Explain the process of fractional
Distillation of petrolium & write products.
Answers
Answer:
Here
Explanation:
Fractional distillation is the process by which oil refineries separate crude oil into different, more useful hydrocarbon products based on their relative molecular weights in a distillation tower. This is the first step in the processing of crude oil, and it is considered to be the main separation process as it performs the initial rough separation of the different fuels.[2] The different components that are separated out during this process are known as fractions. Fractions that are separated out include gasoline, diesel, kerosene, and bitumen.[3] Fractional distillation allows a lot of useful products to be made from crude oil, with many environmental consequences for the use of those useful products!
Process
The process of fractional distillation is fairly simple, but is powerful in the way that it separates all the different, complex components of crude oil. First, the crude oil is heated to vapourize it and is fed into the bottom of a distillation tower. The resulting vapour then rises through the vertical column. As the gases rise through the tower, the temperature decreases. As the temperature decreases, certain hydrocarbons begin to condense and run off at different levels. Each fraction that condenses off at a certain level contains hydrocarbon molecules with a similar number of carbon atoms.[4] These boiling point 'cuts' allow several hydrocarbons to be separated out in a single process.[5] It is this cooling with the height of the tower that allows for the separation.
After this rough refinement, individual fuels may undergo more refinement to remove any contaminants or undesirable substances, or to improve the quality of the fuel through cracking.
Answer:
Fractional distillation is a process by which individual components can be separated using heat from a given mixture. The boiling points of each component in the mixture determine the order of separation. Common uses of fractional distillation include the production of distilled water, and gasoline from crude oil.
