Is the capacity of a crude oil barrel is 200litres? when refined how much petrol or Diesel is obtained?

One barrel is equal to 158.76 liters, and the amount of Diesel and Petrol, depends upon the quality of crude oil, being processed and also the kind of refinery process.

There are many differnet crude oil types that will yield a different proportion of diesel. It is also correct that the more complex refineries can convert some of the heavier residue into Diesel to make a higher percentage.





To give you some idea lets pick a middle of the range crude oil for example Brent Crude extracted from the North Sea. In a ';straight run'; scenario i.e. distilled from the crude column only you might get 15-20% diesel. If the refinery had a cracking process and vacuum distillation process then it is possibly to increase this yield by more than double so about 45% absolute tops. This rapidly becomes a very complicated subject because heavier crudes for example from Venezuela may only produce 5% or less and really light crudes from the Caspian Sea can produce 30% straight run.





It also depends on what quality Diesel you require. The higher the quality in terms of Cetane No and Sulphur levels result in a lower yield of diesel from each barrel.
