Data on liquid phase‐controlled gas absorption in the loading regime are presented. Carbon dioxide was desorbed from water by using a 6‐in. Diameter tower and 1/2‐ and 3/4‐in. Ceramic rings. Below the loading point, H L increases approximately as the 0.25 power of the liquid rate and is independent of gas rate. In the loading regime, however, it was found that at high gas rates H L increases less rapidly and may even decrease with increase in liquid rate. At intermediate gas rates, the effect of liquid rate on H L is intermediate. These effects are explained on the basis of the interaction of the gas and liquid flow rates and the effect of this interaction on K L and a . The results suggest that in some cases tower capacity may be increased without increasing H L .
