In this study, the explosion parameters of stoichiometric methane-air diluted with nitrogen (N 2 )/carbon dioxide (CO 2 ) blends, that is, maximum explosion pressure (P max ), laminar burning velocity (S L ), and activation temperature (T a ), were investigated in a closed cylinder vessel. The concentrations of the dilution blends were 10% and 20%. The explosion pressure history was recorded by a pressure transducer. The results indicated that the dilution effect of CO 2 is more sensitive than that of N 2 . For a given dilution concentration, both the maximum explosion pressure and the laminar burning velocity decrease with the increase of CO 2 . In addition, the activation temperature is higher for increased CO 2 blends, demonstrating again that the diluent influence of CO 2 is more prominent.

“…In fact, not all of the flammable gases in the vessel have reacted. (2) The quenching effect and the heat loss to the walls in a small explosion vessel during the flame propagation are also important factors to be considered. , In particular, the heat loss to the unit surface increases linearly with the increase of the initial pressure . As also indicated in the results of Tang et al, the flame front instability and turbulence tend to exist under high pressure.…”

Flammability and Explosion Characteristics of Methane in Oxygen-Reduced Air and Its Application in Air Injection IOR Process

Air injection into oil reservoirs has been widely applied in oilfields for improved oil recovery, while the safety of the process is of great concern due to the explosion of the mixtures of natural gas (mainly methane) and injected air at high pressure and high temperature. Oxygen-reduced air flooding (ORAF) has been proposed to eliminate the explosion risks. The combustion and flammability characteristics of methane–air mixtures at elevated pressure and temperature are also important for natural gas engines and air compressors. In this study, an experimental setup was used to measure the flammability limits and explosion energy of methane in oxygen-reduced air (ORA) at pressures up to 15 MPa and 373 K and compared with methane–air mixtures. The experimental results show that the flammability limits of methane in ORA can be significantly reduced or narrowed, which can reduce explosion risks. At high pressures, the low flammability limit of methane in ORA is reduced, and its upper flammability limit is increased, which follows a similar pattern with methane–air mixtures. The explosion energy of methane in ORA can be also greatly reduced due to the lack of oxygen. Finally, the explosion risks in applying the ORAF technique for improved oil recovery have been analyzed.
