废氨汽用于烧结烟气脱硫或生产硫酸铵

Utilization of waste ammonia vapor for emission desulfurization in sinter plant or ammonium sulfate production

将AS流程中原来焚烧掉的氨汽回收后,用于氨法烟气脱硫,每年可减少液氨采购量4500t,直接经济效益达1710万元。将浓氨水送到饱和器生产硫酸铵化肥,每年可生产硫酸铵18250t,经济效益达2555万元。

Ammonia recovery process is described in this paper, i.e. the ammonia vapor used to be burnt out in A.S. process will be recovered for emission desulfurization in sinter plant, with liquefied ammonia saved by 4 500t annually and with direct economic benefit up to 17.1 million RMB; the concentrated ammonia liquor is delivered to saturator for producing ammonia sulfate fertilizer, with production of 18 250t each year and with economic benefit up to 25.55 million RMB.
