RESIDUUM
Value in leftovers
Crude oil is mostly composed of chains of hydrocarbons of different lengths which serve a plethora of uses. They are separated through fractional distillation in oil refineries into different batches of hydrocarbons with similar properties. Residuum is a residue from crude oil that remains after distilling off all but the heaviest components. Gasoline accounts for the largest share of total petroleumproducts produced each year.
- Residue from crude oil after distilling off all but the heaviest components, with a boiling range greater than 1000 degrees Fahrenheit is called Residuum.
- Asphalt/Bitumen – used for roads and roofing
- Lubricating Oils – used to minimise friction, heat and wear between mechanical parts. The most common type of lubricating oil as they are an inexpensive by-product of oil refining.
- Waxes – can be used in candles, foods (chewing gum and cheese wrapping), cosmetics and in waterproof coatings.
- Road Oil – Any heavy petroleum oil, including residual asphaltic oil used as a dust palliative and surface treatment on roads and highways. It is generally produced in six grades from 0, the most liquid, to 5, the most viscous.
- Asphalt – Transported by barge or rail from the supply source to the terminal site. It is then pumped from the barge or railcar to the storage tank.
- Bitumen – Transported at high temperatures up to 250°C in independent tanks supported by means of special methods.
- Wax – Shipped in bags, barrels and cases.
- Infrastructure.
- Construction.
- Engineering.
- Cosmetics.
