The production of bitumen typically involves the refining of crude oil. The process starts with the distillation of the crude oil at high temperatures to separate it into different fractions, such as gasoline, diesel, and heavy fuel oil. The heavy fuel oil is then further processed to remove impurities and light components, leaving behind a heavy, viscous residue that is known as bitumen.
There are different methods used to produce bitumen, such as the "air blowing" process, where air is blown through the heavy fuel oil at high temperatures to remove impurities, or the "vacuum distillation" process, where the heavy fuel oil is heated under vacuum to remove impurities.
The production of bitumen can have a significant environmental impact, including the release of greenhouse gases during the refining process, and the potential for spills and leaks during transportation. Therefore, it is important for companies to implement sustainable practices and comply with regulations to minimize the negative impact of bitumen production.
largest bitumen production manufacturing unit in the world is likely to be owned by one of the major oil and gas companies, such as ExxonMobil, BP, or Shell. These companies have significant refining and production capabilities, and they often have multiple manufacturing units in various locations around the world. Additionally, state-owned oil companies like Saudi Aramco, National Iranian Oil Company (NIOC) and Gazprom Neft, China National Petroleum Corporation (CNPC) also have large bitumen production facilities. The exact location and capacity of the largest unit may vary depending on the source of information and the specific criteria used to define "largest."
