Boiling temperatures of the pure substances:

Ï‘_{B} = 80,1 Â°C and Ï‘_{T} = 111 Â°C (p. 110/111)

Boiling temperatures in Kelvin:

T_{B} = 80,1 + 273,15 = 353,25 K

T_{T} = 111 + 273,15 = 384,15 K

Rose separation factor (p. 256):

Function equation for the equilibrium curve (p. 256):

For example for the substance quantity proportion in the feed:

Minimum return ratio (p. 257):

Selected (p. 256): v = 2 Â· v_{min} = 2 Â· 2,39 = 4,78

Function equation for the gain line (p. 256):

or straight line between the ordinate intersection and the intersection of the perpendicular over x_{D} with the diagonal.

For the ordinate intersection (p. 256):

Point of intersection with the diagonal: y_{D} = x_{D}

_{ }Intersection straight line is, since inlet boils liquid, the vertical above x_{Z} . The output straight line is constructed between the intersection point of the intersection point straight line with the reinforcement straight line and the intersection point of the perpendicular above x_{B} with the diagonal.

Drawing the steps between equilibrium curve and gain line and equilibrium curve and output line, starting from x_{D} to over x_{B} . There are **7 theoretical stages** in the amplifier section and 4**stages in the output section** (without consideration of efficiency and buffer floors).
