Unit Description

Consists of processing & support fasilities designed for the production of lubricatingoil base stoke & food grade wax.

The process units which are included in the plant are listed as follows:

  •   Vacuum distillation unit
  •   Propane deasphalting unit
  •   Furfural extraction unit
  •   MEK dewaxing and wax fractionation unit
  •   Lube oil hydrofinishing unit
  •   Wax hydrotreating unit


The general processing scheme for the plant is out lined in black flow diagram.


V

Unit 1000 acuum distillation unit .

The function of the vacuumdistillation unit is to separate long reduced crude into vacuum gas oil, spindle oil, three side stream waxy distillation, a black oil cut and a short residue which is the main product to produce the lube oil.
P

Unit 2000 ropane deasphalting unit.

The function of the propane-deasphalting unit is to remove the asphalt and resins from the short residue from the bottom of vacuum tower by propane solvent producing deasphalted oil. This unit improve the color of lube oil.
F

Unit 3000 urfural extraction unit.

The function of this unit is to refine propane deasphalted oil to remove aromatic materials by furfural solvent. The raffinates produced from the unit shall be suitable for producing finished base stock after further processing in this unit viscosity index (V.I) will be increased.
M

Unit 4000 EK dewaxing and wax fractionation unit.

The function of this unit is to separated the Raffinate from Furfural unit in to wax and oil by Methyl. Ethyl Ketone and Toluene solvents-pour point and viscosity of oil will be improved.
L

Unit 5000 ube oil hydrofinishing unit.

The function of this unit shall be to process in " blocked operation " all of the dewaxed oil from the MEK dewaxing unit to Obtain satisfactory color, oxidation stability. The unit shall be designed to operate in series with the MEK unit without intermediate tankage between the units.
W

Unit 6000 ax hydrotreating unit.

The function of this unit shall be to process in " blocked operation " all of the hard waxes from the MEK unit to Obtain satisfactory color, oxidation stability and other essential characteristics for food grade waxes.
