In absorption, the absorbent is stripped to an extent that depends on its K-value. In stripping, the stripping agent is absorbed to an extent depending on its K-value. In Figure 6.1, it is seen that both absorption and stripping occur. Which occurs to the greatest extent in terms of kmol/h? Should the operation be called an absorber or a stripper? Why?
