在自制的中试溶剂脱沥青装置上对影响ＤＯＡ以及ＤＡＯ的收率和质量的主要因素即抽提塔顶温度和溶剂比进行了探讨，结果表明，该中试装置具有较好的溶剂抽提和分离效率。对大庆－黄岛减渣直接由溶剂脱沥青装置得到的ＤＯＡ不符合道路沥青要求，必须对其进行改质，以制得合格的道路沥青。
The main factors influencing the yield and quality of DOA and DAO, ie, the extraction temperature and the solvent ratio, were studied in a pilot-scale solvent deasphalting unit. The results showed that the pilot plant had good solvent extraction And separation efficiency. DOA obtained from Daqing-Huangdao slag reduction directly by solvent deasphalting does not meet the requirements of road asphalt and must be modified to produce qualified road asphalt.
