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 SOx additives on the market; therefore, to optimize SOx 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.
