with an axial fan which is rotated by an electromotor. This rotation
provides a suitable mixing and a high contact surface between gas
and liquid phases with creation of small droplets. In addition to
this, the rotation makes a sufficient suction in inlet stream. Therefore
there is no need air blower in this setup. The entrance pipe of
scrubber, with 0.13m internal diameter, was located in the atmosphere
of the screening section of the PVC production unit. So the
air of the screening room (containing PVC particles) was conducted
to the scrubber via this pipe.
