The change of atmospheric pressure with altitude can be obtained from this equation: [2] P a = 0.9877 a {\displaystyle P_{a}=0.9877^{a}} Given an atmospheric pollutant concentration at an atmospheric pressure of 1 atmosphere (i.e., at sea level altitude), the concentration at other altitudes can be obtained from this equation:
The Boudouard reaction, named after Octave Leopold Boudouard, is the redox reaction of a chemical equilibrium mixture of carbon monoxide and carbon dioxide at a given temperature.
TCRE is modeled using climate models that simulate carbon emissions by increasing CO 2 emissions by 1% per year from pre-industrial levels until the concentration of CO 2 in the atmosphere is doubled (2 x CO 2) or quadrupled (4 x CO 2).
An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
The following table lists the Van der Waals constants (from the Van der Waals equation) for a number of common gases and volatile liquids. [ 1 ] To convert from L 2 b a r / m o l 2 {\displaystyle \mathrm {L^{2}bar/mol^{2}} } to L 2 k P a / m o l 2 {\displaystyle \mathrm {L^{2}kPa/mol^{2}} } , multiply by 100.
To convert heat values to joules per mole values, multiply by 44.095 g/mol. To convert densities to moles per liter, multiply by 22.678 cm 3 mol/(L·g). Data obtained from CRC Handbook of Chemistry and Physics , 44th ed. pages 2560–2561, except for critical temperature line (31.1 °C) and temperatures −30 °C and below, which are taken from ...
Environmentally beneficial, low-cost substitutes for rigid thermoplastic and fired ceramic are made using s CO 2 as a chemical reagent.The s CO 2 in these processes is reacted with the alkaline components of fully hardened hydraulic cement or gypsum plaster to form various carbonates. [12]
The UK government has estimated social cost of carbon since 2002, when a Government Economic Service working paper Estimating the social cost of carbon emissions suggested £19/tCO2 within a range of £10 to £38/tCO2. This cost was set to rise at a rate of £0.27/tCO2 per year to reflect the increasing marginal cost of emissions.
