SIMULTANEOUS ABSORPTION AND/OR DESORPTION OF HYDROGEN SULPHIDE AND AMMONIA

[摘要] References(11)Cited-By(1)Experiments on simultaneous absorption of H2S and NH3 in water, absorption of H2S in aqueous solutions of NH3 with simultaneous desorption of NH3, and simultaneous desorption of H2S and NH3 from aqueous solutions of NH3 and NH4HS were carried out using a continuous stirred-cell absorber. Absorption and desorption rates were analyzed on the basis of a theory of diffusion with instantaneous reversible chemical reaction. It was confirmed that the theory could be commonly applied to each case in the experiments, and gives a satisfactory interpretation of the effects of experimental conditions on the absorption as well as the desorption rate.
