Breakthrough Behavior of Fluids with Slightly Favorable Isotherms • A priori knowledge of velocity profiles is required in order to determine disper- sion coefficients for fluid flow through a packed bed. • Radial variations of concentration for constant pattern flow in a packed bed with a nearly linear isotherm are small compared to those in the axial direc- tion, making the cross-sectionally averaged concentration indiscernible from the solution to the plug-flow model. • The mixing-cup concentration moves slightly ahead of and behind what a simple plug-flow model predicts, and is based on the magnitude of the perturbation parameter in the velocity profile and the first order correction term. • Radial gradients of the fluid-phase concentration will form based on the shape of the velocity profile, which influence the breakthrough behavior at the bed outlet, causing nonuniform breakthrough to occur across the bed outlet. However, transverse dispersion attenuates this effect in comparison with the extent of the deviations from plug flow in the velocity profile. Dehydration of Gas Streams Using Shell and Tube Membrane Modules • The Nafion⃝R membrane remained intact and showed no degradation in integrity after being subjected to a pressure gradient of 133.3 kPa. • Tube-side feed streams are successfully dehydrated when a vacuum is applied to the shell side in lieu of a purge stream. • Relationships previously reported for the diffusion coefficient of water through Nafion⃝R membranes overestimate the transport of water through the membrane when a vacuum is used on the shell side due to decreased hydration levels of the membrane. 131
