Jenny Hebert and George Yaluris of Albemarle accept the <i>HP</i> Award for Best Catalyst Technology.

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).

Hydrocarbon Processing Awards

<i>Hydrocarbon Processing,</i> the downstream processing sector’s leading technical publication, has announced the winners for its second annual awards.

Viva Energy’s Geelong refinery reduces FCCU turnaround risk

Change involves risk. Many fluidized catalytic cracking units (FCCUs) can be operated more profitably, but changes to achieve more efficient operations can be risky.

Reduce dry gas and coke with a more flexible FCC technology

To meet increasingly stringent specifications for cleaner gasoline and to produce more clean fluid catalytic cracking (FCC) naphtha with lower olefins, a novel FCC technologya for maximizing isoparaffins was developed in the late 1990s. The technology’s principal is based on the formation and conversion of olefins in two different reaction zones.

Additive solutions to SO_x 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_x additives on the market; therefore, to optimize SO_x 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.

Editorial Comment: Celebrating the latest advancements in HPI technology

At the end of this month, <i>Hydrocarbon Processing</i> will honor the latest technological advances in the hydrocarbon processing industry (HPI) at an awards gala.
