What is hydrate buildup on an oil rig?
A VERY timely question. The formation of gas hydrates is quite complex. Fortunately, there is a Wikipedia link, with (as usual) excellent information. Formation of these crystals requires the presence of methane, high pressures and cold conditions, all of which have been met by the blown out well. The ocean floor at 5,000 ft is approximately 42 degrees. These crystals will clog pipelines. Apparently this is what happen when the cofferdam failed to work. One very interesting fact is that the methane hydrates formed in the dome of the cofferdam and added bouyancy. A redesigned cofferdam might be heavier. Hydrates have been a problem in Canada and Alaska wells and pipelines with the usual treatments of lower pressures, heat and methanol treatments. See related link - particularly about the most recent experience with the Deepwater Horizon.
What is the ingredients of earth gas?
Earth gas / Natural gas consists of methane with 0-20% higher hydrocarbons (primarily ethane). Earth gas also found correlated with other hydrocarbon fuel (methane clathrates), an important fuel source and a major feedstock for fertilizers.
How many valence electron does methane has?
4 valence electrons are present in methane
How can you reduce the impact of burning methane on global warming?
We can stop burning methane. Actually burning methane is better than letting it escape into the atmosphere. Methane, when burnt, emits carbon dioxide, a powerful greenhouse gas, but methane, when released into the air, is twenty-one times more dangerous.
Most oceanic gas hydrates form when?
bacteria break down organic matter in seafloor sediments
What conditions are most favorable for making methane hydrates?
Conditions most favorable for making methane hydrates are low temperatures (below 0°C) and high pressure (typically found in deep ocean sediments). Methane hydrates form when methane gas and water molecules combine under these conditions to create a solid, ice-like structure. These conditions are often found in deep-sea environments where methane-producing microorganisms thrive.
Why are Methane hydrates bad for boats?
Methane hydrates are not inherently bad for boats. However, if methane is released from hydrates in large quantities in the water, it can reduce the water density and potentially lead to buoyancy issues for boats. Methane hydrates can also contribute to the formation of gas seeps, which can be hazardous for boats navigating in those areas.
How many methane may be locked up in sediments containing gas hydrates?
It is estimated that vast amounts of methane, potentially around 1,000 to 10,000 gigatons, may be locked up in sediments containing gas hydrates. These hydrates are found primarily in marine sediments and permafrost regions, where specific temperature and pressure conditions allow methane to form solid hydrates. This significant reservoir of methane has implications for both energy resources and climate change, as the release of methane could contribute to greenhouse gas emissions.
What is the new energy source found in the ocean that is costly to get?
Ocean Thermal power.Ocean Wave power.
What potential benefits can methane hydrates have?
is the gas methae (hydrates)ba potetial energy source?
True or false Methane hydrates form within the ocean and are not expensive to obtain?
True and False. Methane hydrates form mostly under permafrost and ice caps, but some form in the ocean.Methane hydrates are expensive to obtain.
Why are methane hydrates so difficult to extract from the seafloor?
Methane hydrates are so difficult to extract from the sea floor because if methane gas escapes directly to the atmosphere, as a byproduct of extraction, an earthquake or warming ocean waters, the consequences could be dire. 3000 times more methane exists in hydrate deposits than in the atmosphere. Releasing even a fraction of this amount would amplify global warming. This is from Cha Cha!
Are methane hydrates inexhaustible?
Methane hydrates are not inexhaustible; they are a finite resource found in specific geological conditions, primarily in ocean sediments and permafrost. While they represent a significant potential energy source, their extraction and utilization are limited by technological, environmental, and economic factors. Additionally, the stability of methane hydrates can be affected by climate change, which may alter their availability over time. Therefore, while they are abundant in certain regions, they are not an infinite resource.
Why are methane hydrates dangerous to ships?
Methane hydrates can be dangerous to ships because they are often found in deep-sea environments and can destabilize during changes in pressure or temperature, leading to sudden releases of methane gas. This release can create large gas bubbles that can reduce buoyancy and stability of a vessel, potentially causing it to sink. Additionally, the flammable nature of methane poses a significant fire hazard if ignited. The unpredictable nature of these hydrates makes navigating areas where they are present particularly risky for maritime operations.
Methane hydrates form within the ocean and are not expensive to obtain?
Methane hydrates are trapped in ice crystals under the seafloor and deep within permafrost on land, making extraction challenging and expensive. The process involves drilling, heating, and depressurizing to release methane, which also poses environmental risks such as methane leakage and seabed instability. Due to the complex and costly extraction methods, methane hydrates are not currently a viable commercial energy source.
Definition of methane hydrates?
Methane hydrates are ice-like compounds composed of water molecules containing trapped methane gas. They form under specific conditions of low temperature and high pressure, typically found in deep-sea sediments or permafrost regions. Methane hydrates have garnered interest as a potential future energy source but also pose environmental risks due to the potent greenhouse gas methane being released if destabilized.
How much methane may be locked up in sediments containg gas hydrates?
It is estimated that there may be more methane locked up in sediments containing gas hydrates than all other fossil fuel reserves combined. The total global potential of methane in gas hydrates is uncertain but could be in the range of hundreds of trillion cubic meters. Unlocking this methane poses challenges due to technical, environmental, and economic factors.
