Empirical and Numerical Evaluation of Mechanisms in Gas Production from CH4-Hydrates: Emphasis on Kinetics, Electrical Resistivity, Depressurization and CO2-CH4 Exchange
(Doctoral thesis, 2013-12-13)Focus is shifted towards renewable energy and sources of natural gas as the demand for cleaner energy continues to increase with global awareness on anthropogenic climate change. Methane (CH4) provides advantages such as ... -
An Experimental Study of Methane Hydrate Growth and Dissociation in Porous Media
(Master thesis, 2015-06-01)Natural gas hydrate (NGH) is a solid phase consisting of water and natural gas. NGH represents a justified vast global energy resource, and is widespread in on-shore artic and sub-seafloor environments. Due to the worlds ... -
New hydrate risk evaluation for processing and transport of natural gas containing water and impurities
(Master thesis, 2014-10-16)The growth of natural gas transport by pipeline has led to the establishment of a large network of pipelines throughout the world [1]. Transport of natural gas through a network of pipelines is a challenging issue, mainly ... -
Numerical Investigation of Natural Gas Hydrate Agglomeration and Deposition in High Water Cut Pipeline Systems
(Master thesis, 2018-06-20)The phenomena of gas hydrate plugging constitute a well known problem in the petroleum production and transport industries. Nevertheless, this issue is still not fully understood, especially for high water cut systems. For ... -
Particle size distribution of methane hydrates and particle growth using a CFD-PBM model
(Master thesis, 2018-08-30)Gas hydrates are solid crystalline compounds that contain water and gas molecules, and can be considered to be a natural occurring phenomena located in enormous amounts around the world. Particle growth and agglomeration ... -
Pore-scale investigation of methane hydrate phase transitions and growth rates in synthetic porous media
(Master thesis, 2018-06-20)A growing demand for energy and natural gas in particular, makes methane gas hydrates a potential target to supplement natural gas production from conventional resources. Several pilot projects have proven the feasibility ... -
Reactive transport modelling of hydrate phase transition dynamics in porous media
(Doctoral thesis, 2015-03-27)Gas hydrate is believed to be so abundant in nature that some estimates suggest it contains more than two times equivalent energy of the whole fossil fuels on Earth. Besides, reservoir hydrates have other important aspects ...
