Uhde offers its competence and experience for customers ranging from process studies up to the execution of projects on an EPC basis.
State-of-the-art technology for the production of low density ammonium nitrate (LDAN) and chemical pure ammonium nitrate (CPAN) can be provided.
Uhde has designed LDAN prilling plants operating up to a capacity of 1,200 mtpd in a single line. Today, Uhde is the leading licensor for the LDAN prilling process.
Low-density ammonium nitrate (LDAN) is used as an effective and cost-efficient mining explosive, mainly in a mixture with fuel oil (ANFO) or in emulsion-type explosives.
For the production of LDAN prills, the AN melt from the AN neutralization is concentrated, pumped to the top of the prilling tower and mixed with a prilling additive . From here the melt is sprayed (fine droplets) into the prill tower and crystallizes in a countercurrent stream of cool air.
The Uhde® LDAN prilling process is known for:
low air and steam consumptionby re-use of cooling air
the air used in the process is scrubbed to meet BAT (best available technology) emission levels
flexibility: LDAN and CPAN can be produced in the same plant
The above processes are referenced and well proven.
