3.3. Effect of gas flow rate on the percentage of removal efficiency
In Figs. 5 and 6(a, b, . . .), the removal efficiency is presented as a function of inlet air flow rate. Each curve in these figures has been obtained in a fixed water (physical absorber) flow rate. In addi- tion, each figure corresponds to a single particle size. Increasing of the inlet air flow rate, results in shorter residence time in the scrubber. Consequently the removal efficiency will be decreased by decreasing in the residence time of the particles. In Fig. 5a–d, for particles ranging from 4 to 20
