چکیده    How co2 and h2s are removed from a natural gas stream, through a nanofluid containing nanoporous graphene in diehanolamine (dea) is revealed. the appropriate values are chosen for the nanosheet dosage and the liquid and gas flow rates to be applied in the absorption experiments. these experiments are run in a laboratory scale wetted wall column. the nanosheet concentration is within 0.005 to 0.5 wt % range. the surfactants and ultrasonic treatment is administered to prepare stable nano-fluids. it is found that applying nanoporous graphene in dea has a significant affect on co2 and h2s absorption in comparison with dea. the absolute zeta potential values of nanofluids are greater than +35 mv. the effect of different parameters including nanosheet, co2 and h2s concentrations, in the feed gas stream (two different samples) on simultaneous absorption of h2s and co2 from co2-h2s-ch4 gas mixture is studied. by processing sample #1, abstract i.e, an improvement in co2 absorption to 39% and h2s absorption up to 9% is observed at 0.1 wt% of nanoporous graphene/dea nanofluids.
