The customer involved in this project is a manufacturer of Isocyanates/Polyurethane.
They required a stripping column with high corrosion resistance for a process utilizing sulfuric acid.
Due to the critical role, this column played in their application, performance and process guarantees
for the system were essential to ensure operational success and safety.
CHALLENGE
The column is intended to clean a mixture of sulfuric acid from organic components using steam as the stripping medium. Sulfuric acid is highly corrosive, and due to the high operating temperatures, many plastic corrosion-resistant materials could not be used. Exotic metals were deemed cost prohibitive by the client.
