主 题:Liquid CO_(2) Hydrate formation Sequestration Kinetic Water conversion
摘 要:CO_(2)sequestration in marine sediments as solid hydrates is a potential way to capture and store anthropogenic CO_(2).In this study,hydrate formation from liquid CO_(2)in marine sediments was simulated in a glass beads bed,and the factors affecting the kinetics of hydrate formation were *** results indicated that the rapid initial hydrate formation with a high driving force always increases the mass transfer resistance,which slows down hydrate *** final ratio of water conversion is higher under conditions of low temperature and higher pressure.A smaller particle size is conductive to initial CO_(2)hydrate growth,but the water conversion ratio in a bed with larger particles is slightly *** with other factors,the change in water saturation has an obvious effect on the final water *** inhibit the initial hydrate formation during the injection process,in this paper,a kinetic inhibitor is proposed for pre-injection into marine *** work shows that at a low pressure,a lowconcentration inhibitor has an obvious inhibition effect on hydrate ***,at a high pressure,it is necessary to increase the concentration of inhibitor to produce an obvious inhibition effect.
