2nd Generation Ethanol
Cellulose Pretreatment for the Transformation of Biomass Energy
Process heating requirements for cellulose ethanol pretreatment applications are more demanding compared to grain-based ethanol production. These demanding pretreatment methods typically involve a wide range of difficult processing conditions high temperature rises, rapid heat transfer, high pressures and low pH leading to requirements of specialty metals.
In addition, a wide variety of fibrous biomass feedstock material is utilized including:
Solaris® direct steam heaters are uniquely positioned to address the process heating requirements for cellulose ethanol applications. These steam heaters play a key role in biological pretreatment processes of renewable energy by sufficiently hydrolyzing and opening up the structure of lignin-based biomass feedstock to allow efficient and effective enzyme hydrolysis of the hemicellulosic sugars.
Solaris heaters by Hydro-Thermal, with a straight-through process design, utilizing high velocity steam, are ideal for thick slurries and high fiber content common to a wide range of biomass feedstock. Depending on the pretreatment process, Solaris can be designed and constructed around specific process conditions while maintaining key advantages:
- No plugging or fouling
- Large temperature rise
- Near-instantaneous heat transfer
- Precise temperature control
- Process stability
From pilot lab research projects to full-scale commercial plant operations, there is a full range of Solaris heaters for all applications.
