Disclosed is a method of manufacturing high quality lube base oil (Group III) from unconverted oil having various properties obtained in a variety of hydrocrackers using improved catalytic dewaxing and hydrofinishing, the method including producing unconverted oil of at least one kind in the same or different hydrocrackers; subjecting the unconverted oil to vacuum distillation; supplying all or part of the distillate fractions to a catalytic dewaxing reactor; supplying the dewaxed oil fraction to a hydrofinishing reactor; and stripping the hydrofinished light oil fraction, wherein make-up hydrogen is supplied upstream of the hydrofinishing reactor to increase hydrogen partial pressure, thereby enabling high quality base oil to be manufactured at high yield under optimal process conditions using unconverted oil produced by hydrocracking under various conditions.

Method of manufacturing high quality lube base oil using unconverted oil

A quenching apparatus for a reactor is disclosed. The quenching apparatus includes a quenching unit () and a mixing unit (). The quenching unit includes fluid distribution pipes () which branch off from a central portion of the quenching unit in radial directions and eject quenching fluid, and one or more first fluid outlets () which are formed through the bottom of the quenching unit. The mixing unit includes inclined baffles (), one or more partitions () and a second fluid outlet (). The inclined baffles are respectively disposed under the first fluid outlets. The partitions partition a space between inner and outer sidewalls of the mixing unit into a plurality of separated spaces in which the inclined baffles are respectively disposed. Fluid guided by the inclined baffles and the partitions is discharged out of the mixing unit through the second fluid outlet.
