The IDAES Stoichiometric reactor model represents a unit operation where a single material stream undergoes some chemical reaction(s) subject to a set of extent or yield specifications.
Stoichiometric reactors generally have degrees of freedom equal to the number of reactions + 1.
Typical fixed variables are:
- reaction extents or yields (1 per reaction),
- reactor heat duty (has_heat_transfer = True only).
Alternative approaches for specifying the performance of stoichiometric reactors are parameters such as conversion or selectivity. However, these parameters are defined with respect to a specific key component within the system, which is difficult to implement in a general fashion. Users are encouraged to implement additional variables and constraints to represent these parameters if desired.
The core Stoichiometric reactor unit model consists of a single ControlVolume0DBlock (named control_volume) with one Inlet Port (named inlet) and one Outlet Port (named outlet).
Stoichiometric reactors units add the following variables:
| Variable | Name | Notes |
|---|---|---|
| Xt | rate_reaction_extent | Extent of reaction, indexed by time and reactions |
| Qt | heat | Only if has_heat_transfer = True, reference to control_volume.heat |
| deltaPt | pressure change | Only if has_pressure_change = True, reference to control_volume.deltaP |
Stoichiometric reactor units write no additional Constraints beyond those written by the control_volume Block.
