    • Asphaltic crude
      Petroleum with a high content of naphthenic compounds, such as asphaltenes. Asphaltic crude is also known as naphthene-based crude oil when the paraffin wax content is low.
      This type of oil is suitable for making gasoline, lubricating oil and asphalt.
    • Paraffinic Crude
      For a waxy crude it is customary to measure its cloud point and pour point according to ASTM methods.
      Crude petroleum oil that contains predominately alkanes as contrasted with asphaltic- or naphthenic-base crudes; used as a source of fuels and high-grade lubricating oils.
      the dynamic viscosity of crude oil increased with the increase of paraffinic content in crude oil.
    • Fractions of Paraffinic crude
      Distillate: Gas
      gasoline
      kerosene diesel
      Residue (Fuel Oil): Wax (lubricating oil), Residue
    • Fractions of asphaltic crude
      Distillate : Gas,
      Gasoline
      kerosene
      diesel
      Fuel Oil (Residue): Diesel
      lubricating oil
      bitumen
      Refined lubricating oil
    • Petroleum fractions used in Pakistan
      Petrol
      High Octane Blending Compound (HOBC)
      Compressed Natural Gas(CNG)
      Light Diesel
      Kerosene Oil
      Gasoline
      Furnace Oil
      Asphalt (residual oil)
      Brake Fluid
      Grease
      Transformer Oil
      Lubricating Oil
    • Bitumen & Bituminous coal
      Bitumen: Any of various flammable mixtures of organic liquids (aromatic), occurring naturally or obtained by distillation from coal or petroleum, that are a component of asphalt and tar and are used for surfacing roads and for waterproofing.
      bituminous coal: a dark coal that burns easily with a smoky flame yielding pitch or tar: also called soft coal
    • Liquid fuels for the furnace
      Gas oil
      Heavy fuel oil
      Light fuel oil
      Coal tar fuel
    • Fuels Oils
      Fuel oil is made of long hydrocarbon chains, particularly alkanes, cycloalkanes and
       aromatics.
      Fuel oil is a fraction obtained from petroleum distillation, either as a distillate or a residue.
      The heaviest commercial fuel that can be obtained from crude oil, heavier than  gasoline and naphtha is also fuel oil.
    • Fuels Oils
      Distillate Fuel Oils: A general classification for the petroleum fractions produced in conventional distillation operations.
      used for space heating
      on and off highway diesel engine fuel (including railroad engine fuel and fuel for agricultural machinery)
      and electric power generation.
    • Fuels Oils
      Included are products known as No. 1, No. 2, and No. 4 fuel oils and No. 1, No. 2, and No. 4 diesel fuels.
      No. 1 distillate is a petroleum distillate which meets the specifications for No. 1 heating or fuel oil as defined in ASTM D 396 and/or the specifications for No. 1 diesel fuel as defined in ASTM D 975.
    • Light Fuel Oils
      Streams obtained from distillation and cracking processes .
      Contain a mixture of saturated, aromatic and olefinic hydrocarbons with carbon numbers predominantly in the C9 to C30 range.
      Composition is complex and varies with the source of the crude oil.
      Extremely flammable. Flash Point <620C
      typical boiling range from 150 to 550°C.
    • Heavy Fuel Oils
      viscous liquids with a characteristic odour.
      require heating for storage and combustion.
      used in medium to large industrial plants, marine applications and power stations in combustion equipment such as boilers, furnaces and diesel engines.
      typical boiling range from 350 to 650°C.
      They consist of aromatic, aliphatic and
      naphthenic hydrocarbons, typically having carbon numbers from C20 to C50,
