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)

$$ \mathrm{x}=4 *(1-\mathrm{m}) *\left(\frac{0.27 * \mathrm{c}_{\mathrm{N}_{2}}-\mathrm{c}_{\mathrm{O}_{2}}}{\mathrm{c}_{\mathrm{CO}_{2}}}\right)+2 * \mathrm{~m}-4 $$
