International Classification:

E02F007/00

US Classification:

299/008000, 299/009000

Abstract:

The present invention is referring to a procedure and a apparatus of extraction of methane gas from the bottom of the sea, consigned to the extraction of methane gas from marine sediments found in the sea's and ocean's depthless and with which came to produce in the end, methane liquefied gas. The procedure, in accordance with the invention consists of lowering a take out enclosure to a depth of over 500 m., followed by a take out of a quantity of cryohydrate sediment from the bottom of the sea and the elevation of enclosure until is reached a level at which the water pressure and its temperature create conditions which allowed the beginning of a process of releasing of methane gas from cryohydrate crystals. The following operation is the releasing of methane from the entire quantity of take out cryohydrate, methane that is collected in a room from where is raised through a tube and captured into an enclosure and then liquefied. The remaining sediments without methane are returned to the ocean's floor by gravity. The apparatus, conform to the invention, is composed of some guiding arms B positioned crosswise, and on which a platform A is sitting and from a central anchor C at which cylindrical corp are assembled by superior ends of some portion c of the mentioned arms B, some collection cages D being suspended of arms B by some ropes and help, and anchor C in which is incorporated an axial-radial bearing being connected by an intermediary rope at the sea bottom.

Abstract:

The present invention is referring to a procedure and an apparatus for collection of free methane gas from the sea bottom, destined to collect and liquefy the methane gas liberated from metastabile deposits of hydrate methane situated on the seas or oceans bottom. The procedure, in a first version of realization, according to the invention, includes the collection of free methane gas from the sea bottom in a mixture with the sea water and directing this mixture up wards to the surface, where is taking place a gravitational distribution of it on a big surface, for permitting the methane gas to separate from water. The humid captured methane gas is cooled to produce the condensation of the last seawater fraction after, which is done its cooling to the required temperature for passing from the gaseous state into the liquid state. The apparatus, in its first version of realization, according to the invention, is made from some guiding arms A on which is sitting an intermediary platform B, destined to support some electrical reversible trolleys D and E, used for the displacement on radial and vertically direction of some telescopic conduit and of some collectors K, of some electrical reversible and double trolleys F for driving some separators L and of a flexible conduit on radial direction, as well and of some electrical reversible and double trolleys G used for some lateral anchors maneuver. On the vertical axis of apparatus is found a central anchor stiffed by a hoist . The ends of arms A are provided with some propellers and for ensemble's rotation. On platform B and C are positioned a humidity extractor M from which the condense is eliminated, a gas methane liquefactor N and this is connected with a storage tank O. A nitrogen compressor discharged the arrived nitrogen through laminate valve f towards a tank of liquid nitrogen P

Abstract:

The present invention refers to a gas collection system from the sea bottom's vents, used to collect gaseous emissions found on the sea or ocean's bottom, from the entire area of sediments deposits with hydrates without lithologic coverage. The system, in a first version, is destined to depths accessible to a diver and consists of some conical rooms connected at their superior part with some conduits , to some collecting conduits , further connected to an other conduit which will lead the mixture of sea's water and gas to a gas separator station, not shown, located somewhere below the sea level, in water or on the shore. Each connection conduit with collecting conduit is provided with a valve and before it, with a gas detector . The system, in a second version, is destined to depths inaccessible to divers and consists of rooms , open at the bottom, provided with entrance holes b and connected at its superior part with conduits , which are connected with collectors , rooms ′ and conduits ′ and ′. These are installed on a horizontal platform provided with some legs c, with some steel cable and with a conduit ′, for connection to the gas separator, platform is provided at its corners with a reversible propeller . The rooms are provided with some legs a and some entrance holes b, placed on the lateral walls, near their base. The platform may have in horizontal plan a trapeze shape in order to be installed in concentric circles. Each platform is being connected through some radial conduit ′ to a major conduit , which leads to the separation station.
