Abstract

A simulation study to predict and optimize a natural gas steam reforming plant in Suez was performed. The developed model was used to generate performance data that would map the relation between atthe operating variables and hydrogen productivity. A single objective optimization problem was then formulated to maximize hydrogen production in the subunits: hydrocarbon prereformer, steam methane reformer, and the medium-temperature water-gas-shift reactor. The process temperature and pressure for the three subunits, total plant flow rate and total superheated steam flow rate were selected as decision variables. A good agreement was found between simulation results and plant data at steady-state conditions in terms of hydrogen yield and chemical composition. The developed mathematical model for hydrogen productivity correctly predicts the effect of relevant process parameters.
