摘要
为提高硫回收率 ,减轻对环境的污染 ,采用富氧技术对 6kt/a常规克劳斯法硫回收装置进行了改进。在研究了富氧空气引入方式、装置负荷、氧化配风和富氧空气集输等技术后 ,经工艺核算 ,制定了利用现有 10 0 0m3 /h、含氧量为 33.5 %的富氧资源并采用相关安全防范措施的改造方案。装置改造后的标定结果表明 ,氧化风的氧含量由 2 1%提高到 2 8% ,酸性气处理能力提高了2 8.3% ,硫磺产量提高了 2 9.6 %。
A 6kt/a conventional Claus sulfur recovery unit was revamped with the technology using oxygen-enriched air for increasing the sulfur recovery rate and reducing environment pollution. Process calculation was taken after studying the introducing way of the oxygen-enriched air, unit capacity, oxidation air dispatching and the oxygen-enriched air transporting. A revamping scheme, using the existed oxygen-enriched air resource having oxygen content of 33.5% together with safety measures, was formulated. The test run calculation showed that the acid gas treating capacity increased by 28.3% and the sulfur production increased by 29.6% after the oxygen content of air raised from 21% to 28%.
