Non-absorbable gas effect on the wavy film absorption process

Evaluation of mass absorption in LiBr flat-fan sheets

“…Another possible strategy for reducing absorber size is to in-crease interface efficiency by inducing mixing. Since convection mechanisms are known to be more efficient than diffusion in transport processes [15], Kang et al [16,17] proposed generating Marangoni recirculation by adding specific surfactants to induce mixing in the liquid solution. Nevertheless, an effort has been done to get a fully understanding of the way these additives increase the rate of the transfer processes [18][19][20].…”

Numerical and experimental study of absorption of H2O vapor in wavy falling film of LiBr aqueous solution in vertical tubes and in presence of non-absorbables

“…The authors reported that a value of only 0,01 % reduces 65 % the rates of heat and mass transfer. In a latter work, Yang and Jou (1998), the authors improve their predictions of the mass transfer rates. However, their model overpredicts mass transfer rates at low non-absorbables concentrations and still underpredicts mass tranfer rates at high non-absorbables concentrations.…”

Effect of the Flow Rate of Water Dropping onto the Evaporator in an Absorption Chiller

“…An absorption chiller attracts attention of many researchers working on saving energy because it can utilize exhausted heat and has no ozone depletion and no global warming potentials. However, it has some problems such as low coefficient of performance, long boot-time, the performance depression due to non-absorbable gas 1) and so on.…”
