Kaltenbach-Thiiring

The AZF pipe reactor process from La Grande Paroisse was combined with the fluidized dram granulator process from Kaltenbach-Thiiring S.A. The design melt concentration from the plant is 92% with 94% being achievable. The steam from the process is used to preheat the nitric acid feed and to vaporize the ammonia feed229.
