Method in order to produce basic oil blend from wax condition raw materials with the distillation which extracts the plural side streams

摘要

Initial boiling point below approximately 340 , terminus is produced from wax condition raw materials above approximately 560 , below producing the product slate which at least includes the basic oil grade of 3 where kinematic viscosity with the 100 approximately is inside the range 1.8 - 30cSt types the process which includes process:(A) the same wax condition raw materials at least isomerizing processing part, the process which rises the density of that isoparahuin,(B) the first part of the wax condition raw materials which it was isomerized were processed the process which at least produces the basic oil fraction of 3 where it possesses the boiling point range which differs in the distillation with the block operational mode of light amount types,(The second part of the wax condition raw materials which c) it was isomerized were processed the process which at least produces the basic oil fraction of 3 where it possesses the boiling point range which differs in the distillation with the block operational mode of average quality amount types, andBlending the basic oil fraction of 1 where it is produced at least by the basic oil fraction of 1 where it is produced (d) by the block operational mode of light amount types and the block operational mode of average quality amount types at least, the process which produces the lubricant basic oil blend which makes the set point of the characteristics satisfy where 1 types are beforehand selected at least.
