2006 Meessen Stamicarbon Continuous emissions from urea plant finishing sections

A very interesting new development is the development of the Stamicarbon fluidized bed granulation technology. In this technology, a fundamentally different spraying technology is applied: Film spraying, surrounded by a high velocity hot air gas jet.

Sprayer and high velocity hot air gas jet are located in the bottom of a fluidized bed, which is kept in fluid state by the supply of cooling air through a fluidization plate.

Comparing the fundamental difference between this ‘film spraying’ concept with the ‘fine droplet spraying’ concepts, that are used in the classical granulation concepts can best be done by comparing the sequence of events in these processes. The quantity of urea formaldehyde can be reduced, without sacrificing product quality. There is no ammonia smell in the storage building.
