High temperature nanofluids based on therminol 66 for improving the heat exchangers power in gas refineries

Ionanofluids: A review on its properties and thermal applications

“…He proposes a different theory instead, one that depends on longer-range interactions between the nanoparticles in the surrounding liquid. Adding 0.1 weight percent of SiO 2 and AI 2 O 3 nanoparticles to Therminol 66 at temperatures between 280 and 320 °C did not appreciably change the fluid's density or viscosity compared to the base substance, according to a recent study by Safaei et al [101]. There is currently no comprehensive literature on the density and high temperature heat capacity of nanofluids.…”

Electrification of Industrial Processes as an Alternative to Replace Conventional Thermal Power Sources

“…The predominant methods to improve heat transfer in this equipment include increasing the transfer surface area, vibrating the surfaces or transfer fluids, improving the physical properties of certain types of coolant, and finally, adding solid nanoparticles such as carbon-acetone in the presence of magnetic fields [26]. Research in the field of nanotechnology is also contributing to the development of applications in the field of heat transfer for industrial equipment, as well as some proposed nanoparticles such as metal oxides SiO2 and Al2O3 [27] confer to the Similar pilot-scale applications for processes with the use of methane and CO 2 as carbon capture and hydrogen generation alternatives have to do with implementing thermal reactors using plasma generated with high-frequency electricity [21]. Plasma is generated by passing an electric current through a gas.…”

In other tests, the hydrothermal characteristics of some so-called ferrofluids (water with 4 vol%) have been evaluated in heat exchangers of different types.…”
