The two major types of airlift contactors, concentric-tube and external-loop, were investigated for their gas holdup (riser and downcomer) and overall mass transfer characteristics. Results obtained in batch charges of tap water and 0.15 kmol/m(3) NaCl solution are reported for external-loop airlift contactors having downcomer-to-riser cross-sectional area ratios, A(d)/A(r), ranging from 0.11 <or= A(d)/A(r) <or= 0.69 and for concentric-tube types in the range 0.13 <or= A(d)/A(r) <or= 0.56.The… CONTINUE READING
