Modelling gas hydrate formation
Transcript of Modelling gas hydrate formation
Modelling gashydrate formation
It burns = $ (! ?)
25 times stronger
green house gas
Sulfide reduction zone
Main zone of methane production
Gas hydrate formation
The flux and concentration of organic matter is controlled by the fluxes of IRD, clay and the organic productivity
Organic material is broken down by oxidation using O
Organic material are boken down by sulfate reduction
2C(H O) + SO =>2HCO +H S
POC loss within this zone can be solved by
f =exp(3.2*age -3.2*(t +age ) )
But in this is neglected, as the oxidized zone is thin and the measured TOC i assumed to be from bellow this zone
Age of organic matter bellow the oxidized zone
Organic matter are broken down into CO and H by fermentation methane are then formed by methanogenesis
CO + 4H => CH +2H O
The fraction of organic matter converted into methane are calculated by
Age of organic matter bellow the bioturbated zone
Disolved inorganic carbon
