Carbon dioxide (CO2) phase transition fracturing is widely regarded as a promising coal seam mining technology because it can effectively enhance the permeability of coal pore structure and prevent gas outbursts. A CO2 phase transition impact pressure test system was designed and developed, and the effects of different factors on phase transition impact pressure were investigated by combining CO2 release experiments and smoothed particle hydrodynamics (SPH) numerical simulation. In addition, based on the Peng-Robinson (P-R) equation and the pipeline pressure drop formula, new mathematical models of the pressure in the buffer tank and the velocity of gaseous CO2 at the nozzle were obtained. The results show that the CO2 phase transition impact pressure can divided into rapid boost, fluctuation, and attenuation stages. The impact distance and impact angle have the most significant effects on pressure. The model of the pressure in the buffer tank and the velocity of gaseous CO2 at the nozzle well-simulated the experimentally obtained impact pressure curves of CO2. The impact results can be applied to reference for the application of CO2 phase transition fracturing technology.

“…In another approach, van den Berg published new scaled overpressure curves (van den Berg, 2008) from a modeling of expansion controlled shock production, based on the assumption that the explosive evaporation of the liquid is as fast as the inertia of the expanding mixture (van den Berg et al, 2004(van den Berg et al, , 2006. In parallel to the modeling research, BLEVE experiments have been conducted over the years, and included a variety of fluids, vessel shape and scale, heating system, and intrumentation (Birk et al, 2006a,b;Birk and Vandersteen, 2006;Balke et al, 1999;Davison and Edwards, 2008;Giesbrecht et al, 1981;McDevitt et al, 1988McDevitt et al, , 1990Johnson et al, 1991;Stawczyk, 2003;Rirksomboon, 1997;van der Voort et al, 2012van der Voort et al, , 2013.

Several methodologies, based on different thermodynamic assumptions and requiring substance properties and thermodynamic data, have been proposed in the literature for the prediction of the mechanical energy released by a Boiling Liquid Expanding Vapour Explosion (BLEVE) and the associated overpressure. A new method, simple and easy to use, is presented which only requires the vessel filling degree and the temperature at failure as input variables to estimate this energy. The polynomial approach has been used to obtain the equation corresponding to the diverse substances most commonly involved in these explosions. The comparison of the predicted values with experimental data shows a good agreement.

“…Twelve groups of experiments in the 40L CO 2 cylinders at various temperatures have been conducted to investigate the temperature dependence of explosive evaporation. The results show that below the homogeneous nucleation temperature, CO2 BLEVE blast does not disappear abruptly, but instead follows a gradual decay [11].…”

SUMMERY&CONCLUSIONSIn this work, a small-scale experiment of solid CO 2 Boiling Liquid Expanding Vapor Explosion (BLEVE) has been conducted and comparisons between experimental results and theoretical results have been performed. The process of solid CO 2 BELVE which can be divided into several phases has been observed clearly. It is verified that SLT can't be the absolute criterion of CO 2 BLEVE, but it is still an important parameter for BLEVE. The possible relationship between the relative pressure rise and the relative pressure drop were found, but it needs more experiments to be verified.Conclusions: The process of CO 2 explosion can be divided into pressure sudden dropping, superheated liquid boiling and extending, pressure recovering unstably then decreasing to ambient pressure.The comparison results of theoretical calculation with experimental data show that solid CO 2 BLEVE may occur below the SLT and may not occur beyond the SLT, so, whether the initial temperature of the liquid reached the limit temperature of the liquid can't be a necessary condition to determine whether the BLEVE will occur. But it is confirmed that the blast effect may be much higher with a higher superheat degree and it is no doubt that SLT is still an important parameter for CO2 BLEVE. So in the CO2 injection process and for the large volumes of high pressure CO2 it is better to decrease the superheat degree under the SLT to avoid CO2 BLEVE accident. This can be an effective method for BLEVE risk management.It is also found that thermal stratification appears in the liquid zone, and from top to bottom are the gas phase, gasliquid phase and liquid phase, respectively. This may be the reason why BLEVE may happen both below and beyond the SLT. Meanwhile, both the amount of depressurizations and the rate of depressurizations are found to be positively correlation with the amount of depressurization and the rate of depressurization. And there is a certain kind of fixed proportional relationship between relative pressure rise and relative pressure drop and further studies are still needed.
