精苯废酸的净化与利用

Purification of the Waste Acid from Refining of Benzene and the Utilization Thereof

以粗酚为萃取剂,试验研究了精苯再生酸的净化和利用。文中介绍了萃取剂的选择、萃取比的确定、萃取剂的再生、活性炭脱色、再生等试验情况,并给出了废酸净化的工艺流程及净废酸的利用途径。

The research work is made via experiment on the purification of the regenerated acid from the refining of benzene and the utilization thereof. In this paper there is described the selection of extractants, the determination on the extract ratio,the regeneration of the extractant, the discolouring and regeneration of active carbon and others for the experiment, giving out the technological process for purification of the waste acid and the approach for utilization of the purified waste acid.
