Oil Refinery and Petrochemical
Jereh refinery and petrochemical business unit, an integrated solution provider, is working together with strategic partners to provide EPC, maintenance and operation service for refinery and pipeline as well as gas station in the flexible project modes of EPC+F, BOT and BOOT. The major process units are: Atmospheric and Vacuum Distillation Unit, Fluid Catalytic Cracking Unit, Delayed Coker Unit, Hydrocracking Unit, Naphtha/Diesel/Jet Fuel Hydrotreating Unit, Catalytic Reforming Unit, Sulfur Recovery Unit, Hydrogen Generation Unit, Alkylation Unit, MTBE Unit, etc.

Typical Processing Units

  • 01
    Atmospheric Distillation Unit
    Major process sections: preheat trains, vacuum towers and heaters, and vacuum ejectors.
    The objective of vacuum distillation is to recover a large volume of gas oil at near vacuum conditions.
    Major process sections: desalters, preheat trains, atmospheric towers and heaters.
    The objective of atmospheric distillation is to fractionate crude oil into light-end hydrocarbon (C1-C4), naphtha, Kerosene, diesel, and atmospheric residue at closed to atmospheric pressure.
  • 02
    Fluid Catalytic Cracking Unit(FCCU)
    Major process sections: reactor-regeneration, fractionator, FCC gas concentration, air blowers, rich gas compressors etc.
    Fluid catalytic cracking is an efficient refinery process for conversion of heavy gas oils into preliminary components of gasoline and diesel.
  • 03
    Delayed Coker Unit
    Major process sections: coker furnace, coker drums, fractionator, coker gas concentration etc.
    Delayed coking is a thermal process which the vacuum residue from vacuum distillation is heated in a furnace, then confined in a coke drum under proper operating conditions to produce coker naphtha, coker kerosene, coker diesel, coker gas oil and coker.
  • 04
    Hydrocracking Unit
    Major process sections: reactor and distillation.
    Distillate hydrocracking is a refining process for conversion of heavy gas oils or similar boiling-range heavy distillates into light distillates. (naphtha, kerosene, diesel, etc.)
  • 05
    Hydrotreating Unit
    Major process sections: feed heater, rector and distillation etc.
    Hydrotreating processes aim at the removal of impurities such as sulfur and nitrogen from distillate fuels of naphtha, kerosene and diesel by treating the feed with hydrogen at elevated temperature and pressure in the presence of a catalyst.
  • 06
    Hydrogen Generation Unit
    Major process sections: natural gas desulfurization, steam reforming, high and low temperature shift conversion and trace CO and CO₂ removal etc.
    Most refinery hydrogen is produced by the steam reforming of natural gas.
  • 07
    Catalytic Reforming Unit
    Major process sections: feed heaters, reactors and debutanizers etc.
    The aim of catalytic reforming is to transform, as much as possible, hydrocarbons with low octane to hydrocarbons with high octane. The chemical reactions that lead to these changes are guided by a catalyst under well-defined operation conditions.
  • 08
    MTBE Unit
    Major process sections: reactors, catalytic column and methanol recovery column etc.
    Methyl tertiary butyl ether (MTBE) is produced by the reaction of isobutene with methanol. Its main use is as a gasoline blending component, due to its high octane level.(RON=115—135, MON=98--100)
  • 09
    Sulfur Recovery Unit
    Major process sections: main burners, converters, and condensers and sulfur sumps, etc.
    Sulfur recovery process recovers hydrogen sulfide from various refinery gaseous streams by scrubbing with an amine solution and convert it to element sulfur by controlled oxidation.
