A seismic vision regarding a methodology to estimate globally the energy-ecologic efficiency of thermopower plants (TPPs)

This paper discussed the possibility of replacing the internal combustion engine of the series plug-in hybrid electric vehicle (PHEV) powered by gasoline A and Brazilian gasoline in single-fuel mode by one fuelled with 50% bioethanol and 50% biogas in dual-fuel mode. The simulation of the combustion of the fuels selected, such as bioethanol, biogas and gasoline A, were carried out through GASEQ software to calculate the energy-ecological efficiency of the single-fuel and dual-fuel modes. The well-to-pump (WTP) emissions of the bioethanol and biogas production from sugarcane were evaluated through GREET software. The tank-to-wheel (TTW) emissions were determined to each series PHEV operating modes. Thus, the well-to-wheel (WTW) emissions were calculated through the sum of the WTP, TTW and electricity mix emissions. According to the results, the energy-ecological efficiency for the dual-fuel mode was 10.7% and 24.1% higher than that found for the single-fuel mode powered by gasoline and Brazilian gasoline, respectively. The analysis showed that the losses during the biogas production aggravate linearly the WTP emissions, and consequently the WTW emissions of the series PHEV. Besides that, the dual-fuel mode presented 15.5% and 12.8 less TTW emissions than the single-fuel mode powered by gasoline A and Brazilian gasoline, respectively. Comparing to the emission standards, the dual-fuel mode presented TTW emissions 30.5% higher than the European Union emission standard by 2021. Although the dual-fuel mode does not meet none of the emission standards, this engine mode can be an alternative to at least reduce the tailpipe emissions.

“…The following Table 8 shows the estimated mass in tones of pollutant gases, which are issued annually by the thermoelectric plant investigated in steady state that operates 7200h per year. Cardu and Baica (1999) analyzed the environmental impact of emissions from gas-fired combined cycle, in other words, associations of plants with gas turbines with steam turbines operating in cogeneration system and using fuels: coal, oil and diesel natural gas. In this analysis, we consider emissions of carbon dioxide, nitrogen oxides and sulfur dioxide; furthermore, a comparison of concentrations of each compound of the exhaust gases with specific regulatory standards.…”

“…Ecological efficiency (ε) is a dimensionless indicator to assess the environmental impact of exhaust emissions from a thermal power plant, by comparing emissions of pollutants integrated hypothetically (equivalent CO 2 ) with existing standards of air quality. It is considered the conversion efficiency as a determining factor on the specific, express emissions by a fractional number (Cardu and Baica, 2001). Pollution indicator by (Cardu and Baica, 1999;Villela and Silveira, 2006) and ecological efficiency by (Cardu and Baica, 2001;Villela and Silveira, 2007) are defined by the Equations 17 and 18.…”

The purpose of this article is to through the analysis of the first law of thermodynamic for a combined cycle determines the ecological coefficient of the same. This system consists of two gas turbines, two heat recovery boilers and a steam turbine, having a total installed capacity of power generation of 500 MW. This plant will be installed in a small town located 180 km from São Paulo. This place was chosen based on technical aspects by present proximity to the pipeline and transmission line, water availability and other favorable environmental aspects of the project. The natural gas that will serve as the plant's fuel will come from the Field of Mexilhão, from the base of Caraguatatuba, and the water used for cooling will come from the Paraíba do Sul River.
