Longitudinal mixing in gas-sparged tubular vessels

Abstract

The degree of longitudinal mixing in gas-sparged vessels has received scant attention, other than the observation that such vessels appear “well mixed.” For reactor design, particularly where it is desired to drive a reaction essentially to completion, the departure from plug flow can be very important. Even when complete mixing is desired for a proposed commercial vessel, a knowledge of mixing encountered in pilot plant equipment is needed for proper scale-up. Mixing studies for water in vessels of various sizes are reported in the form of longitudinal dispersion coefficients. © 1965, American Chemical Society. All rights reserved.
