Ammonium Nitrate Solution core equipment is the pipe reactor.
Its design has the following main advantages:
- Large operating range
- Easy maintenance
The short residence time in reaction zone makes also easier to control the feed ratio. The raw material ratio fine tuning is based on the pH of process steam leaving the separator. This gives a faster and more accurate measurement of transient excess of raw material.
To keep this control loop very fast, a special Casale sampling system can be provided with the proprietary equipment.
