摘要
介绍了苯胺废水中苯胺回收的工艺流程,对国内某企业的苯胺废水中苯胺回收工艺进行了分析,提出了节能减排的改造方案。将该方案用于苯胺废水处理能力9万t/a的生产装置后,只需增加很少的设备投资,可使蒸汽消耗量降低32%,循环水消耗量降低33%,排放废水中苯胺含量降低60%,效益约增加130万元/a。
The recovery process for aniline from waster water is introduced and analyzed. An improvement measure for aniline recovery process is presented for energy-saving and discharge-reducing. The new process is applied to an enterprise with aniline production capacity of 90 kt/a, with a less equipment investment, the consumption of steam decreases by about 32%, recycle water,33% ,and the concentration of aniline in discharged water reduces by 60% ,and the modification can make the economic benefit increased by 1.30 million Yuan per year.
