Steady-State Gas Absorption with Heat Effects

1 Steady-State Gas Absorption with Heat Effects 

Subscripts L and G refer to the liquid and gas phases respectively, and subscripts in and out refer to the inlet and outlet streams. 

Mole ratio and mole fraction contents are related by 

In the steady-state design application, the flow rates and Gm, and concentrations Yjn, Xjn, Yout Xout will either be specified or established by an overall, steady-state solute balance, where 

Temperatures Tl in and Tq in will also be known. The problem then consists of determining the height of packing required to obtain the above separation.

In this section, the equations are presented for the common types of contactors differential contactors and stage-wise contactors. The equations are developed for the case of steady-state, countercurrent contacting of liquid and gas with negligible heat effects, with a single-component absorption. Some discussion of extensions to other situations follows.
