The Vinasses valorisation process is one of numerous solutions proposed by INTERIS.

Vinasses are effluents with a strong organic charge that need a mandatory treatment depending on the fermented raw material.

Vinasses concentration

INTERIS units are equipped with vinasses concentration devices reducing the volume of vinasses of more than 80% by producing a stable residue which can be stored before the spreading.  Its transportation costs gets more economical for spreading.

Bio-digestion or vinasses drying

An alternative is to conduct anaerobic digestion.   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 sugar cane vinasses into solid product, that can be used to produce powder fertilizers.

The incineration of concentrated vinasses or the drying of methanized vinasses enables to produce some ethanol with “zero liquid effluent”.

• 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.

• 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.
