褐煤加压气化污氨水的净化及回收
|
摘要
本文提出一种处理含CO_2、酚、吡啶、苯胺等杂质的污氨水的工艺流程,采用气相吸附净化,酸吸收的方法,实现了污氨水中氨的回收利用。优选出活性炭ZX—15做为吸附剂,并进行了污氨水馏出气体的吸附研究。对吸附剂进行再生,提出了贫氧氧化再生和饱和中压蒸汽再生两种流程,实现了饱和活性炭在吸附塔内的再生,降低了活性炭的装填费用,简化了操作步骤,在实际工艺生产中有积极的意义。最后结合解化集团原有的工业设备及试验结果,进行了工艺可行性分析,确定了污氨水中的氨的净化回收工艺方案。该方案可在今后的污氨水回收氨项目中推广使用。
A process flow was put forward in this article to deal with waste aqueous ammonia containing impurities such as CO_2, phenol, pyridine and phenylamine, by means of gas phase adsorption and acid absorption in order to recover ammonia in the waste solution. The active carbon ZX-15 was chosen optimally as adsorbent for this process and the study of the adsorption to the gas distilled from waste ammonia water is carried out. For adsorbent reactivation, two processes ware raised in this paper, including oxygen-poor oxidation and medium pressure saturated steam regeneration. Both of the processes can be used for the regeneration of adsorbent in the adsorber to reduce the loading cost of adsorbent and simplify the operating procedure, which is meaningful to the current production process. Besides, based on the test results and the existing unit in the Jiehua Group, the feasibility study of the process was made and the ammonia-recovering process from waste ammonia water is confirmed in this paper.The process can be widely put into operation of recoverying ammonia water project.
