Reduced order modeling of the Shell-Prenflo entrained flow gasifier

► ROM of the Shell gasifier enables the integration of gasifier and overall IGCC simulation. ► Detailed model of the reactor, the membrane wall and the gas quench is developed. ► Calculated cold gas efficiency is 82.5%, outlet temperature is 1588 °C. ► Carbon conversion is sensitive towards O/coal ratio. ► CGE increases to 83.5% when coal is charged with CO2 instead of N2.
