“…First, they do not exhibit any extreme flash point behavior and we may update lines B and D in Table 3. Second, the pure component p-xylene and m-xylene FP measurements in the literature [10] (Table 1) For the mixtures acetic acid þ 1-pentanol and acetic acid þ cyclohexanone, the UNIFAC Dortmund 93 model fails to predict the non-extremum flash point behavior. Indeed, it predicts a strong positive deviation from ideal behavior for both mixtures, while the experimental data in Moghaddam et al, 2012 [38] indicates a negative deviation.…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. This is an author-deposited version published in : http://oatao. b s t r a c tThe flash point temperature and the boiling temperature of a mixture are related by the fact that both can be modeled based on vapor-liquid equilibrium (VLE) of each component. It has been suggested in the literature that there might exist a concomitance between azeotropic behavior and minimum/maximum flash point temperature for binary mixtures. In order to verify this statement, we derive new temperature dependent functions that relate the conditions valid for azeotropic behavior and those valid for minimum/maximum flash point behavior. Analysis of experimental data and predicted results allowed us to propose a heuristic to forecast extremum flash point based on the sole knowledge of azeotropic data and boiling and flash point temperatures differences. Extremum flash point might occur when both components are flammable and when the gap between the flash point temperatures of individual components (DT fp ) is of the same order or smaller than the boiling temperature gap (DT b ). Hence, we contribute to the assessment of the fire and explosion hazards in binary mixtures eventually presenting a minimum flash point behavior.

“…Most of the important fuel properties, such as density, kinematic viscosity (Alptekin and Canakci, 2008Canakci, , 2009, oxidation stability (Jain and Sharma, 2011), flash point (Kim and Lee, 2010;Alptekin and Canakci, 2009), calorific value, and cetane number (Benjumea et al, 2008) vary linearly in multiple biodiesel blends. Hence, the linear relationship among the fuel properties was considered to determine the optimum blending ratio.…”

Biodiesel can be used effectively as engine fuel despite several limitations in its fuel properties. A set of experiment was conducted to improve fuel properties by blending palm biodiesel (PB) with coconut biodiesel (CB) and jatropha biodiesel (JB). MATLAB optimization tool was used to identify the optimum blend ratio for good fuel properties. A linear relationship among fuel properties was considered for MATLAB coding. The resulting optimum blend ratio and the equations of the MATLAB code were used to predict the fuel property values and were compared with the experimental values of the optimum blend fuel properties. Two new biodiesel blends were developed, namely, the optimum blends of palmcoconut (PC) biodiesels and jatropha-palm-coconut (JPC) biodiesels. Both biodiesels demonstrated overall improved fuel properties compared with those of the individual biodiesels presented in the blends. Engine performance and emission were tested using 20% blend of each biodiesel (JB, PB, CB, PC, and JPC) with petroleum diesel (OD). The engine performance and emission characteristics for the PC and JPC blends were then compared with those of OD. The average engine power for the blend of 20% JPC biodiesel and 80% OD (JPC20) was maximum at lower fuel consumption than the blend of 20% PC biodiesel A C C E P T E D ACCEPTED MANUSCRIPT 2 and 80% OD (PC20) at full load condition. The emission characteristics of JPC20 were also comparable to or lower than those of OD, except for HC. However, when both engine performance and emission were considered, JPC20 was found to be the best fuel compared with OD and other fuel blends.

“…The previous studies on fuel flash point focussed mainly on some specific low pressure points, and the samples consisted of an almost pure substance. The analysis of the flash point was found to be more dependent on the empirical correlations, lacking sufficient theoretical analysis.…”

Summary To study the low pressure influence on the flash point and fire hazard of organic fuels and their aqueous solutions, a series of experiments has been conducted to measure the open‐cup and closed‐cup flash points of methanol, ethanol, and n‐decane aqueous solutions including different mole fractions under different static pressures ranging from 35 to 101 kPa. The results show that both the pressure and fuel mole fraction have a nonlinear correlation with the flash point of the miscible fuel specimens like the correlation provided in this paper. For the partially miscible fuel specimens with a lower density than water, the water content has almost no influence on the flash point. The fire risks of the experimental results were analysed based on the standard GB50160‐2008, which shows that the fire risk becomes higher at low pressures, and there is a critical pressure at the turning point of the change in fire classification. A method to achieve the critical low pressure of different fuels or aqueous solutions from the fire hazard classification is derived in this paper.
