TYPE OF EQUIPMENT:
Stripping tower.
OPERATION PRINCIPAL:
Volatile compound stripping tower and treatment
of stripped compound with ecochimica scrubber.
The stripping tower is used to reduce the volatile compound
concentration (ammonia for example) in a fluid (waste water
and process water).
In the ecochimica® stripping tower the fluid to be treated is
pushed at the top of the tower and sprinkled downwards by
spray-nozzle through special filling packs, which are inserted
in the tower to increase air/fluid contact area and where a
counter-current air flow is conveyed by proper ventilator.
In this phase the compound is transferred from the fluid to
the air. Exhaust air from the stripping tower is conveyed to
a chemical scrubber to reduce pollutant concentration to be
released into the atmosphere within environmental law limits.
The correct plant dimension is closely related to the fluid flow
rate and to the in/out compound concentration.
It is possible use hot air to increase stripping efficiency to
reduce plant dimension and cost.
