3.1. Experimental data
Three different beats are taken by ever-changing the volume flow of wash agent. Here water is the washing agent fed from top in to the absorption column. MA is the value of the concentration of the acetone vapour at the outlet. It is metrical with the help of a Flame Ionisation Detector (FDI).

3.2. Calculation equations
It is assumed that the molar push-down stack of the pure air and water remains the same in the inlet and in outlet.
