Web28 sep. 2024 · Mais cette industrie se heurte à un obstacle : les hydrates de méthane. Ces composés solides, en fait des molécules d’eau solidarisées en une sorte de cage autour d’une molécule de méthane, se forment aux alentours de 4°C et 80 bars de pression, dans les conditions des pipelines profonds… si bien qu’ils finissent parfois par s ... Web14 mrt. 2024 · The hydrocarbons that were released ended up forming methane clathrate hydrates with surrounding water vapors. Unfortunately, the accumulation of methane clathrate hydrates blocked the well caps and prevented a 100-ton containment structure from being sealed after the blowout ( Figure 1 ). Figure 1.
WebGas hydrates consist of molecules of natural gas (the chief constituent of natural gas; methane) enclosed within a solid lattice of water molecules. When brought to the earth's surface, one cubic meter of gas hydrate releases 164 cubic meters of natural gas. Gas hydrate deposits are found wherever methane occurs in the presence of water under ...
