摘要
论述了辽化的精对苯二甲酸装置 (PTA)的废渣回收利用方法。无机物废渣经过处理回收了硫化钴。含苯甲酸 42 %～43 %的有机物废渣 ,用升华方法回收到纯度为 99 7%的食品添加剂级苯甲酸。由废钯催化剂用吸附法可回收得到纯度达99 95
The recovery utilizing method of waste residue in PTA plant of Liaoyang Petrochemical Company was discussed.CoS was recovered from the inorganic waste residue.Pure food additive grade benzoic acid(purity 99.7 %)was obtained by the sublimation method from the waste residue which contained 42%～43%,benzoic acid.Pure Pd(purity 99.95%)was recovered from the waste Pd C catalyst by absorption method.
