摘　　要：目的去除炼油厂酸渣中含有的大量硫酸,使其有价值的有机物部分被有效利用.方法选用氨水-乙醇-水的复合除酸剂对酸渣进行处理.检测沥青防水卷材的一些力学性能确定渣油的掺入量.结果除酸剂组分为w(氨水)=30%,w(乙醇)=8%,w(水)=62%,搅拌速率为250～300r.min-1,反应温度为55℃,反应时间为20min,沉降时间为30min,剂油体积比为0.4的条件下可有效地去除硫酸,渣油的酸值降为10mg/g.结论处理后的渣油可替代30%的沥青用于生产自黏性改性沥青防水卷材,产品质量完全满足指标要求.The paper aimes to provide methods to wipe off plenty of sulfuric acid of the acid sludge formed from oil refinery and the most valuable part of the organic matter in acid sludge can be used efficiently.Dealing acid sludge with ammonia-ethanol-water,the mechanical performance of asphalt waterproofing coiled material is tested to confirm the amount of residue.The results show that components of acid-removing agent are w（ammonia）=30%,w（ethanol）=8%,w（water）=62%,under the conditions of the stirring speed for 250 r/min^300 r/min,reaction temperature for 55 ℃,reaction time for 20min,the settling time for 30min,the ratio of solvent to oil for 0.4,the sulfuric acid can be removed effectively and the petroleum residue of acid sludge can be lowered down to 10 mg/g.The recovered oil can replace 30% of asphalt and be used in the production of self-adhered modified asphalt waterproofing membrane,the quality of the product completely satisias the index.
