Managing hydrogen to achieve ULS targets
Dennis Vauk Air Liquide America LP
Rob Gardner Irving Oil Ltd
David Mercer Fluor Canada Ltd
Nick Hallale Aspen Technology

 

2005 / Q2

To meet clean fuel challenges, refiners must manage hydrogen usage to achieve sulphur reduction targets for 2005 and beyond. Hydrogen network optimisation can deliver significant benefits over traditional approaches

Enhancing SRUs with oxygen-enriched air

Mukesh Mehta CB&I TPA
Aaron Stryk CB&I

2005 / Q2

As clean fuels regulations become more stringent, refiners looking for new ways to boost the capacities of their existing sulphur-recovery units are turning to oxygen-enhancement technologies



More

Selecting materials for FCCUs

Xu Yonggang and Jia Qiliang SINOPEC Luoyang Petrochemical Engineering Corporation

2005 / Q2

Proper material selection for FCCU equipment is critical for long-term reliable operation. Different materials deal with different forms of corrosion, and each material has its advantages and limitations


More

Catalyst addition in ebullated-bed units

Scott Sayles and Jim Bailor KBC Advanced Technologies Inc

2005 / Q2

A simple theoretical approach is available for calculating the catalyst metals content, catalyst physical properties and the effect on catalyst activity. Different catalyst addition rates are reviewed and compared



More

Turnaround preparation Don Turner Jacobs Field Services

 

2005 / Q2

Several work processes have been developed for maintenance turnarounds. Incorporating these processes into a master cost-control and scheduling system ensures materials availability as well as correct staffing levels and timely execution




More

Increasing propylene for the petrochemical market Solly Ismail Engelhard Corporation

 

2005 / Q2

Increasing FCC propylene with shape-selective additives minimises the impact on unit process conditions and equipment. Production of butylenes and isobutene without significant increases in dry gas and coke yield is an added benefit
