The diagram illustrates how a variety of oil-based products are manufactured by refining raw oil. In general, there are 8 types of oil created from treating natural oil inside a container whose temperature ranges from 25 to 350 degrees Celsius. It is worth mentioning that the end products’ features, such as boiling point, volatility, ignition chance, and flow rate, vary accordingly to their molecules’ size. As the unprocessed oil enters the tank, it is heated up at numerous levels of temperature. The maximal temperature of the container causes the oil to become residue that boils at above 600 degrees Celsius and is utilized as bitumen for pathways and roofs. Dropping to the next rank, fuel oil, whose evaporation mark is at between 370 and 600 degrees Celsius, is created to power ships, industrial areas, and heating zones. In the 2 subsequent magnitudes, lubricating oil and diesel boiling from 300 to 370 degrees Celsius and from 250 to 350 degrees Celsius respectively are used as material for polishing and waxing, and diesel fuels sequentially. Following this, Kerosine and Naphtha can be produced at the fifth and sixth rank consecutively; the former boils within a range of 175 to 325 degrees Celsius and is applied in the airline industry as well as commodities like lighting and heating, while the latter vaporizes from 60 to 100 degrees Celsius and is opted for by the chemical-related sector. In the second to last grade, regular petrol, which boils between 40 to 205 degrees Celsius, can be made to power automobiles. Finally, the last stage turns the oil into refinery gas that evaporates at below 40 degrees Celsius and is canned for cooking purposes.
