ABSORBERS IN THE OPEN ABSORPTION SYSTEM

This paper describes an experimental study of four different absorber designs in this type of system: cross-current and counter-current pack ed-bed absorbers, the spray absorber and fluid-bed absorber. In a labo ratory pilot, plant, working lines for the absorbers were determined u nder adiabatic conditions. The influences of internal solution flow, g as flow, pressure drop and dissipation are discussed. The working line s represent the efficiency for each absorber. The highest performance occurs with the packed-bed absorbers, followed by the fluid-bed absorb er and finally the spray absorber. For open absorption systems in air- conditioning applications (small scale), the cross-current absorber is preferable, and for industrial utilization (large scale) the fluid-be d absorber should be chosen.
