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.
Mersen offers a range of three Graphilor® 3, based on various impregnants (phenolic, carbon and PTFE) which ensure the imperviousness , the resistance to corrosion and temperature as well as the long-term stability.
⇒ Armylor® PTFE is Mersen material made from PTFE or PFA.
Our expertise is the mastering of all PTFE manufacturing processes, such as paste extrusion process, isostatic molding and PFA transfer molding.
