Investigations on the influence of the velocity (flow) of gas on the surface integrity of the layer of adsorbent “mercerized wood” were carried out, the data on the aerodynamic resistance of the layer depending on the specific consumption of the air and value of the residual pressure of gases above dried adsorbent were obtained. At density of the adsorbent within 0.25 to 0.35 g cm−3 the consumption of gas can vary up to the value of 1.4 l cm−3 min−1. It is shown that the aerodynamic resistance of the layer is insignificant at the density of the layer of the adsorbent no more than 0.35 g cm−3. Functional dependences of aerodynamic resistance on the specific consumption of gas for different densities of the layer of the adsorbent were obtained. The empirical equation of Shilov-Dubinin for calculation of the process of absorption of HF is illustrated.
