Information

1. Purpose of model

This is a controller to control the steam mass flow rate for a steam methane reformer to ensure a given molar steam to methane ratio at the inlet of the prereformer.

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

The composition and mass flow rate of the feed are measured and the necessary steam mass flow rate is calculated using the amount of C atoms in hydrocarbons in the feed.

3. Limits of validity

The validity is limited because the composition is measured ideally and continuously which is not possible in reality.

4. Interfaces

m_flow_feed: input for the feed mass flow rate in [kg/s]

xi: input for the mass fractions of the feed in [kg/kg]

m_flow_steam: output for the steam mass flow rate (positive sign) in [kg/s]

5. Nomenclature

(no remarks)

6. Governing Equations

The steam mass flow rate is calculated using the amount of C atoms in hydrocarbons in the feed.
