Title:
PROCEDURE AND APPARATUS FOR THE EXTRACTION OF METHANE GAS FROM THE SEA BOTTOM
Document Type and Number:
WIPO Patent Application WO2003102347
Kind Code:
A3
Abstract:
The present invention is referring to a procedure and an apparatus of extraction of methane gas from the bottom of the sea. The procedure 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.
