Question

5. Absorption Separation: What are the key important parameters for design and operations of Absorption Separation Processes using solvents?

Answer 1

The two key design and operating parameters in separation processes are

-efficiency,

which indicates how well components are separated, and capacity, which is related to

the hydrodynamics of the contacting device and the overall rate at which the desired

material can be processed without loss of efficiency.

-Column height is determined by

the efficiency of the separation process, while the diameter of the column is governed

by the required capacity.

Phase equilibria, mass balances and design parameters are required for the reliable design of a separation process and these topics will be
considered briefly.
