Straightforward dimensionless experimental formulae for flash point of binary mixtures of two flammable components

Abstract

Dimensionless experimental formulae based on a rational reciprocal function for correlation of flashpoint data of binary mixtures of two flammable components have been developed. The formulae are based on data obtained from flash-point experiments. The proposed approach requires only two coefficients, molar fraction of components and flashpoint temperatures of the pure flammable components to be known in advance. Literature data were used for formulae verification and validation obtained results indicate that accuracy is comparable and to some extent better than that of conventional flash point prediction models. Dimensional analysis and scaling of data have been performed in order to define the correct construction of the equation fitting flash-point data in dimensionless form using the independent variables suggested by Catoire. Stefan number relevant flash-point of a single compound or a blend has been defined

Evaluation of safety parameters of light alkenes by means of detailed kinetic models

“…Hertzberg (1982) reported that the flammability limits are correlated to a limiting laminar burning velocity (S u,lim ) that depends on the gaseous properties. More recently, Hristova et al (2012) correlated the flammability limits to the molar weight, as well as the boiling point, of the analysed substance. Finally, semi-empirical methodologies based on a thermal equilibrium theory, such as the adiabatic flame temperature method (Di Benedetto, 2013), based on the assumption of a constant value for the adiabatic flame temperature at flammability limits composition, have been proposed.…”
