Key features

Our distillation-membrane hybrid process system with heat integration for bioethanol rectification and dehydration offers you low life-cycle costs and a short payback time. Sulzer has extensive experience in the following fields: 

  • Mash / beer column (heavy fouling applications) and rectifier for bioethanol distillation process 
  • Dehydration of bioethanol by pervaporation / vapor permeation, heat integrated with the overall process 
  • Membrane filtration (MF/UF/NF) before fermentation 
  • Liquid-liquid extraction for strong acid hydrolysis route 
  • Biodiesel: fatty acid methyl ester (FAME) drying, methanol recovery, glycerine drying, glycerine purification 
  • Free fatty acid removal from edible oil 
  • Distillation, crystallization and film evaporation technologies for biorefining processes, including production and purification of lactic and succinic acid
