Distillation

Principle

Distillation is part of the procedures and solutions developed by INTERIS. In fact, new distillation technologies consist in energy coupling with multiple effects or by integrating thermo-ejectors or by mechanical steam recompression.
INTERIS technology is also based on the use of an additional column enabling to decrease the wash quantity increasing the necessary steam quantity.

Specifications
  • Installed capacities from 82 000 l/d to 950 000 l/d.
  • Vacuum or pressure running of the columns.
  • Small footprint.  Stripping part and rectifying part integrated : Raw Alcohol production at high yield 93% vol.
  • Multiple extractions possibilities to get the expected quality.
  • Independent or superposed columns according to the chosen scheme and climatic conditions (wind and earthquake).
Benefits
  • Low pressure steam : optimal use of the turbines in congeneration units.
  • Distillation at low temperature : decrease clogging and cleaning frequency and production time is maximized.
  • Self-supporting columns : only 2 framing levels needed.
  • Specific schemes for use of high pressure steam with “CHACOUX”, multi-nozzle thermos-ejectors, INTERIS design.
  • Integrating of trays / structured packing of last generation : enhanced unit performances.
  • Energy coupling with dehydration units, spent wash or stillage concentration and drying units.
  • Lower spent wash or stillage quantities to be treated : energy savings and steam consumption decrease.
