A system for converting light hydrocarbons to heavier hydrocarbons having a synthesis gas production unit and a hydrocarbon synthesis unit. For one application the synthesis gas production unit includes a turbine unit with a compression section, an autothermal reformer fluidly coupled to the compression section for producing synthesis gas and combusting at least a portion the gas therein, and an expansion section of the turbine unit fluidly coupled to the autothermal reformer for developing energy from the output of the autothermal reformer. A water separation unit is preferably fluidly coupled to the synthesis gas production unit for removing water from the synthesis gas. The water is directed to an oxygen/hydrogen separator to produce oxygen and hydrogen. Another water separation unit may also be coupled to the output from the hydrocarbon synthesis unit for removing water from the heavier hydrocarbons and directing the water to the oxygen/hydrogen separator.

System for converting light hydrocarbons to heavier hydrocarbons with separation of water into oxygen and hydrogen

A synthesis gas production system (302) incudes a gas turbine (310) having a compressor (312) with an autothermal reformer (308) between the compressor (312) and the turbine (314). The system (302) may include a separator (326) for removing a portion of the mass exiting the compressor (312) prior to its delivery to the autothermal reformer (308). Gaseous light hydrocarbons are delivered to the autothermal reformer (308) through conduit (330) and may be selectively controlled with a valve (331). Synthesis gas production system (302) may be used with a methanol process, ammonia process, a Fischer-Tropsch process (304), or other process involving synthesis gas.

A system for recovering liquid hydrocarbons from hydrates on an ocean floor includes a vessel, a positioning subsystem coupled to the vessel for holding the vessel in a desired location over a hydrate formation, a hydrate recovery subsystem coupled to the vessel for delivering hydrates from an ocean floor to the vessel and separating gas from hydrates removed from an ocean floor, a gas conversion subsystem coupled to the hydrate recovery subsystem for converting gas to liquids, and a storage and removal subsystem. Excess energy from the gas conversion subsystem is used elsewhere in the system. A method of recovering hydrates from an ocean floor is also provided.
