SeriesReaction

class thermosteam.reaction.SeriesReaction(reactions)

Create a ParallelReaction object from Reaction objects. When called, it returns the change in material due to all reactions in series.

Parameters

reactions (Iterable[Reaction]) –

force_reaction(material)

React material ignoring feasibility checks.

adiabatic_reaction(stream)

React stream material adiabatically, accounting for the change in enthalpy due to the heat of reaction.

Examples

Note how the stream temperature changed after the reaction due to the heat of reaction:

>>> import thermosteam as tmo
>>> chemicals = tmo.Chemicals(['CH4', 'CO','O2', 'CO2', 'H2O'], cache=True)
>>> tmo.settings.set_thermo(chemicals)
>>> reaction = tmo.SeriesReaction([
...     #            Reaction definition                 Reactant       Conversion
...     tmo.Reaction('2CH4 + 3O2 -> 2CO + 4H2O',       reactant='CH4',    X=0.7),
...     tmo.Reaction('2CO + O2 -> 2CO2',               reactant='CO',     X=0.1)
...     ])
>>> s1 = tmo.Stream('s1', CH4=5, O2=100, H2O=100, T=373.15, phase='g')
>>> s1.show() # Before reaction
Stream: s1
 phase: 'g', T: 373.15 K, P: 101325 Pa

                 O2   100
                 H2O  100

>>> reaction.show()
