Comparative trials with FCC catalyst formulations identified a winner on olefins selectivity and other factors. In this case study, Grace shows the comparative advantage of our catalyst system of ProtAgon 4G/Olefins Ultra MZ. At this integrated international oil and gas company headquarterd in Vienna, the FCCU’s profitability improved due to higher propylene and isobutylene selectivity, improved dry gas selectivity, better bottoms-to-coke yield, improved bottoms upgrading, excellent attrition resistance, and somewhat lower catalyst usage. Moreover, the catalyst change did not affect CO promotion and helped maintain unit particulate and NOx emissions. Read more about the factors that went into the development of this profitable change for the refiner.
The growth in domestic crude production has resulted in new challenges for refiners. Elevated levels of contaminant iron in crude are becoming the norm. Downstream, iron poisoning in the FCCU was once an isolated phenomena, limited to a handful of refiners processing opportunity crudes. Today, more refiners are experiencing the effects of elevated iron in the FCCU. To maintain operating flexibility and profitability, refiners need effective strategies to manage unconventional contaminant metals.
