The emulsion consists of freshly produced soap, oil, alkali, water etc. In such environment the reagents continue to saponify without any additional supply of energy.
In a conventional saponification process the initial reaction is slow, while with the JET such stage is immediately completed and the saponification easily reaches its linear reaction phase.
In a conventional saponification plant the use of a two concentrated caustic soda solution (i.e. 50% NaOH) brings to a non-homogeneous soap mass. Furthermore such soap tends to be highly viscous and cannot be easily pumped in continuous reactors based on high recirculation processes. These facts determine a lower limit of water content into the neat soap.
In a JET saponification, this lower limit can be sensibly reduced thanks to the formation of a stable emulsion in a very small volume.
Simultaneously to the supply of the reagents, the JET receives a small flow of steam of which, flow and pressure, can be fine tuned for the formation of the best emulsion.
