Application of Nanofluids in CO2 Absorption: A Review
نویسندگان
چکیده
The continuous release of CO2 into the atmosphere as a major cause increasing global warming has become growing concern for environment. Accordingly, absorption through an approach with maximum efficiency and minimum energy consumption is paramount importance. Thanks to emergence nanotechnology its unique advantages in various fields, new was introduced using suspended particles base liquid (suspension) increase absorption. This review article addresses performance nanofluids, preparation methods, their stability, which one essential factors preventing sedimentation nanofluids. aims comprehensibly study contributing mainly role liquids reason behind selection.

Stability and Thermal Conductivity Characteristics of Nanofluids (H2O/CH3OH + NaCl + Al2O3 Nanoparticles) for CO2 Absorption Application
In this study, the nanofluids are produced by dispersing Al2O3 nanoparticles in the H2O/CH3OH binary mixtures using an ultrasonic equipment. Solid Sodium Chlorides (NaCl) with a fixed mass fraction are dissolved in the binary mixture for CO2 absorption. The main objective of this paper is to measure the thermal conductivity of the Al2O3 nanofluids using the transient hot-wire method. The experi...
متن کاملModeling and Simulation of CO2 Absorption Enhancement in Hollow-Fiber Membrane Contactors using CNT–Water-Based Nanofluids
Absorption of CO2 from a gas mixture containing CO2 and nitrogen by water-based CNT nanofluids in gas–liquid hollow fiber membrane contactor was modeled and solved using COMSOL Multiphysics 5.4. The model assumed partial wetting of the membrane, along with diffusion in the axial and radial directions. In addition, Brownian motion and grazing effects were both considered in the model. The main c...
متن کاملNanofluids for Heat Transfer Enhancement – A Review
A nanofluid is a dilute liquid suspension of particles with at least one critical dimension smaller than ~100 nm. Research works so far suggest that nanofluids offer excellent heat transfer enhancement over conventional base fluids. The enhancement depends on several factors such as particle shape, particle size distribution, volume fraction of nanoparticles, temperature, pH, and thermal conduc...
متن کاملAl2O3-based nanofluids: a review
Ultrahigh performance cooling is one of the important needs of many industries. However, low thermal conductivity is a primary limitation in developing energy-efficient heat transfer fluids that are required for cooling purposes. Nanofluids are engineered by suspending nanoparticles with average sizes below 100 nm in heat transfer fluids such as water, oil, diesel, ethylene glycol, etc. Innovat...
