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.

What the processes cite for this reaction, each source once: for the reaction itself, its conversion, its heat of reaction or its catalyst. As the processes write them; DOIs, US patent numbers and web addresses are linked.

  1. D-006: all coke sulfur leaves as SO2 (H2S, COS and sulfur retained in the products neglected)

    For the conversion · cited by Silicon carbide by the Acheson process (5000 kg/h crude SiC, concept)

  2. formation enthalpy of SO2(g) (NIST-JANAF, D-007)

    For the heat of reaction · cited by Silicon carbide by the Acheson process (5000 kg/h crude SiC, concept)

  3. complete combustion of the sulfur in excess air (D-004)

    For the conversion · cited by Sulfuric acid from sulfur burning, double contact / double absorption (1000 t/d, 98.5 wt%)

  4. dHf SO2(g) (CRC) with S(rhombic) at 298.15 K; molten feed adds about 5 kJ/mol (fusion and sensible), counted in scripts/balance.py

    For the heat of reaction · cited by Sulfuric acid from sulfur burning, double contact / double absorption (1000 t/d, 98.5 wt%)
