An oil separates crude oil into its components by distillation. some components are altered <u>by cracking and Reforming.</u>
<u />
The crude oil contains many petroleum products like petrol , diesel , Mobil oil coaltar and many more with impurities So, now it is very important to separated it into components to use all product individually in pure form.
The separation process are based on fraction distillation because all petroleum products have different density and boiling points. All products are separated at different temperature.
