. Column terminal composition sensitivity to changes in feed rate, feed enthalpy, feed composition, and column pressure (usually defined at column
