Abstract
A tank cover made of a plurality of sections, which when connected, form a continuous tank cover enclosing the pickle tank. The tank cover is constructed of a plurality of exhaust sections each having an exhaust outlet and a plurality of sections having a plenum chamber which adjoin each other and the exhaust sections. The sections of the tank cover having the plenum chamber have an internal chamber for collecting evaporated acid fumes and transporting these fumes to exhaust outlets connected to the exhaust sections where the fumes may be discharged to an external scrubber.
