Polymerisation of alkenes - Essay Example Oil is important because it helps in relaxing. One single sofa has about 60 litres oil (Idem, 2003). The world consumption of oil is rated at 14 billion litres. The industrial process of crude oil results into environmental pollution. One such negative impact to the environment is referred to as the global warming. Carbon dioxide from the manufacture of crude oil is released in the environment. A high accumulation of green house gases like carbon dioxide in the atmosphere leads to the depletion of the ozone layer thus leading to the depletion of the ozone layer, which in turn leads to global warming. The paper explores the chemistry behind the industrial manufacturing process of crude oil. For crude oil to be separated into different chain length, it goes through the heating process up to a relatively high temperature. The involved temperature is set in a manner that the carbon chain length fractions of twenty and below are evaporated to form a mixture of crude oil. This temperature can never be set higher than this level since there would be some risks of ignition of the lighter fractions. The liquid that remains in the fractioning tower is made up of heavier factions. The fractions are passed to a second location, where they are heated to a temperature similar to the initial temperature but at a reduced pressure. The fractions of the heavy hydrocarbon will evaporate. The distillation tower functions by being progressively cooler beginning from the bottom to the top. The fraction of hydrocarbons begins in the form of gas since they would be heated to that point. The gas will then rise to the top part of the tower. The mixture of the gas encounters some barrier that only opens in the bubble caps. The mixture of the gas would then be forced to go through the liquid before it moves upwards. In the fist tray, the liquid will be at a cool enough temperature to get the heaviest fractions of gas that will condense
