Luiza Esteves considers the design, cost, and reliability of
corrosion-resistant alloys for use in the phosphoric acid industry.
The corrosiveness of phosphoric acid during the wet process concentration will depend on the source of the phosphate rock and the presence of impurities. In this article, a detailed comparison between graphite and metallic tubes in the heat exchangers used in evaporators and their advantages in terms of design, cost, and reliability will be provided.
