文摘
- •
Amine-based nanofluids were prepared to remove CO2 and H2S from a natural gas stream.
- •
Absorption of H2S was deteriorated by addition of silica nanoparticles to DEA.
- •
Al2O3-DEA nanofluid enhances H2S mass transfer relative to the base fluid.
- •
Effective absorption ratio for CO2 is higher than 1 in all conditions.
- •
Amount of CO2 absorption with SiO2 nanoparticle is more than Al2O3 nanoparticle.
