Determination of Suitable Concentrations of H2O and CO2 in the Feed of Syngas Production (RESEARCH NOTE)

Modeling and optimization of synthesis gas production via the non-catalytic partial oxidation of methane (NCPO) were studied by minimizing of Gibbs free energy, and comparison studies were carried out to analyze the mechanism of syngas production. For this purpose, concentrations of CO2 and H2O in the feed were optimized in specified pressure and temperature, such that the hydrogen to carbon monoxide ratio in the product was set between 1.98 and 2.02 (suitable ratio for FT and methanol synthesis process) and concentration of CH4 in the product was less than 1.5%. The predictions obtained by this simulator were in agreement with the experimental data as well as the AspenPlus® package results.
