Atmospheric distillation unit and vacuum distillation unit Process introduction First heat up the crude oil to 90-130 ℃ through heat exchanger then add purified water and demulsifier, after mixing and then send in to electrical desalting and dewatering device to have the tiny droplets gradually extended to larger ,and then form a water layer to have water, dissolved salt, impurity ect removed. After desalting treatment, crude oil is heated up to 220-250℃ to enter in to pre-fractionator, light gasoline is extracted from top of pre-fractionator, topped crude from tower bottom through heat exchanger and atmospheric furnace to be heated up to 360-370 ℃, then enters in to atmospheric distillation tower, to separate out gasoline, kerosene ,light diesel, heavy diesel fractions, after electrochemical treatment, they’re product oil for supply. Atmospheric bottom heavy oil will be heated up to 380-400 ℃ and then flow in to vacuum distillation tower, to separate out different vacuum fractions, these fractions will be used as raw materials for catalytic treatment or lubricating oil. Vacuum residue after heat exchanged and cooled to be fuel or heat exchanged to make raw materials for coking, catalytic cracking, oxidation asphalt. Main products from atmospheric distillation unit 1. Fraction from initial boiling point to <200℃ as gasoline fraction( reforming raw material or naphtha ). 2. Fraction around 200℃ is kerosene( molecular sieve or solvent naphtha) 3. Light diesel fuel oil Fraction around 280℃ is light diesel fuel. 4. Heavy diesel fuel oil Fraction around 340℃ is heavy diesel. 5. Residuum Fraction around 360℃ is vacuum residuum Products from vacuum distillation unit 1. Light vacuum gas oil(vacuum cut 1) as raw material for heavy diesel, ethylene cracking. 2. Medium vacuum gas oil( vacuum cut 2,3) as raw material for lube oil or paraffins. 3. Heavy vacuum gas oil( vacuum cut 4) 4. Vacuum tower bottom oil is vacuum residuum as raw material for fuel oil. |
