Question
Transcribed Image Text:A distillation column is a process unit in which a feed mixture is separated by multiple partial
vaporizations and condensations to form two or more product streams. The overhead product is rich in
the most volatile components of the feed mixture (the ones that vaporize most readily), and the bottom
product stream is rich in the least volatile components. The following flowchart shows a distillation
column with two feed streams and three product streams:

b. Suppose values are given for mjand x2. Give a series of equations, each involving only a single
unknown, for the remaining variables. Circle the variable for which you would solve. (Once a
variable has been calculated in one of these equations, it may appear in subsequent equations
without being counted as an unknown.)
