Abstract
Distribution of gas bubbles and volumetric mass transfer coefficient, Kla, in
a three phase system, with different types of solid particles at different
operation conditions were studied in this paper. The ranges of superficial
gas and liquid velocities used in this study were 0,03-0,09 m/s and 0-0,1
m/s, respectively. The three different types of solid particles were used as
a bed in the column (glass dp=3 mm, dp=6 mm; ceramic dp=6 mm). The
experiments were carried out in a 2D plexiglas column, 278 x 20,4 x 500 mm
and in a cylindrical plexiglas column, with a diameter of 64 mm and a hight
of 2000 mm. The Kla coefficient increased with gas and liquid velocities.
Results showed that the volumetric mass transfer coefficient has a higher
values in three phase system, with solid particles, compared with two phase
system. The particles properties (diameter and density) have a major impact
on oxygen mass transfer in three phase systems.
