综合治理合成氨装置硫化氢恶臭

Compreheusive Treatment of the H2S Odor for the Ammonia Synthetic Unit

镇海炼化股份公司化肥厂合成氨装置，通过挖潜改造，工艺上进行优化操作，提高了流化氢废气处理量，使硫磺装置开工率和回收率分别达到99．7％和99．0％；使合成氨装置H：S废气全部回收，消除了装置区H2S恶臭，年增产硫磺2503t，取得了明显的环境效益和经济效益．

The capacity of H2S treatment was enhanced,and utilization of capacity and rate of H2S recovery reach to 99. 7% and 99. 09% separately,by the process operation optimization and improvement in the the sulfur unit of the ammonia synthetic plant. The H2S was recovered completely,the H2S odor was removed and production of sulfur 2530t/a was increased. The obvious environmental and economic benefit were obtained.
