A HiGee form of this technique uses centrifugal acceleration to force horizontal flow, while another uses a dividing wall. Molecular sieves remove water and carbon dioxide upstream of a cryogenic form of this technique. The Kirkbride equation can be used to calculate the inlet location in this technique whose shortcut form uses the FUG method. The Q-line on a McCabe–Thiele diagram represents the feed in this technique. This technique may employ a Dean–Stark apparatus to remove water. Purity of products from this technique can be enhanced by increasing the reflux ratio. Adding a component to mixtures in this technique to break azeotropes can separate water and ethanol. For 10 points, what physical process separates components of a liquid mixture by their boiling points? ■END■
ANSWER: distillation [accept specific forms like fractional distillation or azeotropic distillation or HiGee distillation]
