FCC metal trap additives to process more residue
Most refiners frequently need metal trapping or bottoms cracking additives for residue operations.
FCC operational changes to boost gasoline octane
The fluid catalytic cracking unit (FCCU) is one of the main units providing gasoline with high-octane numbers to the refinery gasoline pool.
Feed nozzle effects on yields and operation of FCCUs
The first-generation, proprietary feed distributorsa had open-pipe bayonets that were located at the base of the wye section/riser.
Additive solutions to SOx emissions in FCCUs
Sulfur oxide additives are typically based on hydrotalcite or magnesium aluminate spinel-type structures. Magnesium alumina is the pickup agent present in the most effective SO<sub>x</sub> additives on the market; therefore, to optimize SO<sub>x</sub> reduction, it is critical to maximize the amount of the critical magnesium component in the fluid catalytic cracking unit (FCCU) in an efficient and cost-effective way.
