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.

Starter template

A starting template is in the ChemE-as-Code toolkit (Methyl tert-butyl ether): cheme chemistry library mtbe --add

Templates bring the stoichiometry, the components and typical catalysts; most give no conversion or kinetics, and their sources are general references, not this reaction's processes.
