Diagrams for collection of gas from ventures from the sea's bottom

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 1 connected at their superior part with some conduits 2 , to some collecting conduits 3 , further connected to an other conduit 4 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 2 with collecting conduit 3 is provided with a valve 5 and before it, with a gas detector 6 . The system, in a second version, is destined to depths inaccessible to divers and consists of rooms 1′ , open at the bottom, provided with entrance holes b and connected at its superior part with conduits 2′ , which are connected with collectors 3′ , rooms 1 ′ and conduits 2 ′ and 3 ′. These are installed on a horizontal platform 7 provided with some legs c, with some steel cable 8 and with a conduit 4 ′, for connection to the gas separator, platform 7 is provided at its corners with a reversible propeller 9 . The rooms 1 are provided with some legs a and some entrance holes b, placed on the lateral walls, near their base. The platform 7 may have in horizontal plan a trapeze shape in order to be installed in concentric circles. Each platform 7 is being connected through some radial conduit 4 ′ to a major conduit 10 , which leads to the separation station.

1 . System of gas collection from the sea bottom's ventures, in a first version destined to the depths accessible to a diver, consisting of conical rooms  1 , connected at its superior part with some conduits  2  to some collecting conduits  3  jointed further to an other conduit  4  which drives the sea water and gas mixture to a station of gas separation, not shown, located somewhere below the sea level, in water or on the shore, each connection of conduit  2  with collecting conduit  3  being provided with a valve  5  and before it, with a gas detector  6 .  
   
   
       2 . System of gas collection from sea bottom's vents, in a second version, destined to depths un-accessible to a diver, consisting of conical rooms  1 ′, open at the bottom, provided with holes b and connected at their superior part to conduits  2 ′ which are connected to collector  3 ′. The rooms  1 ′ and the conduit  2 ′ and  3 ′ are installed on a horizontal platform  7 , provided with some legs c, with some steel cables  8  and with a conduit  4 ′, for connection with the gas separator. Platform  7  is equipped with a reversible propeller  9  placed at its four corners.  
   
   
       3 . System of gas collection from sea bottom's vents, according to  claim 1 , characterized as follows: rooms  1  are open at their inferior part, are sitting on some legs a of connection and are provided with some entrance holes b, in the lateral walls, towards the bottom.  
   
   
       4 . A gas collection system from sea bottom's vents, according to  claim 2 , characterized by that the platform  7  may have in horizontal plan a trapeze shape in order to be placed so as to fit in an concentric circle, each of the platform  7  being connected through some radial pipes  4 ′ to a main conduit  10 , which leads to the gas separation station.
