We study the effects of pressure on crude-oil oxidation kinetics using ramped temperature oxidation for a large range of pressures and heating rates (1.5, 2.0, 5.0, 7.5, 8.0, 10.0, 15.0, 20.0, and 30.0 °C/min). Results are relevant to the combustion of crude oil within reservoirs to produce heat and pressure that enhance oil recovery. Our study results suggest that the activation energy of global reactions is sensibly independent of changes in both partial pressure and total pressure (100−2000 psig) with values ranging between 50 and 60 kJ/mol for the low-temperature oxidation regime (roughly 250 °C) and 90−100 kJ/mol for the hightemperature oxidation regime (roughly 350−450 °C). Three different crude oils were tested. For one of the crude oils, we observe an increasing trend in oxygen consumption as the total pressure is increased up to a particular pressure (∼500 psig), after which it remains constant. This trend is, apparently, associated with the evaporation of relatively lighter components at low pressures, decreasing the amount of oil available for fuel generation. Total oxygen consumption starts to decrease again at very large pressures (>1500 psig), and we associate this trend with water phase behavior at these conditions.

“…Different from the experimental test [37], case study [28], and simulation design approach are always used [38][39][40], we try to simulate the boarding process with different boarding strategies on a specific aircraft to find out which strategy works the best. e computer simulation program used for this paper is based upon the Airbus A320, which has three rows with four first-class seats and 23 rows with six coach class seats.…”

The boarding efficiency is essential for all airlines due to potential competitive financial pressure. Therefore, the turnaround time needs to be cut down for a shorter boarding time. The paper devised a feasible boarding strategy which combines the management mode decision of passenger boarding with the intelligent deployment of the operation process and will be likely to improve the efficiency of the passenger travel chain. Among which, to decrease the boarding time is an effective method. Firstly, we proposed an improved outside-in strategy, which costs shorter boarding time based on the existing outside-in strategy. However, this method requires passengers to stand in queue in advance. Secondly, we put forward a deterministic queue-ordered boarding method to improve it. Finally, we simulated and applied the strategy to a narrow-body aircraft A320 and a wide-body A380, both representative for their type of airplanes. It turns out that this strategy performs better than the current widely used method and will be able to increase boarding efficiency and thus maximize the profits of airlines.

“…Furthermore, although combustion tube experiments 7 and separate measurements of oxidation kinetics in a plug-flow reactor 8 represent integral tools for characterizing ISC processes, accurate numerical predictions require consistent and reliable experimental data that must be analyzed carefully to obtain representative parameters that allow for the modeling of the process at larger scales. 9 Because flow and reaction kinetics during ISC are strongly coupled, each topic is typically studied separately using experiments and then related through numerical modeling.…”

We developed a novel technique based upon time-lapse infrared (IR) images to relate the effects of crude-oil oxidation kinetics on flow during one-dimensional homogeneous and heterogeneous laboratory-scale combustion tube experiments. We performed combustion tube experiments under variable conditions including different sands (i.e., grain-size distribution), air injection rate history (constant versus variable), degree of packing heterogeneity, and reaction heterogeneity. The latter is achieved by using reaction enhancing nanoparticles in controlled packing configurations. During every experiment, we obtain high-resolution IR images of the outer wall of the combustion tube that we calibrate using point-wise temperature measurements from a thermocouple. Here, a new experimental workflow that uses these images and combines knowledge obtained from kinetic cell experiments is used to isolate the spatial zones within the tube where so-called low-temperature and high-temperature oxidation (pseudoreaction regimes) occurs during combustion tube experiments for the first time. Additionally, the IR imaging technique is shown to provide new insight into the propagation of the combustion front in homogeneous and heterogeneous systems and, importantly, visualizes gravity drainage of hot oil.
