Sentences with phrase «co2 at high pressure»

CO2 at high pressure forms a liquid, then ultimately reacts with igneous rocks to form CaCO3.

Not exact matches

Since 1996, the Norwegian company Statoil has been stripping about a million tons of CO2 a year out of natural gas from the Sleipner West field under the North Sea and injecting it at high pressure into a saline aquifer.
In the right locations, CO2 injected into the ground at high pressure would react with those minerals to form stable carbonate rock.
Here, Siska Genbrugge removes the protective coating from a sculpture using a new dry ice blasting technique by which small pellets of frozen CO2 were targeted onto the coating at high pressure.
Note that a 2m tube of CO2 at 1 atmosphere pressure will be somewhat more absorptive than the same amount of CO2 spread over the depth of the atmosphere, since high pressure increases absorption.
The processes (absorption of light, collisional energy transfer and emission) can be separated because the average time that an isolated CO2 molecule takes before it emits a photon is much longer that the time for collisional de-excitation (~ tens of microseconds at atmospheric pressure, less, higher in the atmosphere).
Low atmospheric CO2 levels during the Permo - Carboniferous...... at a time when total atmospheric pressure was similar or slight higher than now.
CO2 also becomes a more effective greenhouse gas at higher atmospheric pressures (even if super-imposed upon several more bars of a non-greenhouse gas like N2 would generate a much stronger GHE by increasing absorption away from line centers).
It is reasonable to assume that human CO2 emissions will continue to grow at a slightly higher level than population, despite the fact that there is considerable pressure on fossil fuels (economic as well as environmental) and the carbon efficiency of all nations is continuously improving (especially in the developed nations).
Earth's mantle contains liquid CO2 under high pressure and emits CO2 to air in volcanic eruptions and in some volcanic xenoliths that spontaneously fracture at Earth's surface.
Bolin & Eriksson's «buffer» factor would give about 10 times higher CO2 concentration in air vs. sea water at about 0.0003 atmospheres CO2 partial pressure, increasing dramatically to an air / water CO2 partition coefficient of about 50:1 at a CO2 partial pressure of about 0.003 atmospheres (10 times the assumed pre-industrial level; Bacastow & Keeling, 1973; see Section 7 below for more on the «buffer» factor).
There are risks in geosequestration associated with the high vapour pressure of CO2 at the temperatures found in geological formations and with the high solubility of CO2 in groundwater.
I must confess I'm completely ignorant of the volumetric behavior of sea water at low temperatures, all my work with CO2 and sea water, and / or brine has been done at much higher temperature and pressure.
If the vapor pressure of a layer of CO2 at the surrounding temperature was higher than the ambient PARTIAL PRESSURE of CO2, the CO2 would continually pressure of a layer of CO2 at the surrounding temperature was higher than the ambient PARTIAL PRESSURE of CO2, the CO2 would continually PRESSURE of CO2, the CO2 would continually sublime.
If there were a CO2 greenhouse effect at 1 bar in Venus» atmosphere, then a person would expect to see a much higher temperature at this pressure.
So extra CO2 cools; this puts a twist on pressure broadening; the AGW view is that this shows CO2 will increase temp at higher temps and pressure and concentration; you seem to be saying the opposite; so I suppose you would be saying that an increase in CO2 mitigates the THS?
Therefore, by computing (or measuring) the absorption at sea level pressure, we are overestimating the absorption of the CO2 actually in place in the higher, lower - pressure parts of the atmosphere.
Hence, CO2 and water vapor must, in an equilibrium, produce about 33 ° C. However, at the top of Everest the temperature in the high summer climbing season is about -16 and in winters falls to about -37 ° C, yet the CO2 pressure is only about a third of that at sea level.
