Molecular simulation on CO2/H2S co-adsorption in organic and inorganic shale nanopores

Silicone oils aided fabrication of paraffin wax coated super-hydrophobic sand: A spectroscopic study

“…Firstly, to find the best adsorption position for paraffin and silicone oil on SiO 2 , GCMC technique was used. The GCMC has been successfully applied in many investigated systems to study the adsorption of several fluids in different solid surfaces, such as gases in organic-inorganic slit pores [ 14 ], hydrogen sulfide and carbon dioxide co-adsorption in organic and inorganic shale nonopores [ 15 ], and methane storage on nano-pores [ 16 ]. The results of GCMC simulations can provide valuable insights into the mechanisms and factors that control adsorption phenomena at the nanoscale level.…”

The effect of H2S content on acid gas migration and storage in shale reservoir by numerical simulation

“…The H 2 S content of acid gas has an influence on the fluid properties (including density, viscosity and solubility) and interactions between acid gas, brine and rock (including wettability and mineralization process). 2,[11][12][13][14][15][16][17] In previous study, the effect of changes in the acid gas density, viscosity, and solubility induced by H 2 S content on the acid gas migration has been analyzed. 9,10,14,18,19 The results indicate that the H 2 S impurity results in a relatively smaller distribution range of the plume spread.…”
