“…The effect of temperature on surfactant solution/paraffinic oil IFT was controversial compared to that of the aromatic oil. Hence, the minima in IFT with temperature can be explained by the synergetic effect of different oils (Mosayebi et al, 2016). In the present work, n-decane was used as a model oil; thus, we suggest another explanation of the observed phenomenon.…”

Surfactant flooding has widely been used as one of the chemically enhanced oil recovery (EOR) techniques. Surfactants majorly influence the interfacial tension, γ, between oil and brine phase and control capillary number and relative permeability behavior and, thus, influence ultimate recovery. Additives, such as nanoparticles, are known to affect surfactant properties and are regarded as promising EOR agents. However, their detailed interactions with surfactants are not well understood. Thus, in this work, we examined the influence of silica nanoparticles on the ability of surfactants to lower γ and to increase viscosity at various temperatures and salinities. Results show that the presence of nanoparticles decreased γ between n‐decane and various surfactant formulations by up to 20%. It was found that γ of nanoparticles–surfactant solutions passed through a minimum at 35 °C when salt was added. Furthermore, the viscosity of cationic surfactant solutions increased at specific salt (1.5 wt.%) and nanoparticle (0.05 wt.%) concentrations. Results illustrate that selected nanoparticles–surfactant formulations appear very promising for EOR as they can lower brine/n‐decane interfacial tension and act as viscosity modifiers of the injected fluids.

“…Chemical flooding was found to be among the most efficient Enhanced Oil Recovery (EOR) methods [6,7]. Surfactants are special classes of molecules which have a hydrophobic tail and hydrophilic head group, and the most stable condition for these molecules is at the oil-water interface [8][9][10]. Surfactants have a great potential in EOR applications and are used to enhance the recovery process efficiently by increasing the quantity of the residual oil extracted after the secondary recovery process, which can account for approximately 60% of the original oil in place [11][12][13].…”

Experimental Investigation of Surfactant Partitioning in Pre-CMC and Post-CMC Regimes for Enhanced Oil Recovery Application

et al. 2019

The applications of surfactants in Enhanced Oil Recovery (EOR) have received more attention in the past decade due to their ability to enhance microscopic sweep efficiency by reducing oil-water interfacial tension in order to mobilize trapped oil. Surfactants can partition in both water and oil systems depending on their solubility in both phases. The partitioning coefficient (Kp) is a key parameter when it comes to describing the ratio between the concentration of the surfactant in the oil phase and the water phase at equilibrium. In this paper, surfactant partitioning of the nonionic surfactant Alkylpolyglucoside (APG) was investigated in pre-critical micelle concentration (CMC) and post-cmc regimes at 80 °C to 106 °C. The Kp was then obtained by measuring the surfactant concentration after equilibration with oil in pre-cmc and post-cmc regimes, which was done using surface tension measurements and high-performance liquid chromatography (HPLC), respectively. Surface tension (ST) and interfacial tension (IFT) behaviors were investigated by performing pendant and spinning drop tests, respectively—both tests were conducted at high temperatures. From this study, it was found that APG was able to lower IFT as well as ST between water/oil and air/oil, and its effect was found to be more profound at high temperature. The partitioning test results for APG in pre-cmc and post-cmc regimes were found to be dependent on the surfactant concentration and temperature. The partitioning coefficient is directly proportional to IFT, where at high partitioning intensity, IFT was found to be very low and vice versa at low partitioning intensity. The effect of temperature on the partitioning in pre-cmc and post-cmc regimes had the same impact, where at a high temperature, additional partitioned surfactant molecules arise at the water-oil interface as the association of molecules becomes easier.

Summary To develop kinetic model for methanol steam reforming, the experiment tests at various operating conditions (ie, temperature: 180°C‐500°C, pressure: 1‐11 bar and H2O/CH3OH ratio [S/M] of 0.75‐3.75) on Co‐Cu‐Zn/γ‐Avnl2O3 catalyst. The kinetic model development relied on Langmuir‐Freundlich (LF) method. Also, three second‐order model applied by using response surface methodology‐box behnken design (RSM‐BBD) approach to predict the various responses including methanol conversion, H2 and CO yield. The deviation of kinetic model in predicting responses was 10.86% and showed good forecasting H2 yield compared to other responses. However, RSM‐BBD approach had a better ability in predicting the methanol conversion with error of 5.21% than products selectivity. The methanol conversion and CO yield were almost constant (equal zero) up to 260°C. The methanol conversion of 100% reached close to 500°C at pressures of 1 and 6 bar. An augmentation in S/M led to enhance in methanol conversion and H2 yield, while this trend for CO yield was reverse.
