Concept explainers
(a)
Interpretation:
The location in the column at which there will be greatest risk of liquid entrainment needs to be determined.
Concept introduction:
A distillation is a unit operation in which more volatile components are separated by using thermal energy to the column from top of the column and fewer volatile components are collected from the bottom of the column.
(b)
Interpretation:
The minimum column diameter needs to be determined.
Concept introduction:
A distillation is a unit operation in which more volatile components are separated by using thermal energy to the column from top of the column and fewer volatile components are collected from the bottom of the column.
The ideal gas equation is as follows:
Here,
(c)
Interpretation:
The vapor velocities at top and bottom of column needs to be determined.
Concept introduction:
A distillation is a unit operation in which more volatile components are separated by using thermal energy to the column from top of the column and fewer volatile components are collected from the bottom of the column.
The Mathematical Formula to calculate area is as follows:
The ideal gas equation is as follows:
Here,
(d)
Interpretation:
The increasing the pressure in the column would allow the vapor flowrate to be doubled.
