3.9 Antifoam Control
Foam hinders the exchange of gas between the medium and the
gas phase in the head space. The exit gas filter can become
clogged with foam, which causes a pressure build-up in the vessel.
This can be prevented by adding antifoam agent.
The antifoam agent is kept in a reagent bottle that is connected to
the antifoam sensor and the antifoam pump via a hose. The sensor
also acts as a dosing needle. When the sensor comes in contact
with foam, the antifoam pump is activated and antifoam agent is
fed into the vessel via the dosing needle.
