Equivalent atomic H/C ratio of fuel for in-situ combustion
Input(s)
m: Mole Ratio of Carbon Monoxide to Carbon Emissions (fraction)
\(c_{N_{2}}\): Concentration of Nitrogen (mole fraction)
\(c_{\mathrm{O}_{2}}\): Concentration of Oxygen (mole fraction)
\(c_{\mathrm{CO}_{2}}\): Concentration of Carbon Dioxide (mole fraction)
Output(s)
x: Equivalent Atomic H/C Ratio of Fuel for in-situ Combustion (ratio)
Formula(s)
\[
\mathrm{x}=4 *(1-\mathrm{m}) *\left(\frac{0.27 * \mathrm{c}_{\mathrm{N}_{2}}-\mathrm{c}_{\mathrm{O}_{2}}}{\mathrm{c}_{\mathrm{CO}_{2}}}\right)+2 * \mathrm{~m}-4
\]
