Process equipment for the Phosphoric acid - H3PO4
Phosphoric acid (H3PO4) is mainly use in the production of fertilizers. Mersen provides corrosion-resistant process equipment which are part of the pre-treatment (concentration) and post-treatment (defluoration) of the wet phosphoric acid production.
Phosphoric Acid Concentration - pre-treatment
The graphite shell and tubes heat exchangers are key components of the concentration of the wet phosphoric acid. Mersen has provided the largest units for the biggest green field phosphoric acid projects in the world.
A part from S&T technology, Mersen has a long experience on concentration units running with Polybloc® graphite block heat exchangers.
6 meters length tubes without any joint
Mersen six meters length tubes without any joint Polytube® is extremely resistant, deliver longer periods between maintenance than other exchangers on the market with joint assembly.
Increase abrasion resistance & lifetime
Rigilor® is a coating applied on large graphite blocs or tube sheets to increase the mechanical and the abrasion resistances.
Focus on :
Mersen Brazil recently assembled the largest graphite shell and tubes heat exchanger for the Latin American market. This 64" x 24" graphite evaporator is part of the phosphoric acid process. Mersen is the only one to manufacture 6-metre-long graphite tubes without joints
Phosphoric acid defluoration - Post-treatment after purification
Mersen Graphilor® columns are manufactured with Graphilor®, the exclusive impregnated graphite developed by Mersen to cope with the corrosion environment.
Armylor® PTFE Columns
Armylor® PTFE loose lined columns combine the corrosion resistance of the PTFE and the safety of the seamless lining process together with the mechanical resistance of the steel shell.
Sulfuric acid process
Mersen provides gas-gas shell and tubes heat exchangers in nickel alloys.
Mersen manufactures metallic heat exchanger such as Economiser shell and tubes heat exchangers.
