Abstract
The methods and apparatus for transporting compressed gas includes a gas storage system having a plurality of pipes connected by a manifold whereby the gas storage system is designed to operate in the pressure range of the minimum compressibility factor for a given composition of gas. A displacement fluid may be used to load or offload the gas from the gas storage system. A vessel including a preferred gas storage system may also include pumping equipment for handling the displacement fluid and provide storage for some or all of the fluid needed to load or unload the vessel.
Claims22
A method for loading gas into a plurality of containers for storage at a desired temperature and pressure comprising:
- filling a storage container with a liquid at the desired storage temperature and pressurizing it to the desired storage pressure;
- processing a gas so that the gas is at the storage temperature and pressure;
- and
- injecting the processed gas into the storage container while removing the liquid from the storage container such that the storage conditions are maintained within a range that prevents thermally shocking the storage container, wherein the storage conditions comprise a temperature of 0° F. or lower.
A system for the transport of gas at pre-selected storage conditions comprising:
- a vessel comprising a plurality of storage containers;
- a liquid source adapted to maintain a supply of liquid at the storage temperature;
- and
- a gas source adapted to supply gas at the storage conditions;
- wherein as the storage containers are filled with gas, liquid is displaced from the storage containers so as to prevent thermally shocking the storage containers, wherein the storage conditions comprise a temperature of 0° F. or lower.
A method for unloading gas from a container disposed on a vessel where the gas is stored at a desired set of storage conditions comprising:
- injecting the container with a liquid stored on the vessel at the desired storage temperature;
- and
- removing the gas from the container so as to substantially maintain the storage conditions within the container in order to prevent thermally shocking the storage container where the storage conditions comprise a temperature of 0° F. or lower.
