摘要
通过对攀钢焦化厂精苯再生酸的物性和组成的详细分析及现有净化方法的对比研究，提出了一种操作简便、工艺过程简单的新的再生酸净化方法──外掺沉降吸附法，并对外掺剂及吸附剂的反应条件、用量、再生等进行了详细研究。结果表明，该方法不仅能回收较纯净的可用于一般工业生产的硫酸，同时可获得较好的经济和环境效益。
Based on the detailed analyses of the characteristics and composition of refined benzene reclaimed acid produced in Pangang coke plant, and based on the comparative study of present purification methods, a new purification method, sedimentation and absorption method, is proposed. The new method is easy to operate and its technical process is simple. Also, the reaction condition, dosage and reclamation of the mixed precipitant and absorbent are studied in detail. Experimental results show that pure sulfuric acid used in common industrial productions can be reclaimed with this method, and good economic and environmental benefits can be achieved.
