What is FCC slurry?
FCC slurry is a highly aromatic resid stream produced by the FCC. Coker feed – FCC slurry can be blended with vacuum resid and used as feed to the coker. Needle coke production – Because of its high aromatics content, FCC slurry tends to form needle-like crystalline carbon structures when coked.
What is FCC in refinery?
Fluid catalytic cracking (FCC) is one of the most important conversion processes used in petroleum refineries. It is widely used to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum crude oils into more valuable gasoline, olefinic gases, and other products.
What is an FCC plant?
Fluid catalytic cracking (FCC) plants are used to convert heavy distillates into lighter ones like gasoline and diesel. The feedstock is primarily vacuum gas oil, often mixed with refinery residues.
How do FCC cyclones work?
Regenerator Cyclones are used to separate catalyst from flue gas created when the carbon or coke is burned with air from the FCC catalyst. They are designed to withstand very abrasive service at a temperature of 1,450 degrees F.
What is importance of FCC and hydrocracker unit in a refinery?
In a refinery, the hydrocracker upgrades VGO through cracking while injecting hydrogen. This yields a high volume of high-quality diesel and kerosene product. This is in contrast to the FCC, which uses the same feed (VGO) but produces more and better-quality gasoline.
What is FCC naphtha?
FCC gasoline – This is a naphtha range material with octane and vapor pressure close to the quality specifications for finished gasoline. This is typically the largest product at around 50% of FCC output. Cycle oils – The FCC produces a diesel range product called cycle oil.
What is the difference between FCC and RFCC?
Fluid catalytic cracking (FCC) is an effective refinery process for the conversion of heavy gas oils to gasoline. RFCC catalysts are designed to be more stable than FCC catalysts because of the higher cracking temperature required for heavier feedstocks.
What is slurry oil used for?
Slurry oil is a heavy aromatic by-product of a refinery’s fluid catalytic cracking unit that forms a small part of global fuel oil supply. Generally, it is mixed into heavy fuel oil as a viscosity cutter. Slurry oil’s low API gravity, however, limits how much can be blended.
What is the role of cyclone in fluid bed catalytic cracking?
Fluid Catalytic Cracking Units (FCC Cyclones) are the principal technologies that enable the critical process within heavy oil refining of converting the heavy oils into more valuable gasoline and lighter products.
What are the uses of FCC slurry 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
Which is the best FCC / RFCC slurry filter?
Mott’s FCC/RFCC slurry Fflters excel at removing alumina-silica and other solids contaminants from main column bottom slurry feeds. With online clean-in-place automated backwashing, our slurry oil filters achieve filtrate quality below 100 ppm total suspended solids.
Why is FCC slurry used for needle coke?
Needle coke production – Because of its high aromatics content, FCC slurry tends to form needle-like crystalline carbon structures when coked. This needle coke is highly valued for manufacturing of electrodes. An important specialty market for FCC slurry is sales to specialized needle cokers that focus on making this product
What is the filtrate quality of slurry oil?
With online clean-in-place automated backwashing, our slurry oil filters achieve filtrate quality below 100 ppm total suspended solids. This ensures the filtered oil can be used for blending or sold as valuable product into other applications.
