Vapour Gas Mass Transfer Absorber
It is generally believed that the vapour absorption systems must be “air tight”, especially systems with sub-atmospheric working pressures, e.g. LiBr/H2O systems where air entrainment is a risk and the performance is seriously affected by the inward leakage. The earliest report on the effects of non-absorbable gases on the absorption process is probably that of Haselden and Malaty. They reported that the presence of air in small volumetric concentrations greatly reduced heat and mass transfer rates in the absorber of an aqua/ammonia system. Later, Burdukov et al. conducted experimental work on water vapour absorption by a thin film of an ...
