.TransiEnt.Components.Gas.Reactor.Prereformer_L1

Information

1. Purpose of model

This model represents a simple adiabatic prereformer with no volume which decomposes the hydrocarbons C2H6, C3H8 and C4H10 with steam into CH4 and CO.

2. Level of detail, physical effects considered, and physical insight

The higher hydrocarbons are decomposed completely, there are no reaction rates or equilibrium reactions. A constant pressure loss is assumed.

3. Limits of validity

The model is only valid if the remaining hydrocarbons are negligible.

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.

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

Tested in the check model "TransiEnt.Components.Gas.Reactor.Check.TestPrereformer_L1"
