Resumen

In view of worldwide concern for the increase in energy consumption, as well as the application of viable alternatives that allow a better use of available energy sources, thermal waste has emerged as an energy alternative in industrial applications in which it is generated. In this sense, the present work analyses the energy potential of combustion gases emitted by a compression station, which can be used as heat source for a Rankine power cycle, which operates with different working fluids, including nine of organic type and the carbon dioxide (CO₂). The simulations demonstrated the capacity of the working fluids to increase the energy efficiency of the installation from the exhaust gases of the compression station, where toluene and CO₂stand out for presenting the highest efficiency levels, 21 and 20%, respectively. With the target of generating power, the results showed that refrigerant fluids considered in this analysis are not suitable at the temperature levels evaluated.
