摘要
对加拿大油砂稀释原油进行了常减压蒸馏-溶剂(正戊烷)脱沥青-调和改质加工工艺优化研究.结果表明:萃取温度180℃、剂油比(溶剂与减压渣油的体积比)8∶1、萃取压力4.4 MPa为较优的脱沥青萃取工艺条件;在上述较优条件下制备的脱沥青油与常、减压馏分油按比例调和,并掺加体积分数为16.5％的稀释剂(石脑油)所制得的合成油,不仅满足加拿大管输油的标准要求,还降低稀释剂掺量的45％～52％;而且,所得脱油沥青能够有效改善基质沥青的高温性能,可作为性能优异的硬质沥青改质添加组分.
Abstract
The optimization of the atmospheric and vacuum distillation-solvent(n-pentane)deasphalt-ing-blending modification process was carried out on the diluted crude oil from Canadian oil sands.The results showed that the optimal extraction conditions were extraction temperature at 180 ℃,solvent to oil ratio(volume ratio of solvent to vacuum residue)at 8:1 and extraction pressure at 4.4 MPa.The syn-thetic oil was prepared by blending the deasphalted oil produced under above optimal conditions with the atmospheric and vacuum fractions in proportion,and adding the diluent(naphtha)with the volume frac-tion of 16.5％,which could not only meet the re-quirements of Canadian pipeline oil transportation standards,but also reduced the diluent dosage by 45％-52％.Moreover,the obtained deoiled asphalt could effectively improve the high-temperature per-formance of the base asphalt,and be used as an ad-ditive component to upgrade hard asphalt with ex-cellent performance.
