Hi Eugene,
Regarding the term 'bubbler scrubber', I meant : the vessel(drum or sump) with a dip pipe & vent at its top, in which the gas stream with corrosive emmissions is introduced through the dip pipe (under the surface of used solution) & as a result, a clean gas stream only can leave through the vent, which can be directed to the top of structure.
I would appreciate your assistance.
Regards,
Ahmad S.
