Abstract

The present work was developed, in the steam generation system of a canned tuna canning plant in Ecuador, in which an exergoeconomic and ecological efficiency analysis was applied in combination, with a view to identifying and quantifying the irreversibility’s existing in the process under study, and evaluate the environmental impact produced by the fuel used by this type of facility. The methodology used combined from the literature consulted, the analysis of conventional exergy and exergoeconomic with the ecological efficiency. The results obtained were: the greater destruction of exergy was caused by the steam boiler (with more than 98% of the whole system) for an exergy efficiency of 25.12%; the unit thermoeconomic cost of steam generated by the system is $ 28.07 / Gj; and the ecological efficiency of the steam generator of the industrial plant is 46.27%, with the use of fuel oil 6 as fuel and a thermal efficiency of 84.91%. These results show the need to increase the parameters of steam generation (pressure and temperature), as well as to evaluate the possibility of using other fuel alternatives, to improve the energetic and ecological effects of the tuna plant under study.
