Simtronics’ SPM-7010 Hydrogen Plant produces hydrogen in a series of reactors:
- hydrodesulfurizer to remove sulfur from light hydrocarbon feedgas.
- pre-reformer to partially steam reform feedgas and feed steam to a mixture primarily containing H2, CO, CO2, H2O and CH4.
- fired steam reformer to provide additional conversion of CH4 to H2, CO and CO2 and to provide the heat input for the reactions.
- medium temperature shift (MTS) converter to convert most of the CO to CO2 and produce additional H2.
After the reaction section, the process gas is cooled and fed to a PSA unit to remove the residual concentrations of CO, CO2 and H2O in the process gas to produce a highly pure hydrogen product. Then the CO2 is liquified and sent to underground storage.
