Abstract
Due the low complexity the Organic Rankine Cycle (ORC) can be considered one of the best options for the waste heat recovery at a low and medium temperatures. A technical and economic study was conduct in this work, in order to increase the efficiency in the electricity production and, thus, reduce fuel consumption and polluting gas emissions in an Internal Combustion Engine (ICE). To do this, a set of ORC have been suggested, it plant contains: an evaporator, a pump, a superheater and a condenser with the water supply made by the urban net of water. The simulation occurred on software HYSYS version 8.6 of ASPENtech®, the simulated system is able to increase the electricity production in almost 20% and the First Law efficiency of the ORC plant in almost 6%, when the working fluid was toluene. The economic analysis, based on CEPCI (Engineering Chemical Cost Plant Index) model, showed the financial return of the ORC system implementation may occur in six years. With this, it is noted the ORC system, sespite being an appropriate technological solution to recover the waste heat present in ICE’s exhaust gas, it still needs incentives from government for a wide application of the system, which financially support the investor.
