Abstract
A method for the production of the natural gas hydrate characterized by the steps of: combining natural gas and water to form a natural-gas water system and an agent adapted to reduce the natural gas-water interfacial tension to form a natural-gas water-agent system, allowing the natural gas-water-agent system to reach equilibrium at elevated pressure and ambient temperature and reducing the temperature of the natural gas-water-agent system to initiate the formation of the natural gas hydrate.
Claims22
A method for the production of a natural gas hydrate characterised by the steps of:
- pre-mixing natural gas and water and an agent adapted to reduce the natural gas-water interfacial tension to form a natural-gas water-agent system;
- allowing the natural gas-water-agent system to reach equilibrium at elevated pressure and ambient temperature;
- and,
- after the natural gas-water-agent system has reached equilibrium at elevated pressure and ambient temperature, reducing the temperature of the natural gas-water-agent system to initiate the formation of the natural gas hydrate.
