The production of spherical ammonium dinitramide (ADN) particles (so called ADNPrills) is established at ICT as a batch process, using the emulsion crystallization technique. This paper presents how this know-how is transferred to the micro reaction technology. The goal was to develop a continuous working ADN-Periling process. The advantages of this continuous process for ADN are:
- Less thermal stress, as the ADN only remains for a very short time in the heating
- A more safety process, because there is only less amount of ADN in the heating
- The possibility to scale-up the process.
The conducted work has shown that it is possible to generate spherical ADN-particles with an adequate particle size by combining the micro reaction technique and the ADN emulsion crystallization process.
