CONTROLLING ROOF CORROSION IN PHOSPHORIC ACID ATTACK TANKS USING ANCHORED THERMOPLASTIC LINERS

摘要

Phosphoric acid attack tank floors and walls have historically been lined with acid resistant brick and membrane systems. While such linings have become industry standard, there is less consensus regarding the best way to line the ceilings of these tanks. Numerous liquid applied linings have been used with variable success and service life. When properly selected and installed, anchored thermoplastic liner systems effectively protect the ceilings of phosphoric acid attack tanks against corrosion in different service environments.
