modelWaterGasShiftReactor_L1
Extends from Base.PartialFixedBedReactorRealGas_L1 (Partial model for L1 reactor models using real gases).
Information
1. Purpose of model
This model represents a simple adiabatic water gas shift reactor with no volume in which CO reacts with steam to CO2 and H2.
2. Level of detail, physical effects considered, and physical insight
The CO conversion rate, i.e. the share of the CO that reacts, is given by a constant parameter.
3. Limits of validity
The model is only valid if the share of CO, that reacts, is not constant.
4. Interfaces
gasPortIn: real gas inlet
gasPortOut: real gas outlet
5. Nomenclature
(no elements)
6. Governing Equations
Stationary mass and energy balances considering the heat of reactions are used. The outlet composition is calculated depending on the incoming composition and the CO conversion rate.
7. Remarks for Usage
The model only works in design flow direction and it has to be ensured manually that enough steam is in the incoming stream.
8. Validation
