| 摘 要： | 介绍了安钢焦化厂剩余氨水处理系统的工艺流程,分析了剩余氨水焦油含量高的主要原因。采取的改进措施:在鼓冷工序增加了焦油氨水分离槽;将蒸氨工序原料槽改为除焦油槽,延长了焦油氨水的分离时间;加强了对剩余氨水槽及蒸氨原料除焦油槽的放油。通过改进,降低了剩余氨水中的焦油含量,由改进前的平均500mg/L以上降为200mg/L左右,改善了外排水质,具有较好的经济效益和社会效益。

| Abstract: | The process for treating the surplus ammonia water from the coking plant of Anyang Iron and Steel Corporation was introduced and the main cause of the high tar content in the surplus ammonia water was analyzed.After making technical breakthrough and revamping the process,and adding a tar and ammonia water separator,the time for their separation was extended.Besides,a sensible and periodical tar discharge system was established,as a result,the tar entrained in the surplus ammonia was reduced.With all those m... |
