fractional distilation

• what is crude oil

  Crude oil is a mixture of many different compounds. Most of the compounds are hydrocarbons
• Is crude oil is a finite or renewable resource?

  finite
• what is used to separate crude oil

  a fractionating column
• describe how crude oil is seperated using fractional distilation

  1. the crude oil is heated in a furnace till the hydrocarbons in the crude oil evaporates
  2. The vapour then travels up the column
  3. different sized hydrocarbons condense based on their boiling points
  4. long chain hydro carbons condense at the bottom of the column, short chains at the top
• what is feed stocks

  A feedstock is a raw material used to provide reactants for an industrial reaction.
• what are the example of feed stocks made from a fractionating column? Start with the short chain hydrocarbons to long chain

  1. Liquified Petroleum Gas
  2. petrol
  3. Kerosene
  4. diesel oil
  5. fuel oil
  6. bitumen
• what are petrochemicals

  A petrochemical is a substance made from crude oil, via chemical reactions.
• whats the difference between petrochemicals and feed stocks

  the different hydrocarbons in crude oil are all feedstocks, but the useful things we then make from those feedstocks , are all petrochemicals. 
• what are useful materials produced by the petrochemical industry

  solvents, lubricants, polymers, detergents.
