  • Study on the decomposition conditions of gas hydrate in

    The decomposition pressures of methane hydrate in 20–40 and 80–100 mesh are in the same range as for the 60–80 mesh quartz sand The first measured decomposition pressures for methane hydrate in 20–40, 60–80, and 80–100 mesh quartz sand were 382 MPa, 377 MPa, and 378 MPa, respectively This implies that there was only a small difference in hydrate dissociation pressure when the sand …
