石蜡基和中间基减压渣油生产光亮油和微晶蜡

Production of bright oil and microcrystalline wax with paraffinic and intermediate vacuum residue

以石蜡基和中间基混合原油的减压渣油为原料,利用丙烷脱沥青装置制得的轻脱沥青油,经糠醛抽提、酮苯脱蜡和补充精制工艺,可生产光亮油和微晶蜡。结果表明:轻脱沥青油的运动黏度(100℃)应不低于24 mm^(2)/s,色度不高于6.5号,残炭质量分数不高于1.5%;生产的光亮油牌号为HVI 150 BS,除色度外的其他性能均可满足Q/PBR 0008—2021要求;生产的微晶蜡牌号为80 B#,其主要性能可达到SH/T 0013—2019要求。

Light deasphalting oil was prepared by propane deasphalting unit with the residual oil of paraffin-based and intermediate blended crude oil as raw material.By furfural extraction,ketone benzene dewaxing and supplementary refining process,bright oil and microcrystalline wax were produced.The results showed that the motion viscosity(100℃)of the light deasphalt oil should not be less than 24 mm^(2)/s,the chroma should not be higher than 6.5,and the mass fraction of carbon residue should not be higher than 1.5%.The brand of the produced bright oil was HVI 150 BS,and its performance could meet the requirements of Q/PBR 0008—2021 except for chroma.The brand of the produced microcrystalline wax was 80 B#,and its main performance could meet the requirements of SH/T 0013—2019.
