Good morning,

My question is concerning modeling of chemical reactions.

I would like to know if it is possible to create a flow of a substance as an export flow wich depends to the value of an import flow without having the new substance in the import flow ?

As an example for just a bloc of process : Masse flow susbtance B (flow2) = 2 x masse flow substance a(flow1).
Because I tried to create relation between those flows and STAN doesn't accept to have 0 t/year of the substance b in the import flow.


Thank you in advance for your help,

A. LE FLOCH

Unfortunately, STAN cannot model stochiometry. On each substance layer, the mass flows must comply with the law of mass conservation, i.e. the mass balance of each process must be fulfilled. So, it is not possible for substances to be created or destroyed/transformed.
