öljänraakaus
Öljänraakaus is a term of Finnish origin that can be understood as the process of refining crude oil. It refers to the complex series of operations required to transform raw petroleum into usable products such as gasoline, diesel fuel, jet fuel, and various petrochemical feedstocks. This transformation is achieved through physical and chemical processes that separate and alter the hydrocarbon molecules present in crude oil.
The primary method employed in oil refining is fractional distillation. Crude oil is heated and introduced
Beyond distillation, other crucial refining processes include cracking, reforming, and treating. Cracking breaks down large hydrocarbon
