APPLICATIONS FOR SULPHURIC ACID INDUSTRY
The production of sulfuric acid generates ash and dust, which sets as residue on the corrugated surface of the plate. Due to this, Plate heat exchangers are commonly used in the sulphuric acid production as they are easy to disassemble and clean with lower downtimes. Heat exchanger applications for Sulfuric Acid are mainly to cool the acid with a cold-water media during its various stages of production. The following production processes use heat exchangers either directly or indirectly for thermal heating or cooling.

Along with acid resistant and non-corrosive PHE gaskets and plates, PHE Sealing Solutions offers PTFE seals which are highly resistant to acid. These seals provide longevity to the gaskets. We also specialize in PTFE envelope gaskets which are applied mainly as a flange gasket in high chemical resistance applications.
Heat Recovery Applications -
Boiler Feed water Heating
Copper electrolyte heating
District heating
