Plate falling film absorber with a film - inverting configuration is a new kind of absorber that combines the plate falling film absorption technique and the film - inverting technique. In this study

the absorber's structure under design condition was determined by building and solving mathematical model of the plate falling film absorption process with film inverting configuration. The heat and mass transfer performances were calculated by the model under different solution flow rates

its inlet concentrations

its inlet temperatures

absorption pressures

and cooling conditions. Then the comparisons were performed between the new designed film - inverting absorber and the designed vertical plate falling film absorber.
