Controlling effect of CO2 hydrate membrane on CO2 dissolution into water from the surface of liquid CO2

Abstract Kinetic study on the dissolution of CO 2 from the surface of a liquid CO 2 droplet in water was conducted. It was proved that the dissolution rate of CO 2 into water is dominated by the decay of CO 2 hydrate on the surface of the droplet. Kinetic studies on the dissolution of CO 2 from the liquid CO 2 pool, the diffusion in the ocean and advection of CO 2 by the bottom ocean current were also carried out. Thin membrane of CO 2 hydrate on the liquid CO 2 pool controls the CO 2 dissolution into seawater, the depth of static layer between the surface of liquid CO 2 and the upper bottom ocean current reduces the CO 2 diffusion, and the bottom ocean current dilutes the CO 2 concentration.
