Effects of graphene oxide (GO) nanoparticle and SDS on storage capacity of CO2 in hydrate

In this study, the effect of nanoparticle of graphene oxide and surfactant sodium dodecyl sulfate (sds) 400 ppm on the storage capacity of CO2 in hydrate was investigated. A laboratory system was developed for hydrate formation experiments. The experiments were carried out in the range of pressure 36-40 bar, temperature range from 273.35 k to 278.65 k, in the presence of graphene oxide and sodium dodecyl sulfate. Experimental results showed that by increasing the pressure at constant temperature for net water, storage capacity increased by 11%, and the storage capacity increased by 14% by decreasing the temperature at the constant pressure (36 bar). Adding sds increased storage capacity by 26%, while adding graphene oxide increased 4.2% of storage capacity. For this purpose, design expert software and response surface test method and historical method were used. Also, a mathematical equation was proposed to estimate the cot storage capacity in hydrate.
