Abstract:
The invention provides a method and system for extracting stranded gas (such as natural gas or hydrogen) or a mixture of oil and natural gas from a subterranean environment such as beneath the ocean floor and converting it into a solid hydrate such as a clathrate featuring a) extracting stranded gas (such as natural gas or hydrogen) or a mixture of oil and natural gas; b) optionally separating the natural gas from the mixture of oil and natural gas in a first tank or vessel; c) transporting the stranded gas to a second tank or vessel; d) introducing sea water into the second tank or vessel; e) mixing the stranded gas and water to form a clathrate hydrate/water slurry; f) removing excess water from the clathrate hydrate slurry to form a solid comprising a clathrate hydrate; and g) processing the solid comprising a clathrate hydrate into a transportable form; and h) optionally collecting the gas into a transportable vessel.

Claim (Index 10):
The method according to  claim 6  wherein the mixing the natural gas and water to form a NGCH/water slurry comprises one or more methods selected from the group consisting of (i) spraying of a mist of water into a pocket of gas at the top of the tank or vessel, (ii) drawing natural gas from a gas pocket at the top and pumping it to the tank or vessel bottom where it is injected as fine bubbles that rise through the water in the tank or vessel, (iii) stirring and shearing the slurry that accumulates below the pocket of gas in order to break up the clathrate hydrate shells that form around gas bubbles, and (iv) pumping a mix of gas and sea water taken from within the tank or vessel into the center of two solid and closely spaced, counter-rotating plates with corrugated surfaces, in order to provide a high shear field and locally pulsating pressure that also breaks up any clathrate slurry shells forming around ellipsoidal gas bubbles.
