Petroleum

1. classified

   • 1.Paraffinic
     • petroleum flows easily and shows a clear hue. Paraffinic oil presents a considerable amount of naphta
   • 3.Mixed
     • Mixture of both types of compounds
   • 2.Naphtenic
     • produced by naphthenes and aromatic hydrocarbons. It is an extremely viscous crude oil, and shows a dark hue.

2. Petroleum or crude oil is a complex mixture of organic compounds known as “hydrocarbons”.

3. Products

   • Gas
     • fuels
       • Home heating
         • diesel engines
           • engine lubricants
             • cream
               • pavement

4. Exportation:

   • Locating the deposits.
     • technicians use techniques to scan the subsurface and produce a 2D or 3D image. Seismic reflection,
       • They look for differents kinds of rocks that contains oil
       • It can be found at Earth’s bottom, where hard rock layers must be drilled in order to obtain it.
     • oil deposits
       • Land
         • at Earth’s bottom, where hard rock layers must be drilled in order to obtain it.
       • sea
         • At sea’s bottom. Crude oil can be obtained by fighting against sea currents and soil.
   • Drilling
     • The method Edwin Drake used to drill oil wells is called cable-tool or percussion drilling. A hole is punched into the ground by a heavy cutting tool called a bit that is attached to a cable and pulley system. The cable hangs from the top of a four-legged framework tower called a derrick.

5. Comes From:

   • formed throughout a long process that spanned millions of years based on plant and animal decomposition.
   • It can be found within “bags” covered by hard rocks.

6. Process:

   • 1.Fractional distillation.
   • 2.Conversion processes.
   • 3.Treatment
   • 4.Formulation and mixing
