UN-CONVERSED OIL FROM HYDROGENATION PROCESS OF FUEL OIL AND METHOD FOR REMOVAL OF NITROGEN COMPOUND FROM FRACTIONS BY VACUUM DISTILLATION OF THE UN-CONVERSED OIL |
摘要 |
PURPOSE: Provided are an un-conversed oil from hydrogenation process of fuel oil and a method for removal of nitrogen compound from fractions by vacuum distillation of the un-conversed oil and to produce high quality and heavy lubricant base oil source. CONSTITUTION: The process comprises a first vacuum distillation step(R1); a first hydrogenation step(R2); a series of fractional distillation step(Fs); a second vacuum distillation step(V2); and a nitrogen removal step(P1). The first step(R1) is for removing asphalt from residual oil. The first hydrogenation step(R2) is to remove impurities from the de-asphalt oil from the first step(R1). The fractional distillation step(Fs) separates oil products and the un-conversed oil. The second vacuum distillation step(V2) is to produce high quality and heavy lubricant base oil source and the un-conversed oil residual. The last step(P1) is for removing nitrogen compounds by adsorption out of the lubricant base oil source.
