CORROSION RESISTANT EQUIPMENT FOR SULPHURIC ACID DILUTION AND CONCENTRATION
Acid dilution process
The concentrated acid and dilution water are mixed under pressure in a static mixer provided by an ARMYLOR® dilution tee pipe connected to the concentrated acid and dilution water feeds.
⇒ The dilution of acid in water generates considerable heat.
⇒ The hot corrosive mixture then flows through a corrosion-resistant heat exchanger of GRAPHILOR® impregnated graphite.
⇒ On the shell side, this heat exchanger is fed with cooling water which removes the heat and cools the diluted acid to the desired temperature.
⇒ Graphilor® 3 is the only impregnated graphite resulting from the combination between isostatic graphite and a specific resin.
⇒ Armylor® PTFE is Mersen material made from PTFE or PFA.
