Feasibility study for the production of narrow, closely fractionated lube oil cuts

Production of narrow-distillation oil distillates

“…

665.637.046.5 Modern technology for production of the entire spectrum of narrow-distillation oil distillates for manufacture of base oils using the latest contact devices and a new system for creating the vacuum in the vacuum tower is examined.Narrow-distillation distillates are necessary for manufacturing high-quality lube oils from petroleum feedstock [1,2]. High-efficiency contact devices with low resistance to movement of the vapor stream and low residual pressure, a maximum of 6.5 kPa, in the atmospheric resid fractionation system ensure such distillates.
