decomposition of methane hydrates in sand

Decomposition of methane hydrates in sand, sandstone

[1] Decomposition conditions of methane hydrates in sediments were measured during formation‐decomposition cycles. As test sediments, we used silica sand, sandstone, and clays (kaoline and bentonite), which are typical natural materials known as hydrate bearing sediments, and the range of samples cover a range of water saturating abilities.

Microscopic measurements on the decomposition

In this work, the decomposition behaviour of methane hydrate in porous media was investigated microscopically using powder X-ray diffraction, cryogenic scanning electron microscopy and in situ Raman spectroscopy. The effect of grain sizes on the decomposition of methane hydrate was measured. The results showed that

KINETICS OF HYDRATE FORMATION AND

The decomposition of methane hydrate crystals formed in sediment at 1.0, 4.0, and 7.0 °C was studied in a new apparatus designed to accommodate three different size volume beds of silica sand

Microscopic measurements on the decomposition behaviour of

decomposition time for hydrate formed in sands did not decrease with the decrease in particle size. The shortest decomposition time was observed for the sands with the particle size range of 38–55 mm, which was less than 30 minutes. Moreover methane hydrate was found to decompose faster in the porous medium containing 3.5 wt% NaCl, which

[1907.03052v1] Study of methane hydrate formation and

06-07-2019· This paper reports results of the synchrotron-based tomography experiments for studying the methane-hydrate formation/decomposition in sand samples. Fast scanning times (70 secs) provided successive images (every 2-15 min) for a detailed study of these processes. During the methane gas-hydrate formation we observed water flows that we connect to the effect of cryogenic

KINETICS OF HYDRATE FORMATION AND

Kinetics of hydrate formation and decomposition of methane hydrate formed in silica sand particles were studied in detail at three temperatures of 7.0, 4.0 and 1.0°C, respectively. A new apparatus was setup to study the decomposition behavior of the methane hydrate formed in the bed of silica sand particles. Six thermocouples are placed in different locations to study the temperature profiles
