A new type of absorber

helical rotating absorber

has been developed. This kind of absorber is different from other rotating ones

with the advantages of simple structure and high mass - transfer efficiency. Experimental results showed that the interfacial surface area per volume of the absorber a was 20 times higher than that of the B - 25 whirlflow tower plates

and its liquid-side mass -transfer coefficient kL is about 0. 08 cm/s. The thickness of the liquid film is thinner than that of gravity flow. The higher the rotating velocity

the higher the a and kL
