Abstract
The development of economic activities, along with the evolution of society, has generated a growing demand for electricity, resulting in an increase in pollution from the exploration and use of fossil fuels. One possibility to overcome such environmental issues lies in the utilization of renewable energy sources employed with combined generation systems. This study presents an energetic, exergetic, and economic assessment of a proposed combined generation system for a sugarcane plant located in the state of Pernambuco, Brazil. The base system consists of a set of boilers that use sugarcane bagasse as fuel. The proposed scenario includes the boilers, with the addition of (a) an absorption cooling system that uses the water-ammonia chemical pair as a refrigerant, with a cooling capacity of 17 kW; (b) an organic Rankine cycle that uses n-octane as the working fluid, with an equivalent electricity production capacity of 1110 kW. The main results of the exergetic analysis showed an exergetic efficiency of 16.8% and 2.5% for the ORC and chiller, respectively. The economic evaluation revealed that the investment has an average payback period of 9.05 and 7.45 years for the ORC and chiller, respectively.
