Columns absorption, design

This section concerns the modelling of countercurrent flow, differential mass transfer applications, for both steady-state and non-steady-state design or simulation purposes. For simplicity, the treatment is restricted to the case of a single solute, transferring between two inert phases, as in the standard treatments of liquid-liquid extraction or gas absorption column design.

The absorption column design represents a compromise between mass transfer factors and economic considerations. The final design specification is for a column of 1.8 m diameter, approximately 32 m high, and containing 59 sieve trays.

In phase equilibrium, mole fraction in each of the phases is the most common way to express composition that goes along with mole balances around the system being studied. There is also the possibility to use mass fraction for defining composition. Mass balances around the system can then be made. For some situations, absorption column design, for example, the composition may be expressed as mass of solute per mass of solvent.
