US Patent 4,199,533, University of Southern California (Los Angeles, CA)
BACKGROUND OF THE INVENTION
Currently, there is an unprecedented global demand for energy for industrial and economic development in several high growth regions of the world, and this demand has exceeded in many instances the total capacity of production of fossil-derived energy sources including crude, natural gas, and coal.
When alternative energy sources are factored into the energy supply/demand equilibrium, that is, nuclear, biomass, wind, solar, geothermal and hydro derived energy pools, it is still possible that demand exceeds production capacity. Fossil energy sources are now increasingly explored and mined in far-flung regions that is substantially further away from its demand markets, and in some circumstances, these energy sources are discovered in regions where overall operating environments may be difficult. In the field of natural gas exploration and development, substantial technology has been developed for gas liquefaction to convert natural gas into denser liquefied natural gas (LNG), or directly into hydrocarbons that is easier to transport using marine vessels.
These hydrocarbons may include methanol, light olefins, gasoline, diesel, heavy wax fuels etc. Upstream technologies developed for the oil industry include marine vessels (offshore oil rigs, submersible platforms, etc.) that can drill to depths that was not possible just one decade ago, and various downstream technologies such as dedicated FPSO (floating production storage and offloading) vessels that can perform a variety of refinery and storage functions.
While the energy environment remains competitive and at times challenging, great potential can be found in still unexplored areas of the world include the Arctic/polar regions where undiscovered oil and gas reserves are estimated at 25% of total world supplies. Significant developments have also been made in the areas of tar sands and shale oil recovery to yield syncrude (synthetic crude).
Additionally, a gradual realization of an apparent acceleration of rising temperatures in almost every major part of the world have convinced many that the continued use and subsequent pollution of heat trapping gases such as carbon dioxide (CO2) cannot be reasonably sustained without dramatic implementation of technologies in the area of environmental regulation, emissions control, carbon sequestration/storage, and simply using fuels that are derived from renewable resources.
It is now estimated that a small elevation in global median temperatures can trigger varying amounts of flooding and sea level readjustments especially to coastal regions, and with large number of urban population centers also located at these places, along with their industrial infrastructure including power generation, transport, factories and manufacturing plants, this presents a potentially massive shift in locating these critical facets of the industrialized states to locations where the mentioned effects are less pronounced.
Marine vessels ranging from container ships that can travel between continents and vast distances to maritime vessels that are simply moored or anchored to body of water, such as storage platforms or ships that can function of depositories for energy assets such as crude oil, or to conduct drilling of energy reserves found deep within the depths of the sea. In addition to ships that either perform transportation of energy, there are vessels that can drill and extract energy, and further "production" vessels that can convert the extracted energy such as natural gas, into denser or more suitable forms, such as methanol, LNG, etc.

A plasma is a mixture of ions, electrons and neutral particles produced when stable molecules are dissociated (in this case by an electric arc). The electric arc is formed between two electrodes, the anode (+) and cathode (-). Variations of a plasma-producing device may be in the electrode assembly, the type of flow gas (air, argon, carbon dioxide etc.), use of plasma arc torches, and their power supply requirements (AC versus DC current etc).
Gasification or pyrolysis
Refers to any thermal heating action or process acting on a material to yield gas blend containing elements originally present in the material prior to thermal heating action. In materials containing carbon and moisture, carbon monoxide and hydrogen is produced from this thermal heating action. This gas mixture of carbon monoxide (CO), hydrogen (H2) (along with other gases such as carbon dioxide etc.) is commonly called "Syngas". Generally, a carbonaceous material/feedstock can be converted by thermal means into a syngas blend. Gasification/pyrolysis can be interchangeably used to describe the process of converting the feedstock into Syngas.

SUMMARY OF THE INVENTION
Process of manufacture and distribution of a hydrocarbon product to at least one remote site, using a marine vessel wherein manufacture and distribution are implemented onboard.
A marine vessel (such as a suitably adapted floatation vehicle) performs intake and loading of a carbonaceous feedstock up to a predetermined load tonnage, from a first remote site, which may be a port terminal facility, a second marine vessel, or a flotation terminal/structure such as an offshore platform, or a land-based/terrestrial facility. The feedstock may be pre-treated including reducing or increasing its moisture content, either by heat drying (reducing moisture), or fluid spraying or steaming (increasing moisture). The feedstock may also be reduced in physical size by means of a grinder device, or be pulverized into a suitable sieve size. The reduction of the feedstock will enlarge surface area that can be converted into the Syngas blend during conversion stage in the thermal conversion plant.
The pre-treated feedstock is then passed into the thermal conversion plant to allow for the feedstock to be thermally converted into a Syngas blend comprising CO and H2, however, the Syngas blend may further comprise of additional gases such as CO2 etc, depending on the proximate/ultimate analysis and composition of the feedstock used. (The present invention may use a mixture of different feedstock types depending on the location where the feedstock is collected for conversion).
The syngas blend may undergo a gas "clean-up" stage where the additional gases are removed to an acceptable level, and passed into the chemical reaction unit/plant, where the syngas is converted into a hydrocarbon product
The syngas is converted into the hydrocarbon product by ultraviolet irradiation in a suitable irradiation plant device.
The hydrocarbon product is then isolated, or collected for storage onboard the vessel, which is then subsequently delivered and distributed to a remote site. The marine vessel is simultaneously performing delivery of the predetermined product to a remote site while converting the carbonaceous feedstock into the said product using the onboard thermal conversion plant, the chemical reaction unit and the marine vessel's system.
