Description
- On certain zones from the sea and ocean's bottom take place leaks of gas, directed up-wards; gasses as helium, methane, butane, propane, carbon dioxide, and sulphur dioxide. These gasses reach the sea or ocean's surfaces, going further into the atmosphere, polluting it.
- The runnings are in the form of ventures jets, seepages or emissions of the entire surface of deposits of sediments with hydrates without lithological covering.
- The distribution of these runnings in the respective areas and their flows are very different. The sea depth, the flora and fauna, the water's chemical content and the variation of the sea bottom's profile are major factors which must be considered when a technology for the collection of these gasses is to be established.
- For the collection of respective gasses from the sea or ocean's bottom, accounting all the above-mentioned factors, two types of main technological diagram of collection of gasses are taken into consideration, as follows:
-
- A technological diagram for gas collection from the sea or ocean's bottom at a depth where a diver can reach in order to be able to do certain work under the water.
- A technological diagram for gas collection from the sea or ocean's bottom at a depth unreachable by a diver in order to be able to do certain work under the water.
- The diagram for depths reachable by a diver consists of some pyramidal rooms open at the bottom, rooms whose walls are provided with some holes at a short distance from their bottom. The rooms are seated, one by one, over each jet or gas emission from the sea or ocean's bottom. The top of each room is connected through a system of pipes set on the sea's bottom with a gas separator placed somewhere at a depth not too far below the sea's level, in water or on the shore. The discharge conduit of each room is provided with a gas detector, which determines the presence or absence of the gas inside the conduit; the same conduits are also provided with a valve.
- The gas collection with this diagram is realized as follows: the jets or gas emissions captured inside the rooms are activated by the sea's water, which is running from the sea's bottom into the rooms through the wall's holes and conduits towards a separator placed somewhere below the sea's level. The running is possible due to the level difference between the water from inside the conical rooms and the gas separator according to the vessels communication principle. The process is continuous and takes place as long as the jets and emission do; process detected at each room, with its detector, as shown above.
- If the detector shows no gas, the diver descends in the water and closes the afferent room's valve. It will continue to do so until the jets or emissions are exhausted or until the gas collection process is no longer justifiable. At the end of collection, the entire apparatus can be recuperated. The diagram can be extended over a large area of gas collection.
- The diagram for collection in depths unreachable by divers to do certain operation on the sea or ocean's bottom is similar to the one mentioned above and works under the same principle, with one following exception: the diagram is realized on a metallic platform, which is launched from the sea surface to the sea's bottom by a steel cable connected to the platform's four corners. The diagram collection is connected to the gas separator, which is placed somewhere below sea level, by a conduit to which one or more diagrams or collection blocks can be connected. The respective conduit, in its way towards the shown separator, is sustained in a vertical position by a steel cable, which also serves as the anchor to a specific apparatus for gas extraction found on the sea or ocean surface. Each platform is provided with some propellers that allow the horizontal movement of platform or block in a desired location.
- Each diagram has a single valve placed on the diagram's connecting conduit, with the conduit, which goes to the separator.
- An example of realization of principle diagram one for each of the two versions presented above is further presented, as shown in
