Basis and limits
Equal co-removal of CO₂ and H₂S sets the base acid gas. The sales gas CO₂ specification bounds selective treating. The oxidizer is adiabatic, water-saturated acid gas at 25 °C, methane support fuel, no heat recovery, NIST Shomate enthalpies. SO₂ is reported dry at 25 °C, 1 atm and 0% O₂. Injection compresses from 1.6 to 80 bara in four stages and pumps to the set pressure, with a 33% gas-fired driver. Recovery routes vent the acid gas CO₂ and exclude utilities. Alkaline routes carry R/S, the CO₂ absorbed per mole of H₂S, with the selectivity S defined on absorbed fractions. Above 1 they are flagged conditional. The pH ceiling uses about 1.45 atm CO₂ and 0.18 to 0.71 M alkalinity. Carbon intensity divides the CO₂ emitted at the facility by the energy in the sales gas; the buyer's combustion adds about 53 kg per MMBTU (US EPA factor). Capital cost is out of scope.
This is a concept-select screen on public data. A carried route still needs vendor data, a permit check and, for injection, a subsurface assessment.
