“…It should be noted that the results at 200 K for the mixture containing propane were not reported, since it was liquid at that temperature and the corresponding equilibrium composition in the vapour mixture is negligible. The numerical results were compared with the experimental data (Table 2) reported by Cui et al (2016) and Li et al (2011) for low temperature methane, by Liao et al (2005) for natural gas at room temperature, by Shen et al (2017) for methane/ethane mixtures and by Woodward and Pitblado (2010) for mixtures containing propane and ethane.…”

“…In this study, an extended database obtained by gathering additional data from the literature to enlarge the data set employed by Wang et al [ 24 ] was used in order to extend the diversity of the chemicals involved in the mixtures. The new dataset consisting of 181 binary hydrocarbon gases which was taken from the literature [ 6 , 25 , 26 , 27 , 28 ]. A complete list of the detailed compositions of mixtures as well as the LFL values was presented in Table S1 in the Supporting Information .…”

The lower flammability limit (LFL) is one of the most important parameters for evaluating the fire and explosion hazards of flammable gases or vapors. This study proposed quantitative structure−property relationship (QSPR) models to predict the LFL of binary hydrocarbon gases from their molecular structures. Twelve different mixing rules were employed to derive mixture descriptors for describing the structures characteristics of a series of 181 binary hydrocarbon mixtures. Genetic algorithm (GA)-based multiple linear regression (MLR) was used to select the most statistically effective mixture descriptors on the LFL of binary hydrocarbon gases. A total of 12 multilinear models were obtained based on the different mathematical formulas. The best model, issued from the norm of the molar contribution formula, was achieved as a six-parameter model. The best model was then rigorously validated using multiple strategies and further extensively compared to the previously published model. The results demonstrated the robustness, validity, and satisfactory predictivity of the proposed model. The applicability domain (AD) of the model was defined as well. The proposed best model would be expected to present an alternative to predict the LFL values of existing or new binary hydrocarbon gases, and provide some guidance for prioritizing the design of safer blended gases with desired properties.

“…Studies on explosion propagation parameters in enclosures (maximum explosion pressures, maximum explosion times, maximum rates of pressure increase, and deflagration indices) of ethane-air mixtures were reported by some researchers in various initial conditions (pressure, temperature, and equivalence ratio) using measurements in cylindrical [2][3][4] or spherical [5][6][7][8][9][10] vessels. In addition to the experimental measurements, numerical simulations of the explosion process have been used in the study of the explosion parameters of ethane-air mixtures [8][9][10][11].…”

Dynamics of Pressure Evolution during Gaseous Ethane–Air Mixture Explosions in Enclosures: A Review

The study here presents data from the literature regarding the characteristic parameters of explosion propagation in gaseous ethane–air mixtures. The maximum explosion pressures, maximum explosion times, maximum rates of pressure increase, and deflagration indices from experimental measurements are discussed and analyzed against the initial pressure, initial temperature, and equivalence ratio, as well as the explosion vessel characteristics. Ethane is used for ethylene production, as a refrigerant in cryogenic systems, as an alternative clean fuel in the power generation industry and automotive propulsion, and for many other applications. Therefore, the explosion characteristics of its mixtures with air are of great interest for explosions occurring after accidentally forming flammable mixtures, as well as for the prediction of combustors’ performances and/or engines that work in different conditions.
