Determine whether the change in distillation column temperature is related to composition or to pressure
The question is a bit confusing! Changes in pressure within the tower will inevitably lead to changes in temperature within it, and changes in the feed composition will also affect temperature variations
The effect on the components is relatively significant and easy to detect; it can generally be identified in the pre-tower. As for the effect of pressure, as long as it remains within the limits specified by the process requirements, along with the appropriate temperature and reflux ratio, the product will be of satisfactory quality.
It’s related to temperature; a decrease in temperature indicates an increase in the light components at the top of the tower
