Resumen:
Bioethanol and bioelectricity production from crushing sweet sorghum in a sugarcane factoryG De Boeck and D PazAbstract. Looking to replace fossil fuels, several renewable alternatives are currently being studied to meet global energy needs. Bioenergy crops that stand out as the main immediate renewable alternatives for the production of liquid biofuels and bioelectricity are sugarcane and sweet sorghum, each of which has a high energy return rate. This paper uses simulations to analyze the feasibility of the industrialization of sweet sorghum in a sugarcane mill for the production of bioethanol and electric energy. The raw material is Argensil 165 Bio, a cultivar of sweet sorghum studied by the EEAOC that can reach values of 13.3% of total fermentable sugars (TFS) in their stalks with a 11.7% fiber content. The mass balance simulator shows that the ethanol produced using sweet sorghum syrup is 65.5 L/t of crushed sorghum and the sorghum bagasse generated is 26.9% at 52% moisture. The energy balance simulator shows that the bagasse burnt in the biomass boilers can produce enough steam for mechanical, thermal and electric energy generation. Total electric energy generated is 20.7kWh/t of crushed sorghum without any changes in process parameters or equipment. By replacing steam turbines with electric motors, it is possible to achieve electrical generation of up to 61.0kWh/t of crushed sorghum. The global simulation, mass and energy balance simulations confirm that sweet sorghum can be easily used in sugar industries before sugarcane season for bioethanol and bioelectricity generation.Key words Sweet sorghum, bioethanol, bioelectricity
