Dynamic tests were made on several industrial agitated pulp chests to quantify the extent of non-ideal flow (bypassing, recirculation, and dead zones) and the disturbance attenuation achieved. Most chests showed a significant reduction in disturbance attenuation compared with an ideally mixed chest. The importance of correctly locating the pulp fee and exit locations was confirmed. The power calculated for agitation of pulp chests, based on existing design criteria, did not completely eliminate non-ideal flow in the vessel. Additional power is needed to approach an ideal dynamic response.
