Oil Refining Process Flowchart

A detailed flowchart outlines the intricate process of crude oil refining, beginning with primary distillation that separates the crude into various fractions. These fractions proceed through a series of advanced processing steps including vacuum distillation, cracking, gas reforming, and desulfurization. The diagram clearly categorizes the resulting outputs into major groups such as chemical feedstock (LPG, naphtha), essential transport fuels (gasoline, kerosene, diesel), and other valuable products like heating oil, fuel oil, and coke or bitumen, with typical percentage yields indicated for each.
