Summary: | National audience In recent decades, scientists have made an amazing discovery: methane hydrates in the ocean floor. These solid compounds could represent an energy reserve. Today it is estimated that they contain equivalent carbon under the form of methane in a huge quantity, twice as much as all deposits of natural gas, oil and coal. In the near future, we need evaluating the possibility to produce this new source of energy, particularly in replacement of oil and coal. The main question concerns the technology to be used because the methane hydrates are distributed in sediment, and they participate to their consolidation. In this paper we present a method to study the thermodynamic of CO 2 -CH 4 clathrate hydrates, which is the prior step before testing and modeling the replacement of methane hydrate by CO 2 hydrate after injection of CO 2 gas. |
