Insight into REFNOVA®
REFNOVA® involves a proven and scalable two-phase design:
- NOVAPRE
- SARP
Stage 1i. Feedstock Neutralisation
Particle size reduced feedstock is fed into a fluidisation vessel to neutralise alkali earth metals present
Stage 1ii. Drying
The neutralised feedstock is fed to a hot air dryer to remove excess moisture, before then being vacuum conveyed downstream
Stage 2i. SARP
Dried material is exposed to high temperatures; the lignin component of the feedstock is converted to, and extracted as NOACHAR, whilst its sugars are vaporised and fed to the condenser step
Stage 2ii. Condenser
Sugar vapours are passed through a water cooled condenser and liquified to a liquid sugar stream
Stage 2iii. Levoglucosan Hydrolysis
The liquid sugars are then fed into a vessel whereby it is hydrolysed and converted to NOVASUGARS
