Chapter 10
Staged and Packed Column Design
In previous chapters, we learned how to determine the number of equilibrium stages and separation in distillation columns. In the first part of this chapter, we discuss details of staged column design such as tray geometry, determination of column efficiency, calculation of column diameter, downcomer sizing, and tray layout. We start with a qualitative description of column internals and proceed to a quantitative description of efficiency prediction, determination of column diameter, sieve tray design, and valve tray design. In the second part (Sections 10.6 to 10.10), we discuss packed column design including selection of packing and determination of column length and diameter. New engineers are expected ...
