Abstract
A gas containment system can include a gas barrier layer forming a capsule. The gas barrier layer can be made up of a particulate swelling clay, a non-swelling particulate material mixed with the particulate swelling clay, water, and a water-soluble polyol. The water can hydrate the particulate swelling clay and form a continuous liquid phase in the gas barrier layer. The water-soluble polyol can be dissolved in the water. The gas containment system can further include a gas retained inside the capsule.
Claims28
A gas containment system comprising:
- a gas barrier layer forming a capsule, the gas barrier layer comprising:
- a particulate swelling clay;
- a non-swelling particulate material mixed with the particulate swelling clay;
- water hydrating the particulate swelling clay and forming a continuous liquid phase in the gas barrier layer;
- and
- a water-soluble polyol dissolved in the water;
- and
- a gas retained inside the capsule.
A method of containing a gas within an enclosed volume comprising:
- forming a capsule surrounding the enclosed volume, said capsule being formed from clay amended soil hydrated by a solution of water and a water-soluble polyol;
- providing a gas within the enclosed volume;
- and
- maintaining a hydraulic conductivity of the capsule such that the capsule exhibits diffusion controlled gas transport.
A gas containment system comprising:
- a gas barrier layer forming a capsule, the gas barrier layer comprising:
- a particulate swelling clay;
- a non-swelling particulate material mixed with the particulate swelling clay;
- and
- glycerin, wherein the gas barrier layer is substantially devoid of water;
- and
- a gas retained inside the capsule.
