Permeability experiments on the methane hydrate in quartz sands and its model verification
The permeability of porous media is an important physical parameter that affects the exploitation of natural gas hydrate. At present, however, the measurement methods and porous media used for investigating the permeability are so different that neither ...

Assessment of Hydrate Prediction Software for MEG–Water–NaCl Systems
ABSTRACT This study evaluates the performance of three industry‐standard simulation tools—Aspen HYSYS (V14), Multiflash (V7.5), and OLGA (V2024.1)—by comparing predicted hydrate dissociation temperatures with experimental data obtained from a PVT sapphire cell.

ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

Joint seismic/electrical effective medium modelling of hydrate-bearing marine sediments and an application to the Vancouver Island margin [PDF]
Remote determination of the hydrate content of marine sediments remains a challenging problem.In the absence of boreholes, the most commonly used approach involves the measurement of Pwavevelocities from seismic experiments.

Could changing ocean circulation have destabilized methane hydrate at the Paleocene/Eocene boundary? [PDF]
During the Paleocene-Eocene Thermal Maximum (PETM, ~55 Ma), marine and terrestrial carbon isotope values exhibit a negative shift of at least 2.5‰, indicative of massive destabilization of marine methane hydrates, releasing ~1100 gigatonnes of methane ...

Estimation and measurement of permeability inside methane hydrate mimicking porous media
The objective of this study is to mimic methane hydrate cores at atmospheric pressure conditions with the same permeability as oceanic methane hydrate cores. This became possible by freezing a solution of water, ethanol, and sodium bicarbonate in Toyoura

Hydrogen Permeability of Tubular Polymer Membranes for Biological Methanation Membrane Reactors
A reproducible method for permeability measurements of tubular polymer membranes is developed and combined with a comprehensive review of hydrogen permeability data. Based on this analysis, a suitable tubular polymer membrane is identified for application in biological methanation within membrane reactors.
