fractional distillation
Petroleum. I'm not sure if it's a distillation process. Diesel is refined from petroleum but I'm not sure how.
Crude oil distillation is followed by the process of petroleum refining. There are many branches leading off into producing diesel, petrol, and the many products that result from the refining process.
Fractional Distillation from petroleum
Fractional Distillation
You can think of petroleum deposits AS a mixture of hydrocarbons. One such mixture which we process and purify is gasoline!
silver reacts with residual gases of the petroleum refining process, oxidises and gets tarnished.
It's called refining the petroleum (occurring at refineries). This process is used in order to separate the crude oil into products such as diesel fuel, heating oil, liquified petroleum gas, kerosene, gasoline, or asphalt base.
