Isocyanates are produced in highly acidic and corrosive environments at high temperatures.

Sulphuric acid is recovered for concentration during the toluene nitration stage. Bayonet heat exchangers installed in the evaporators are made from either tantalum or, sometimes, niobium.

The absorption of HCl gas during the phosgenation phase takes place in graphite columns.

With leading expertise in corrosion-resistant materials, Mersen, has the experience needed to manufacture equipment designed for this highly corrosive process.
Our references in this field demonstrate the efficiency of our equipment within strict safety standards.
