Wave Front Behavior in Adsorption Reactors
Publication: Journal of Environmental Engineering
Volume 118, Issue 4
Abstract
This paper describes computer modeling experiments for single adsorbate flow through a packed‐bed adsorption reactor to examine the behavior of concentration “wave fronts” for aqueous and solid phases. Conclusions were: (1) The shape of the wave front assumes a steady‐state shape after development; (2) the wave front has constant velocity; (3) the solid‐phase wave front is synoptic with the aqueous‐phase wave front; (4) the wave‐front velocity can be predicted from isotherm data; and (5) the adsorbate‐concentration breakthrough curve can be calculated from wave‐front data. These conclusions relate directly to design and operation. First, the length of the reactor can be calculated by wave‐front velocity, which can be determined from isotherm data. Second, for pilot plant studies the major interest includes wave‐front shape, length, and velocity. Third, in operation, the progress of the wave front should be monitored to predict the breakthrough curve.
