Molecular Insights into the Inhibition Mechanisms of Modified PVCap Kinetic Inhibitors in Hydrogen Sulfide-Containing Gas Hydrate Systems

Abstract Gas hydrate blockage threatens pipeline safety in sour gas reservoirs, where hydrogen sulfide (H2S) accelerates hydrate formation and the conventional kinetic inhibitor poly N-vinylcaprolactam (PVCap) severely degrades. Microsecond-level molecular dynamics (MD) simulatio...

Synergistic Reaction Pathway Regulation and Process Simulation of Piperazine-Promoted AMP-EG Water-Reduced Absorbents for Low-Energy CO2 Capture

Abstract An AMP-PZ-EG-H2O water-reduced absorbent was developed for CO2/CH4 separation in natural gas decarbonization. Promoter screening and composition optimization identified PZ as the preferred promoter and an AMP/PZ mass ratio of 2:1 with a total AMP-PZ-EG mass fraction of 5...
