• nitrogen
  • The filling gas within the discharge tube consists of around 10-20% carbon dioxide (CO 2), around 10-20% nitrogen (N 2), a few percent hydrogen (H 2) and/or xenon (Xe) (usually only used in a sealed tube), and the remainder of the gas mixture helium (He). (wikipedia.org)
  • emission
  • Also for meeting higher concentration levels, carbon dioxide removal is increasingly considered to be crucial as it provides the only possibility to fill the gap between needed reductions to meet mitigation targets and global emission trends. (wikipedia.org)
  • gaseous
  • In CO2 snow cleaning, compressed liquid or gaseous carbon dioxide is expelled from a nozzle, condensing into a mixture of solid particles and gas, which impact the surface to be cleaned. (wikipedia.org)
  • emit
  • The Intergovernmental Panel on Climate Change (IPCC) calculated projected temperature changes for various scenarios in 2007 and researchers at the Max Planck Institute for Meteorology in Hamburg have now gone one step further: they have developed a new model that specifies the maximum volumes of carbon dioxide that humans may emit to remain below the critical threshold for climate warming of two degrees Celsius.

  • processes
  • Hoff and his colleagues at SINTEF are developing chemical scrubbing processes for capturing carbon dioxide, the greenhouse gas that is spewed out by factories and as flue gases from coal and gas-fired power stations. (innovations-report.com)
  • Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in bread, beer and wine making. (wikipedia.org)
  • Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes. (wikipedia.org)
  • carbohydrate
  • Almost all other organisms depend on carbohydrate derived from photosynthesis as their primary source of energy and carbon compounds. (wikipedia.org)
  • climate change
  • The final possibility is qualitatively compatible with both 'consensus' views of climate change and the opinions of those who are more impressed with the manifestly adverse consequences of carbon-mitigation to human reproduction and survival. (repec.org)
  • reservoir
  • Carbon dioxide (CO2) flooding is a process whereby carbon dioxide is injected into an oil reservoir in order to increase output when extracting oil. (wikipedia.org)
  • It should also be noted that carbon dioxide flooding is not affected by the lithology of the reservoir area, but simply by the reservoir porosity and permeability, so that it is viable in both sandstone and carbonate reservoirs. (wikipedia.org)
  • To ensure that the Dupuy Formation was suitable for underground injection of reservoir carbon dioxide, the Gorgon Joint Venture undertook additional drilling, well tests, and seismic surveys prior to making the final investment decision. (wikipedia.org)
  • refrigerant
  • Carbon dioxide is used as a refrigerant, in fire extinguishers , for inflating life rafts and life jackets, blasting coal , foaming rubber and plastics, promoting the growth of plants in greenhouses, immobilizing animals before slaughter, and in carbonated beverages. (britannica.com)
  • Liquid
  • at −23 to −12 °C (−10 to 10 °F). By the mid-20th century, most carbon dioxide was sold as the liquid. (britannica.com)
  • Using water, it is a liquid/solid reaction as shown here: CaO(s) + H2O(l) → Ca(OH)2(s) ΔH° = -64.5 kJ/mol Other strong bases such as soda lime, sodium hydroxide, potassium hydroxide, and lithium hydroxide are able to remove carbon dioxide by chemically reacting with it. (wikipedia.org)
  • If the temperature and pressure are both increased from STP to be at or above the critical point for carbon dioxide, it can adopt properties midway between a gas and a liquid. (wikipedia.org)
  • atoms
  • The resulting hot helium atoms must be cooled in order to sustain the ability to produce a population inversion in the carbon dioxide molecules. (wikipedia.org)
  • combustion
  • Carbon dioxide was recognized as a gas different from others early in the 17th century by a Belgian chemist, Jan Baptista van Helmont , who observed it as a product of both fermentation and combustion. (britannica.com)
  • Ignited magnesium continues to burn in carbon dioxide, but the gas does not support the combustion of most materials. (britannica.com)
  • forests
  • To do this, the scientists incorporated into their calculations data relating to the carbon cycle, namely the volume of carbon dioxide absorbed and released by the oceans and forests. (redorbit.com)
  • Roughly half of the carbon is re-absorbed by forests and the ocean, a process that is not well understood. (yahoo.com)
  • capture and storage
  • A new project out of the UK promises to forever revolutionize the way we approach carbon capture and storage. (earthtechling.com)
  • Swedish researchers say bioenergy with carbon capture and storage can turn around the global warming trend eventually even if we miss near-term targets. (earthtechling.com)
  • Among such technologies are bio-energy with carbon capture and storage, biochar, ocean fertilization, enhanced weathering, and direct air capture when combined with storage. (wikipedia.org)
  • It is regarded by some as a form of climate engineering, while other commentators describe it as a form of carbon capture and storage or extreme mitigation. (wikipedia.org)
  • important
  • Carbon dioxide is an important input in food processing and retailers are working hard in conjunction with their suppliers to ensure food availability is maintained. (telegraph.co.uk)
  • primary
  • When a reservoir's pressure is depleted through primary and secondary production, carbon dioxide flooding can be an ideal tertiary recovery method. (wikipedia.org)
  • metals
  • Carbon dioxide snow cleaning has been used to remove particles and organic residues from metals, polymers, ceramics, glasses, and other materials, and from surfaces including hard drives and optical surfaces. (wikipedia.org)
  • removal
  • Anesthesia machines which provide life support and inhaled agents during surgery typically employ a closed circuit necessitating the removal of carbon dioxide exhaled by the patient. (wikipedia.org)
  • The regenerative carbon dioxide removal system (RCRS) on the space shuttle orbiter used a two-bed system that provided continuous removal of carbon dioxide without expendable products. (wikipedia.org)
  • The use of extracorporeal carbon dioxide removal is currently considered experimental, but it has been studied in a number of situations, specifically severe exacerbations of chronic obstructive pulmonary disease and in adult respiratory distress syndrome where conventional mechanical ventilation would cause excessive lung damage.
