Abstract
The absorber is a key component in a thermally-driven absorption system which significantly influences the whole system performance. The adiabatic spray absorption is one type of absorption process, in which the absorption fluid is dispersed into fine droplets having immense surface exposed to the vapor. In the current investigation, an improved analytical Newman model is presented which can consider the absorption heat effect. Using the model, the absorption characteristics of the adiabatic spray in aqueous lithium bromide solution is studied. The results show that the absorption heat significantly affects the absorption process. When the droplet radius decreases, the absorption rate can be improved and the maximum absorption time can be reduced. The current investigation can result in a better understanding of absorption mechanisms of the adiabatic spray absorption.
