Experimental study and analysis of CO and SO absorption in various water-based nanofluids by response surface methodology.

The absorption of acidic gases in the oil and gas industries is important due to their toxicity and corrosive effects. Recently, the application of nanofluids based on aqueous or organic solvents as absorbents has been examined by a variety of researchers. In this study, a single bubble column was exploited to study the effect of water-based nanofluids on the absorption processes of SO and CO using response surface methodology (RSM) based on Box-Behnken three-level experiment design.
