中文摘要 | 為符合環保法規之要求與成本之降低,煉焦爐氣脫硫系統之設計與操作有必要尋求最佳化。本文針對硫化氫洗滌塔建立一個嚴謹的速率模式。此模式除考量了熱質傳外,並納入了涉及硫化氫、氨與二氧化碳之複雜的可逆化學反應。此模式毋需使用建立於簡化的反應機制假設條件之上的加強因子。此模式可被擴展應用於氨洗滌塔、去酸塔與氨蒸餾塔等煉焦爐氣脫硫系統之主要設備的模擬。 此模式建立了液膜內各成分之濃度曲線圖與溫度曲線圖。對一個典型的硫化氫洗滌塔,硬化氫、氨與二氧化碳之吸收效率模擬結果分別為86.4%、60.2%與4.0%。 |
英文摘要 | Due to the need to meet stringent environmental regulations and to minimize capital and operating costs, the design and operation of coke-oven-gas (COG) desulfurization processes must be optimized. For □S scrubbers, this paper presents a rigorous rate model that accounts for not only mass and heat transfer mechanisms, but also complex and reversible chemical reactions involving □S, C□, N□ and associated ions. The model need not use a chemical enhancement factor based on simplified reaction mechanisms. This model can be extended to simulation of N□ scrubbers, deacifiers and N□ stills of COG desulfurization processes. The model established liquid-film concentration profiles of individual components and temperature profile. For a typical industrial □S scrubber, the predicated absorption efficiency for □S, C□ and N□ is 86.4%, 4.0% and 60.2%, respectively. |
