As the alloys most resistant to acid corrosion are not frequently resistant to high
temperature attack , it is common practice to line the top and bottom portions of
distillation towers with different materials to obtain the most favourable
performance ...

Despite provision for drainage at the bottom of the large tanks , the unevenness
of the bottom plate ensures the presence of water causing corrosion . The bottom
of the tank is generally cement lined , which is supplemented with cathodic ...
