Mathematical Model of the Effect of Self-Preservation of Gas Hydrates
- 13 Downloads
A diffusion model of dissociation of a plane layer of gas hydrate into ice and gas has been presented, which permits modeling the effect of self-preservation of gas hydrates. In this model, the gas-hydrate dissociation into ice and gas is described with account taken of the internal kinetics of the process and of the pore structure of the formed ice layer. Calculated data obtained within the framework of a quasi-stationary approximation for the cases of dissociation of plane layers of methane hydrate and carbon-dioxide hydrate into ice and gas have been given as an example.
