To determine the suitable operating conditions for hydrate-based CO2 separation process from a fuel gas mixture, hydrate nucleation and growth kinetics of simulated (39.2 mol % CO2/H2 mixture) in presence tetra-n-butyl ammonium bromide (TBAB) are investigated. The experiments were conducted at TBAB concentration range 0.14−1.00 %, temperature 275.15−282.45 K, driving force 1.00−4.50 MPa, gas/liquid phase ratio 0.86−6.47, time 15−120 min. It is found that addition not only shortens induction...
The equilibrium hydrate formation conditions for the gas mixture of CO2 and H2 with tetrabutyl ammonium bromide (TBAB) are measured. data show that TBAB can reduce pressure as an additive mole fraction (0.14, 0.21, 0.29, 0.50, 1.00, 2.67) %. experiments were carried out in temperature range (274.05 to 288.55) K (0.25 7.26) MPa. + is remarkably lower than at same decreases increase concentration TBAB. In addition, avoid pure hydrate, which there no or H2, above mixture, from (0.14 % also
Trapping CO2 in hydrates is a promising approach to reduce the greenhouse gas emissions. This work presents efficient separation process of from simulated fuel (39.2 mol % CO2/H2 binary mixture) based on hydrate crystallization presence tetra-n-butylammonium bromide (TBAB). The experiments were carried out TBAB concentration range 0.14−1.00 %, temperature 275.15−285.15 K, driving force 1.00−4.50 MPa, gas/liquid phase ratio 0.86−6.47, and growth time 15 120 min. results indicate that increase...
The behavior of hydrate formation in porous sediment has been widely studied because its importance the investigation reservoirs and drilling natural gas hydrate. However, it is difficult to understand nucleation growth mechanism on surface nanopores media by experimental numerical simulation methods. In this work, molecular dynamics simulations CH4 presence clay are carried out. configurations microstructure properties analyzed for systems containing one H2O layer (System A), three layers...
Vegetation is a fundamental component of terrestrial ecosystems, and accurately assessing the effects seasonal climate variations, extreme weather events, land use changes on vegetation dynamics crucial. The Ganjiang River Basin (GRB), key region for water conservation recharge in southeastern China, has experienced significant variable past. However, comprehensive evaluations how these have impacted remain limited. To address this gap, we used machine learning models (random forest XGBoost)...
This work presents the thermodynamic study of separating CH4 and CO2 from simulated landfill gas (LFG) [CO2 (0.45) + (0.55)] based on hydrate crystallization in presence tetra-n-butyl ammonium bromide (TBAB), tetrahydrofuran (THF), dimethyl sulfoxide (DMSO), their mixtures. The mole fractions TBAB, THF, DMSO aqueous solutions were fixed at 0.0234, 0.0556, 0.0165, respectively. equilibrium formation conditions measured by T-cycle method temperature range (274.15 to 294.95) K pressure ranges...
Natural gas hydrate (NGH) formation behavior in porous sediment influences the investigation of reservoirs and exploitation NGH. However, its molecular mechanisms NGH remain unclear. In this work, we present CH4 smectite system through dynamics simulation. The microstructure configurations properties are analyzed. results find pure H2O solution CH4-H2O homogeneous initial configuration layer reveal different influence on formation. gas–water ratio (ri) affects diffusion layer, two types...
