What is decanted oil?
Decanted oil is the heaviest product from a cat cracker. It is also called slurry oil, clarified oil, and bottoms and FCC residue. Depending on the refinery location and market availability, DO is typically blended into No. 6 fuel, sold as a carbon black feedstock (CBFS) or even recycled to extinction.
What is FCC decant oil?
Also known as: cat slurry, cat bottoms, decant oil. FCC slurry is a highly aromatic resid stream produced by the FCC. Typical uses for FCC slurry are: Fuel oil blending – Cat slurry can be blended into residual fuel oil with minimal amounts of cutter stock to achieve the required viscosity.
What is heavy cycle oil?
Heavy cycle oil (HCO), produced from FCC units typically set in the distillation range between 350 to 500 °C, is also composed of highly poly nuclear aromatics, often in excess of 40%, a significant portion of which features tetracyclic and pentacyclic aromatics.
What is vacuum residue?
Vacuum resid is the heaviest of the distillation cuts. It is, literally, the bottom of the barrel. Vacuum resid is the bottoms cut from the vacuum distillation tower. If not upgraded, vacuum resid is blended into either residual fuel oil or asphalt.
How do you calculate the density of crude oil?
Mathematically, density is defined as mass divided by volume. The formula for density is d = M/V, where d is density, M is mass, and V is volume.
What is LCO in oil industry?
Also known as: light cycle oil, LCO. Cycle oil is the diesel range product from the FCC unit. As a diesel blendstock, cycle oil is not very highly valued because of its high aromatics content, which gives it a low cetane. Typically, it is hydrotreated to raise its cetane and then blended into diesel.
What is LCO In petroleum?
Light cycle oil (LCO) is a diesel boiling range product from fluid catalytic cracking units. However, LCO is a poor diesel fuel blending component without further processing.
