Methane release from warming-induced hydrate dissociation in the West Svalbard continental margin: timing, rates, and geological controls

, 2013
Hundreds of plumes of methane bubbles, first observed in 2008, emanate from an area of the seabed off West Svalbard that has become 1°C warmer over the past 30 years. The distribution of the plumes, lying close to and upslope from the present upper limit

Mathematical Model and Simulation of Gas Hydrate Reservoir Decomposition by Depressurization Modèle mathématique et simulation de dépressurisation et de décompression d’un réservoir d’hydrates de méthane

Oil & Gas Science and Technology, 2012
The numerical model for the depressurization of methane hydrates in a confined reservoir is presented based on mass conservation in porous media, incorporating multiphase flow theory and kinetics of gas hydrate dissociation.

Assessment of Hydrate Prediction Software for MEG–Water–NaCl Systems

Asia-Pacific Journal of Chemical Engineering, EarlyView.
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.

Biotechnological aspects of sulfate reduction with methane as electron donor

, 2010
Biological sulfate reduction can be used for the removal and recovery of oxidized sulfur compounds and metals from waste streams. However, the costs of conventional electron donors, like hydrogen and ethanol, limit the application possibilities.

Large Submarine Landslides on Continental Slopes: Geohazards, Methane Release, and Climate Change [PDF]

, 2014
Submarine landslides on open continental slopes can be prodigious in scale. They are an important process for global sediment fluxes, and can generate very damaging tsunamis.

Effects of Mixed Surfactants on Methane Hydrate Formation and Dissociation

Chemical Engineering Transactions, 2016
Natural gas hydrates are ice-like crystalline and non-stoichiometric compounds formed by hydrogen bonds from water molecules when methane is trapped inside. Gas hydrates have received much attention not only as a new natural energy resource but also as a

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
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.

Hydrogen Permeability of Tubular Polymer Membranes for Biological Methanation Membrane Reactors

Journal of Applied Polymer Science, EarlyView.
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.

Modelling of gas hydrates in sedimentary systems : Methane hydrates impact on flow through porous media [PDF]

, 2022
In nature, gas hydrates exist in areas of permafrost and in shallow subsurface sediments at ocean depths of more than 300-500 metres. In terms of the Sustainable Development Goals (SDG) of the United Nations, better understanding of hydrates in nature ...
