Abstract
In Brazil, the main technical solution found for the disposal of vinasse is fertigation, but there are restrictions of dosages in the crop. The generation of electricity using this thermal residue can reduce the costs of treatment and disposal of the vinasse in the environment. Thus, the main objective of this work is the study of the thermodynamic properties of the application of three different organic fluids in an ORC for the utilization of residual heat from the vinasse, as well as the gain of power inserted to the power generation in a traditional Rankine Cycle used in sugarcane power plants. The thermodynamic analysis was done in EES software with R290, R227ea and R124 fluids, and the results showed that all fluids presented a surplus of electricity produced (in kWh / TC), which, when combined with the conventional cogeneration systems, increase the total electricity produced in a sugarcane power plant.
