خلاصه مقاله:
For the first time, computational fluid dynamics technique is applied to dynamically simulate catalytic reforming rectors on industrial scale. Transport phenomena for momentum, heat, massand turbulence are simultaneously solved through the domain of fluid. Additionally, heat transferequation is solved for solid-state regions. Twenty-four irreversible reactions involving fourpseudo-components in the feedstock, namely aromatics, naphthenes, paraffins and coke, areconsidered to occur into the catalytic beds. All reactions are treated as Arrhenius type when acting as stiff class of ordinary differential equation in their solution procedure. Coke formation is taken into account for the first time with two pressure-ependent reactions. The kinetic scheme isobtained from numerous experiments established on the pilot plant and its parameters are adjusted to the plant data. Results show good agreement between simulation and plant data so thatmaximum relative error reached for research octane number is less than 2 per cent.
