As the processes state itStoichiometry, conversions, heats of reaction and catalyst windows are taken from each process's files with their provenance. The build checks only that each process's equation balances in every element, from the process's own component formulas; it does not check the numbers. A process's design maturity applies to them.

    Balances in every element
    Conversion
    95.5 % of NaBr (assumed: D-005: 95-96 % bromine recovery of conventional steaming-out towers (US 4 719 096, Detailed Description); midpoint; equals the recovery to product because no other bromine loss is modelled)
    Heat of reaction
    ΔH = -93,810 kJ/kmol at 298.15 K, as written (assumed: 2 Br-(aq) + Cl2(g) -> 2 Cl-(aq) + Br2(aq) from NBS tables (Wagman et al. 1982) formation enthalpies, recalled, to verify (O-5))
