Refinery fuel gas

Non-condensable refinery gas of crude distillation and conversion units: hydrogen, methane, ethane, some C3, and ethylene from cracking units, with H2S before amine treating; burnt in the refinery's heaters (refinery-distillation-1 overhead gas, fcc-1 dry gas, hydrocracking-1 C1-C2 gas). Composition by unit and site. No composition recorded yet: one goes in only with its source (docs/registry.md, Fuel mixtures).

Routes compared

All 4 ways to make Refinery fuel gas, with filters →

Not comparable as they standSystem boundary: differs; Data quality (TfS DQR): not stated by every route; Reference product (grade, state): not stated by every route. The rows say which route each warning concerns.

Per 1 kg of Refinery fuel gas: inventory from each route's LCI dataset, unallocated; footprints per the functional unit of their own LCA.

Functional unit: same (same functional unit (amount and unit of the reference product): 1 kg)
Reference product (grade, state): not stated by every route (same reference product: registry grade and state)

ISO 14044 requires a critical review (by a panel of interested parties, ISO/TS 14071) of a comparative assertion intended to be disclosed to the public. These routes are listed side by side for screening; a statement that one is better than another needs that review. None of these routes has had such a review.
