临商原油利用蒸馏—溶剂脱沥青过程生产道路沥青

PRODUCING ROAD ASPHALT FROM LIN-SHANG CRUDE OIL USING DISTILLATION AND SOLVENT DEASPHALTING PROCESSES

临商原油本属于不适合于生产沥青的原油（Ａ＋Ｒ－２．５Ｐ≤－１５），在石蜡含量高的临南原油混入其中后，使得道路沥青的生产更加困难；采取了提高减压拔出深度、改变渣油组成、改变溶剂脱沥青操作参数等措施，使道路沥青质量得到改善。

Lin-Shang crude oil is not suitable for producing asphalt because of its A+R-25 P-15It is more difficult to produce asphalt when mixing Lin-Nan crude oil with higher wax contentMeasures such as increasing yield of distillates,varying components of residue and operation parameters of solvent deasphalting unit were taked,So quality of asphalt improved
