Urea

Urea producers can reduce consumption and/or increase production of their plants by introducing the various revamping technologies developed by an independent company like Casale. In addition, they can upgrade single sections of their plants and have them operating more efficiently using Casale special equipment designs and specific technologies for unit operations.

At the beginning of the 90’s, Casale started its activity in urea plant revamping first focusing on the synthesis reactor, extending it then to entire process and to all its major components.
With the innovative technologies developed since then, Casale is in a position to revamp any kind of urea plant in the most efficient way.

With more than 100 revamping projects successfully carried out in the last decades, Casale is now the world leader in plant revamping and its technologies are installed in many urea plants all over the world.
