Energy potential of vinasse derived from rum manufacturing

Abstract

The purpose of this study is to analyse the energetic potential of the vinasse coming from the distillation of rum. 10 to 15 l of vinasse are obtained for each unit of alcohol. This is being used as fertilizer for the cultivation of sugar cane. Three samples are analysed for physical, chemical and fuel properties: raw vinasse, its distillate and residue. The results demonstrated that raw vinasse can be used as an additive to liquid fuels with a calorific value of approximately 792 kJ/kg and a boiling point above that of flammability, which flavours the non-formation of vapours. The amount of solid waste present could be detrimental to atomization inside furnaces or its flow through combustion chambers, so it must be pre-treated.
