dc.description.abstract | At high temperatures found in the modified Claus reaction furnace, the thermal decomposition of H2S yields large quantities of desirable products, gaseous hydrogen (H2) and sulphur (S2). However, the reverse reaction occurs at the much lower operating temperatures found in the waste heat boiler (WHB) which is located downstream of the furnace. To examine the reaction quenching capabilities of the WHB, a rigorous computer model was developed for the boiler incorporating recently published intrinsic kinetic data. A sensitivity study performed with the computer model demonstrated that WHB's are conservatively designed. Most important, the computer model showed that it was possible to operate a WHB such that quench times could be reduced by over 60% down to less than 40 ms compared to a base case scenario. Furthermore, H2 production could be increased by over a 20% simply by reconfiguring the boiler tubes. | |
