Irreversible reaction

Neutralisation of the brine alkalinity by the acid (R-101)

Direction: Irreversible
Processes: 1
Stated as: Fixed conversion
Heat of reaction: ΔH = 25,300 kJ/kmol (one process)
Element balance: Checked: balances

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.

Conversion
100 % of NaHCO3 (assumed: D-004: the brine is acidified to pH about 2.4, far below the bicarbonate's pKa)
Heat of reaction
ΔH = 25,300 kJ/kmol at 298.15 K, as written (assumed: HCO3-(aq) -692.0, CO2(g) -393.5, H2O(l) -285.8 kJ/mol (NBS tables, D-007))
