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.
More residue processing in FCCUs
Resid units have more than 2 wt% Conradson carbon residue (Concarbon) in feed and more than 5,000 parts per million (ppm) of nickel (Ni) and vanadium (V) on equilibrium catalysts (Ecat).
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.
