Question
This piece of information is calculated from Kirkbride’s correlation after applying the FUG (“F-U-G”) method. For 10 points each:
[10h] Name this design criterion. A graphical method calculates this information by determining where the q line intersects the rectifying and stripping operating lines.
ANSWER: optimal location of the feed to a distillation column [or feed stage; or height of the feed; accept descriptions of the location or height of the feed or input or entry stream to a distillation column; prompt on number of stages in the stripping section; prompt on number of stages in the rectifying section; reject “stages” or “number of stages”]
[10e] The [emphasize] total number of required stages is computed in the first step of the FUG method using the ratio in this property between the light and heavy keys. Vapor pressure quantifies this readiness of a liquid to vaporize.
ANSWER: volatility [or volatile; accept relative volatility]
[10m] The FUG and McCabe–Thiele (“thee-lee”) methods are derived by assuming that every component in the distillation obeys vapor–liquid equilibrium and this principle at every stage. The lever rule is derived from this fundamental principle of chemical engineering.
ANSWER: law of conservation of mass [or mass balance or mass conservation; or descriptions of mass being conserved; or conservation of moles or mole conservation; or material balance equation]
