Fractional distillation of crude oil essay

Fractional Distillation of Crude Oil Fractional Distillation of Crude Oil 7 July Chemistry Crude oil is a naturally occurring, unrefined petroleum product composed of hydrocarbon deposits. It is a fossil fuel, meaning that it was made naturally from decaying plants and animals. Crude oils vary in color, from clear to tar-black, and in viscosity, from water to almost solid. Crude oil can be refined to produce usable products such as gasoline, diesel and various forms of petrochemicals and as such, are a useful starting point for many different substances.

Fractional distillation of crude oil essay

You basically heat crude oil up, let it vaporize and then condense the vapour The various components of crude oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components.

Because they have different boiling temperatures, they can be separated easily by a process called fractional distillation.

Discussion

The steps of fractional distillation are as follows: You heat the mixture of two or more substances liquids with different boiling points to a high temperature.

The mixture boils, forming vapor gases ; most substances go into the vapor phase. The vapor enters the bottom of a long column fractional distillation column that is filled with trays or plates. The trays have many holes or bubble caps like a loosened cap on a soda bottle in them to allow the vapor to pass through.

They increase the contact time between the vapor and the liquids in the column and help to collect liquids that form at various heights in the column.

There is a temperature difference across the column hot at the bottom, cool at the top. The vapor rises in the column. As the vapor rises through the trays in the column, it cools. The substance with the lowest boiling point will condense at the highest point in the column; substances with higher boiling points will condense lower in the column.

The trays collect the various liquid fractions. The collected liquid fractions may pass to condensers, which cool them further, and then go to storage tanks, or they may go to other areas for further chemical processing. Why is the mixture separated? What are the components used for?

Why is Mixture Separated? Below is a list of separated components and what they are used for: Petroleum gas Used for heating, cooking and making plastics.

Commonly known by the names methane, ethane, propane, butane. Naphtha or Ligroin Intermediate that will be further processed to make gasoline.This process is called fractional distillation.

Fractional distillation or petroleum refining is the process of separating crude oil into different components based on their hydrocarbon chains.

Crude oil is separated into fractions by fractional distillation. The fractions at the top of the fractionating column have lower boiling points than the fractions at the bottom. All of the fractions are processed further in other refining units.
