NOVELTY - A gas separation process involves pressurizing a gas mixture; cooling the gas mixture feed to an operating pressure and operating temperature that are outside the first hydrate P-T stability envelope of first gas and inside the second hydrate P-T stability envelope of second gas; contacting the second gas with a water at the operating pressure and operating temperature to form a gas hydrate from the second gas and the water; separating the gas hydrate from the first gas; and placing the gas hydrate in heat transfer communication with the gas mixture feed to decompose the gas hydrate.    USE - Gas separation process for hydrocarbon processing applications, such as processing natural gas, and processing a synthesis gas.    ADVANTAGE - The resulting gas hydrate is readily separable from any remaining gas and stable for transport. The process reduces costly gas compression requirements for delivering hydrocarbon gas product to a high pressure gas pipeline system or other gas distribution system.    DETAILED DESCRIPTION - A gas separation process involves pressurizing a gas mixture including first gas having a first hydrate P-T stability envelope and a second gas having a second hydrate P-T stability envelope different from the first; cooling the gas mixture feed to an operating pressure and operating temperature that are outside the first hydrate P-T stability envelope and inside the second hydrate P-T stability envelope; contacting the second gas with a water at the operating pressure and operating temperature to form a gas hydrate from the second gas and the water; separating the gas hydrate from the first gas; and placing the gas hydrate in heat transfer communication with the gas mixture feed to decompose the gas hydrate. An INDEPENDENT CLAIM is included for gas transportation process comprising at a gas loading location, entraining a solid particle medium in a fluidizable mixture to form a fluidized mixture including an aqueous liquid feed and a hydrocarbon fluid feed, where the hydrocarbon liquid feed includes a hydrocarbon liquid and a hydrocarbon gas having a hydrate P-T stability envelope; cooling the fluidized mixture upon contact with a heat transfer surface; converting the hydrocarbon gas and the aqueous liquid feed to gas hydrate particles; forming a gas hydrate slurry; transporting the gas hydrate slurry to a gas off-loading location; at the gas off-loading location, heating the gas hydrate slurry to decompose the gas hydrate slurry to an aqueous liquid, the hydrocarbon liquid and the hydrocarbon gas; and separating the aqueous liquid, the hydrocarbon liquid and the hydrocarbon gas from one another.
