Clathrate hydrates, or gas clathrates, gas hydrates, clathrates, hydrates, etc., are crystalline water-based solids physically resembling ice, in which small non-polar molecules (typically gases) or polar molecules with large hydrophobic moieties are trapped inside "cages" of hydrogen bonded, frozen water molecules. In other words, clathrate hydrates are clathrate compounds in which the host molecule is water and the guest molecule is typically a gas or liquid. Without the support of the trapped molecules, the lattice structure of hydrate clathrates would collapse into conventional ice crystal structure or liquid water. Most low molecular weight gases, including O₂, H₂, N₂, CO₂, CH₄, H₂S, Ar, Kr, and Xe, as well as some higher hydrocarbons and freons, will form hydrates at suitable temperatures and pressures. Clathrate hydrates are not officially chemical compounds, as the sequestered molecules are never bonded to the lattice. The formation and decomposition of clathrate hydrates are first order phase transitions, not chemical reactions. Their detailed formation and decomposition mechanisms on a molecular level are still not well understood. Clathrate hydrates were first documented in 1810 by Sir Humphry Davy who found that water was a primary component of what was earlier thought to be solidified chlorine.

The present invention includes a method for inhibiting hydrate formation blockage in a flow line used to transport hydrocarbon containing fluids. Water is added to a hydrocarbon containing fluid to produce a water cut enhanced hydrocarbon containing fluid. Salt may be added to the hydrocarbon containing fluids as well. Hydrate formation blockage is inhibited from forming within the flow line by the addition of the water and / or the salt. Sufficient water may be added such that the hydrocarbon containing fluid is converted from a water in oil emulsion to a water continuous emulsion. A system for preventing the formation of hydrate blockage in conduits is also provided. The system includes a flow line for transporting a hydrocarbon containing fluid and a water injection conduit fluidly connected to the flow line to add water to the flow line to increase the water cut of a hydrocarbon containing fluid flowing through the flow line. A salt dispenser may also be included which is used to increase the salinity of the hydrocarbon containing fluid. The system may further include a water separator to separate hydrocarbons from water which receives fluids from the flow line. The flow line, water separator and water injection conduit may cooperate to form a loop wherein water from the flow line may be separated by the water separator and a portion of the separated water is delivered back to the water injection conduit to be reinjected into the flow line.

The present invention involves inhibiting clathrate hydrate formation by adding ionic liquids that are soluble in water. Properly tailored ionic liquids shift the hydrate-aqueous liquid-vapor equilibrium curve to a lower temperature and, at the same time, retard the hydrate formation by slowing down the hydrate nucleation rate. This dual function makes this type of inhibitors perform more effectively. The present invention is useful for the production, processing, and transportation in oil and gas industry, especially for deep-sea exploration and production where the operating temperature and pressure become in favor of hydrate formation.

A method and apparatus for controlling hydrogen gas storage in a clathrate hydrate structure through application of an electromagnetic field. The applied field can be used to control release of gas from the clathrate hydrate structure and / or uptake of gas into the clathrate hydrate structure. The electromagnetic field is arranged to promote “hopping” of gas molecules between and out of retaining pockets in the clathrate lattice by stimulating vibrations in the lattice that cause apertures into the retaining pockets to flex open. Advantageously, the electromagnetic field may have properties that are selected to promote an increase in the rate gas release or gas uptake without causing dissociation of the lattice. In this scenario, the invention can provide an energy-efficient, rechargeable on-demand supply system for any gas that can be retained within a clathrate hydrate structure.

Method for inhibiting hydrate formation
A method for inhibiting the formation of clathrate hydrates in a fluid having hydrate-forming constituents involves treating the fluid with an inhibitor comprising a substantially water soluble polymer having a polymer backbone with a pendant C1-C3 alkyl group; the polymer having an average molecular weight between about 1,000 and about 6,000,000. Preferably, the pendant alkyl group is a methyl group. The rate of nucleation, growth, and / or agglomeration of gas hydrate crystals in a petroleum fluid stream is reduced using the alkylated polymer backbone inhibitor, thereby inhibiting the formation of a hydrate blockage in the pipe conveying the petroleum fluid stream. Test results are disclosed which unexpectedly show that alkylating the polymer backbone with a methyl group will produce a subcooling for the alkylated polymer that is at least about 2 DEG F. (about 1.1 DEG C.) greater than its nonalkylated counterpart. The inhibitor can be used conveniently at low concentrations, for example in the range of from about 0.01% to about 5% by weight of the water present in the oil or gas stream, to effectively treat a petroleum fluid having a water phase.
