Your single source partner to
process bioproducts into ethanol.

Vinasses valorization

Principle

Vinasses concentration
INTERIS units are equipped with vinasses concentration device reducing the volume of vinasses of more than 80% by producing a stable residue which can be stored before the spreading.

Bio-digestion or vinasses drying
The biogas product can be burnt in boiler for producing steam, or for feeding a gas engine or gas turbine to generate electricity.  INTERIS holds an advanced technology to transform digested vinasses into solid product. The incineration of concentrated vinasses or the drying of methanized vinasses enables to produce some ethanol with “zero liquid effluent”.

Specifications
  • Applicable on raw vinasses and bio-digested vinasses.
  • Simple or multiple effects technology.
  • Co-current, counter-current or crossed current.
  • The design is independant or integrated to the distillation or dehydration.
Benefits
  • Low clogging.
  • Possible high concentrations adapted to the incineration thanks to the forced circulation.
  • Productive hours maximized.
  • Less stops for evaporators cleaning.
  • Low vapor consumption.
  • Energy couplings with the distillation and the dehydration.
