Comparison with Vacuum Distillation

Currently, the only alternative commercially-available full scale technology for biodiesel and saponification-derived glycerol purification to EET's process is vacuum distillation. However, EET's process has several competitive advantages over distillation technologies as indicated below.

Vacuum Distillation EET Process
  • Well established technology for glycerin
  • Low recovery/yield
  • High capital cost
  • Energy intensive
  • Only suited to operations >30 tons/day
  • High maintenance
  • Sensitive to feed stream variations
  • Production proven technology for glycerols/glycols
  • 95%+ recovery
  • Lower capital cost
  • Low energy use
  • Scalable process
  • Low maintenance
  • Tolerates feed stream variations
