Resumo
This work has been performed using the fourth-generation-like industrial computed tomography
developed at the IPEN, constituted with 70 NaI(Tl) 25:4 mm 50:8 mm (diameter
length) and a bubble column for industrial process was evaluated. The column is a Perspex
glass cylindrical tube of 80 mm internal diameter, 100 mm external diameter and 1400 mm
height constituted the following parts: liquid circuit (water), a gas circuit (4 `{min) bubbled
into a system containing two limiting holes of 4 mm and 2 mm, located at 65 mm from the
centre of the column each one in opposite side.
-ray tomography experiments were carried
out, using this simulator column both empty and filled with water plus gas bubbling. In this
work the scanner was set for 5 views and 14 projections each. The resulting images describe
the liquid or gas phase holdup distributions for bubbles generated in a hole of 4 mm and
2 mm diameters located at 15 mm of the column wall in a opposite side, respectively. It
was established that the newly developed fourth-generation-like fan-beam arrangement
-scanner unit has a good temporal resolution acceptable given the size of the column used
in this study and capable to infer the relative proportional of gas and liquid proportion in
the column.
