“…The calculation of the explosion limit of the exhaust gas is based on the Le Chatelier formula, with an upper explosive limit of 14.99% and a lower explosive limit of 4.99%. The critical value of the oxygen content in the exhaust gas calculated via the stoichiometric method is 9.98%.…”

Air injection is a very important technique that is used to enhance the recovery of light oil. To investigate the safety of exhaust gas in an air injection process for light oil reservoirs, static low-temperature oxidation experiments were carried out on oil samples from a block of the Liaohe oilfield in northeast China. The effects of the temperature (80−140 °C) and pressure (10−20 MPa) on the oxygen content of the exhaust gas were studied. It was found that the oxygen consumption rate increases with the temperature. When the temperature rises to 130 °C, the oxygen content in the exhaust gas is much lower than the theoretical calculation of the safe oxygen content, and when the temperature reaches 140 °C, it is nearly exhausted. The effect of the pressure on the oxygen consumption rate is extremely low. Using a component analysis of the crude oil prior to and after the reaction, we observe that aromatic hydrocarbons are barely involved in the reaction at temperatures less than 120 °C. However, when the temperature increases above 130 °C, the aromatic hydrocarbons contribute to the reaction, which results in a large amount of oxygen consumption. Therefore, if the temperature can be controlled within 130−140 °C during the air injection process at the Liaohe oilfield, the oxygen content of the exhaust gas will remain in a safe range.

“…Van den Schoor et al 203 experimentally determined the FIP points of C 2 H 4 −N 2 −air, H 2 −N 2 −air, and C 2 H 4 −H 2 −N 2 −air. The FIP was approximated by the following considerations: (a) the LFL does not change with the addition of N 2 ; (b) at the FIP the equivalence ratio is equal to unity.…”

Flammability limits play an important role in combustion research, industrial applications, and fire safety. This article provides a comprehensive review of recent developments in the fundamental understanding of flammability limits and their experimental determination as well as estimation methods for pure fuels and fuel mixtures. The article begins with a discussion of the importance and challenges of determining flammability limits. It then presents the theoretical, computational, and experimental methods available to understand the mechanism of flammability limits and to quantify them. The experimental setups using cylindrical and spherical vessels to determine the flammability limits are discussed. The effects of buoyancy, thermal radiation, and flame stretch are examined. The relationship between the fundamental flammability limits and the extinction limits of stretched flames via strain and radiation is presented. The effects of initial temperature, pressure, mixtures of different fuels, and diluents are examined, and available estimation methods are presented. Finally, the flammability limits of renewable and alternative fuels are addressed and strategies for estimating the flammability limits of these fuels are presented.
