MODELING OF ADSORPTIVE DRYING OF N-PROPANOL

摘要：

On the basis of experimental work connected with mathematical modeling, a parameter analysis was made for the adsorptive drying of water-miscible organic liquids.The experimental work involved n-propanol dehydration using two desiccants, 3A and 4A zeolite molecular sieves.Equilibrium relationship and fixed bed breakthrough curves were determined experimentally.The parameters required by the model are equilibrium constants, liquid film mass transfer coefficients, intraparticle diffusion coefficients, and axial diffusivities.A linear driving force (LDF) relation was applied to represent the mass transfer rate in the particle liquid film and inside the adsorbent particle.The fit of the model to experimental breakthrough data was quite good.
