Abstract: For storage of natural gas at pressures over 1,000 psia, it is advantageous to add to natural gas an additive which is a C2 or C3 hydrocarbon compound, or a mixture of such hydrocarbon compounds. Above a lower limit (which varies with the additive being added and the pressure), there is a decrease in the amount of power needed to compress the mixture. For storage or pipeline transportation of natural gas at pressures over 800 psia, it is advantageous to add ammonia to the natural gas, in an amount such that the ammonia does not create a liquid phase at the temperature and pressure used. The ammonia-natural gas mixture can be compressed or pumped with a lower energy expenditure than would be needed for an equivalent volume of natural gas alone. When more than 4% by volume of ammonia is present, the pumping through pipelines is also aided by the refrigerant effect of the ammonia, which reduces the temperature of the gas being transported.

Abstract: A method is disclosed for unloading a plurality of containers containing pressurized liquefied gas in which the liquefied gas has a temperature above −112° C. A pressurized displacement liquid is fed to a first of the plurality of containers to discharge the pressurized liquefied gas therefrom.

As the displacement liquid is removed from the first container, the space caused by the removal of the displacement liquid is filled with a vapor at a lower pressure than the pressure of displacement liquid. Fluid communication between the first second containers is then severed and the above steps are repeated for all containers in succession, except that for the last container in the series the displacement liquid is pumped therefrom to an auxiliary container for storage rather than to another container.
