Feasibility study for mega plant construction of synthesis gas to produce ammonia and methanol

► Best operational parameters to operate the ATR are obtained. ► When air is fed, parameters are 0.575 O2/C, 1.5 H2/CO, 600.15 K and 0.34 CO2/C. ► The H2/CO ratio is favored with high steam concentration in the feed. ► Good conversion and yield are obtained when CO2 is introduced in the feed. ► Process without natural gas oven produce 9787 MM N m3/year of synthesis gas.
