Net coupled sulfur/nitrogen hydrotreating operating receipt

RefineryHydrotreatingSulfurNitrogenNetOperatingReceipt composes the qualified hydrogen operating receipt and fired-heater heat-recovery credit on a common liquid-feed basis. A caller-owned carbon price is applied to the combined hydrogen-supply and net fired-heater fuel emissions.

RefineryHydrotreatingSulfurNitrogenNetOperatingReceipt net =
    RefineryHydrotreatingSulfurNitrogenNetOperatingReceipt.calculate(
        hydrogenOperatingReceipt, heatRecoveryCredit, callerCarbonPricePerTonneCo2e);

double externalEnergyMWhPerTonne = net.getTotalExternalEnergyMWhPerTonneFeed();
double emissionsKgCo2ePerTonne = net.getTotalEmissionsKgCo2EquivalentPerTonneFeed();
double operatingCostPerTonne = net.getTotalOperatingCostPerTonneFeed();

The receipt closes three auditable identities:

total external energy = fresh-H2 energy + net fired-heater fuel energy
total emissions = hydrogen-supply emissions + net fired-heater fuel emissions
total cost = H2 purchase cost + net fuel cost + combined carbon cost

For the public 1000 kg/h DOE/OEDI Big Hill chain, the qualified 60% heat-recovery scenario, 75% caller-owned recovered-heat utilization, and an illustrative carbon price of 100 currency units/t CO2e give 1.018063442 MWh/t external energy, 223.315219137 kg CO2e/t emissions, and 54.138738997 currency units/t operating cost. These values qualify composition and arithmetic only. The carbon price, fuel price, hydrogen price, emissions factors, furnace efficiency, recovery fraction, and utilization fraction remain caller-owned inputs or qualified upstream scenario inputs; none is a default or recommendation.

The receipt does not establish a lifecycle boundary, allocate shared utilities, size equipment, optimize heat integration, choose market or carbon prices, predict stack conditions, qualify corrosion or operability, or make compliance or design claims. Independent process-heat, emissions-boundary, and economic review is required for project use.
