“…Because the absorbent of the absorption system is a binary mixture and the nanofluid is considered as a single phase fluid by the definition, the absorption medium with nanoparticles is named as binary nanofluid [8]. Kim et al [8][9][10] and Ma et al [11] found that the binary nanofluids have remarkable enhancement for ammonia bubble absorption rate by experiments. However, few theoretical and analytical investigations about bubble absorption in binary nanofluids are developed at present.…”

An absorber is a major component in the absorption refrigeration systems, and its performance remarkably affects the overall system performance. A mathematical model for ammonia absorption from a bubble expanding at a submerged nozzle into a binary nanofluid was developed to analyze the effects of binary nanofluid on ammonia absorption in the forming process of a bubble. The combined effects of nanoparticles on heat transfer, mass transfer, and bubble size all were considered in the model. The concentration of nanoparticles, the radius of the nozzle, and the flow rate of ammonia vapor were considered as the key parameters. The numerical results showed that the enhancement of binary nanofluid for bubble absorption has the analogous tendency with the mass transfer enhancement of binary nanofluid. The diameter of the nozzle and the flow rate of ammonia vapor hardly affect the enhancement of the binary nanofluid for the absorption of bubble growing stage. The current investigation can result in a better understanding of the absorption process occurring in thermally driven absorption refrigeration systems.

Nanoparticles suspended in solutions are considered to have the potential to enhance gas‐liquid mass transfer and have been studied for gas separation. In order to reveal the mechanisms of kinetics enhancement, the diffusion and reaction process should be carefully examined. In this paper, CO2 absorption kinetics of amine‐based solutions with additive of SiO2 and Al2O3 nanoparticles were investigated by wetted‐wall column experiments. Measurements at different conditions, including solid loading, pressure, and solvent flow rate, show a significant enhancement on CO2 absorption kinetics. The experiment and model analysis indicate that the micro convective motion induced by particle Brownian movement plays a primary role in mass transfer enhancement. Three solutions, MEA, MDEA, and PZ which have different kinetics were selected to study the impact of nanoparticles on absorption kinetics of solutions with different reaction rate. It is interesting to find that the increased ratio of absorption kinetics by nanoparticle follows the same order with increased solvent reaction rate with CO2, which is PZ > MEA > MDEA. The wetted‐wall kinetic model indicates that a diffusion controlled kinetics for PZ solution could result in much more significant kinetic enhancement with additives of nanoparticles. By operation conditions optimization, the liquid side mass transfer rate of MEA solution can be increased over 15%.© 2015 Society of Chemical Industry and John Wiley & Sons, Ltd

Examining fluid behavior in the presence of nanoparticles is essential to understand the displacement mechanism when a nanoparticle is used as novel enhanced oil recovery (EOR) method. Recent investigations showed that nanoparticles have great potential for EOR in the lab-scale. Since its displacement mechanism is not yet clearly understood, studies about fluid-fluid and fluid-rock interactions will be essential as a way to unlock how its mechanism.Saline water is studied in the presence of hydrophilic silica nanoparticles at different conditions such as temperature, concentration, various salt ions and nanoparticle size and initial rock wettability. The fluid properties measurement involves density, viscosity, pH and surface conductivity. Crude oil from a field in the North Sea is employed to measure interfacial tension between oil-phase and aqueous phase (saline water and nanofluids) at different temperatures. Contact angle is also measured among quartz rock as solid phase and those fluid phases at different initial rock wettability.These compatibility tests is useful to have better understanding about displacement mechanism and boundary of using nanoparticles as EOR method (Nano EOR) before applying in the field-scale. The processes and observations are outlined and also further detailed in the paper as a part to unlock nanoparticles flooding as a future promising EOR method.
