The modeling of thermal reaction furnaces of Sulfur Recovery Units (SRUs) is a rather complex problemsince it involves different modeling scales such as the kinetic/molecular scale, the reactor scale, andthe chemical process scale. This work introduces the multi-scale modeling approach to characterize thekinetic and reaction engineering scales for the thermal section of SRUs, involving the reactor furnaceand the waste heat boiler. Specifically, also the waste heat boiler is modeled using detailed kineticsto characterize the recombination effects, which cannot be neglected any longer since they significantlyinfluence the outlet compositions. The proposed models are validated on experimental and literature datafor the kinetic scale. The reactor scale is validated on the industrial data coming from SRUs operating inNanjing and Mumbai plants.

Abstract
The modeling of thermal reaction furnaces of Sulfur Recovery Units (SRUs) is a rather complex problemsince it involves different modeling scales such as the kinetic/molecular scale, the reactor scale, andthe chemical process scale. This work introduces the multi-scale modeling approach to characterize thekinetic and reaction engineering scales for the thermal section of SRUs, involving the reactor furnaceand the waste heat boiler. Specifically, also the waste heat boiler is modeled using detailed kineticsto characterize the recombination effects, which cannot be neglected any longer since they significantlyinfluence the outlet compositions. The proposed models are validated on experimental and literature datafor the kinetic scale. The reactor scale is validated on the industrial data coming from SRUs operating inNanjing and Mumbai plants.File | Dimensione | Formato | |
