Developing a computer code which solves concentration profiles simultaneously for vapor and liquid phases, we analyzed an effect of inner radius of wetted-wall column on separative performances of water distillation for H2O-HTO isotope separation. Results through the code were compared with experiments for H2O-HTO wetted-wall water distillation under the total reflux condition with columns of 3 and 8 mm of inner radius R. Total separation factors of R=3mm were larger than those of R=8mm, and the fact was well predicted by a numerical analysis. The total separation factors for theoretically maximum vaporization rate constant kv, A=1.57 × 104 cm/s gave a virtual its upper limit in the range of relatively large Reynolds number. © 1998 Taylor & Francis Group, LLC.

Simultaneous solution of concentration profiles in vapor-liquid phases of wetted-wall distillation column for H<sub>2</sub>O-HTO isotope separation

A simulation model was proposed for prediction of H2O-HTO separative performances of water distillation by a wetted-wall column. A wetted-wall column was assumed to be a circular tube, and mole-fraction profiles in the tube were obtained by coupling the equations which describe diffusion processes of both vapor and liquid phases and by solving the equations simultaneously. It was found that the calculations for constant mole-fraction boundary with high mass-transfer rate resulted in overestimations of degree of separation. The relative difference of the HETP value for constant mole-fraction boundary from that for the present model was −19% when P = 101.3kPa, T = 373K, R = 0.8 cm, H = 100 cm, k v, A = 1.0 × 104 cm/s and Rev = 660. © 1998 Taylor and Francis Group, LTD.
