Separation Processes

Future biorefineries require cost-effective and efficient process technologies for the separation of compounds from process streams that can be refined into valuable biomass-based new materials, chemicals and fuels. Innventia has world-leading competence in this field, and can offer consulting work where different processes are studied either in our well-equipped laboratory or directly on location at mill sites.

 Examples:

  • The patented LignoBoost process for the extraction of lignin from black liquor
  • High-temperature membrane separation of e.g. hemicelluloses from process liquids
  • Leaching of inorganic and/or organic compounds from wood chips.
  • Separation of suberin and betulin from hardwood bark with a water-based method (patent pending).
  • Upgrading of hemicelluloses through precipitation and washing processes to high purities.

To give the whole picture, aspects on energy balances, further processing into chemicals and materials and mill system aspects can also be investigated.
