Claus process - Wikiped

The Claus process is the most significant gas desulfurizing process, which requires the use of a special burner in the reaction furnace for this process option. (hot gas) from the first pass of the waste-heat boiler. Indirect steam reheaters: the gas can also be heated with high-pressure steam in …

Multi-scale modeling of Claus thermal furnace and was

File Size: 538KB This work introduces the multi-scale modeling approach to characterize the kinetic and reaction engineering scales for the thermal section of SRUs, involving the reactor furnace and the waste heat boiler. Specifically, also the waste heat boiler is modeled using detailed kinetics to characterize the recombination effects, which cannot be

Multi-scale modeling of Claus thermal furnace and was

Thermal reaction furnace and waste heat boiler can be simulated by means of several kinds of reactors in series. This simplified configuration (computational fluid-dynamics is not considered) is also useful for on-line purposes since it allows to perform simulations with small computational effort.
