| Refocusing on refinery profit |
Simon Calverley, KBC Process Technology Ltd |
2004 / Q1 |
Value-generating strategies must be balanced between profit focus,
yield constraints and cost savings. Techniques presented here
consider increasing profit from yields, balanced against energy
costs.

| Improved control of fluegas emissions |
Jeffrey Sexton, Marathon Ashland Petroleum
Nicholas Confuorto, Belco Technologies Corporation
Michael Barrasso, BOC Process Gas Solutions |
2004 / Q1 |
A proprietary selective low temperature oxidation technology
combined with a wet scrubbing system, was applied to a refinery's FCC
unit regenerator fluegas, resulting in maximum NOx reduction with no
loss of SOx scrubbing performance.

| Balancing octane and hydrogen with ULS fuels |
Jay Ross, Axens North America |
2004 / Q1 |
Options for improving older, semi-regenerative catalytic reformers
and new CCR based reformers, combined with more effective
isomerisation, allow refiners to process straight run and cracked
stocks while adding more octane to the gasoline.

| Using process technology to increase clean fuel yields |
Vasant P Thakkar, Tom N Kalnes, Terry L Makrer, UOP LLC |
2004 / Q1 |
A new approach to the treatment of FCC feed that increases ultra low
sulphur diesel yield is shown in an Asian refinery case study.
The method breaks the link between hydrogenation and cracking functions
and offers a three-year payback.

| Approaches to alkylation: a world review |
Pamela S Pryor, Stratco. |
2004 / Q1 |
Developments in alkylation technology are being influenced by many
factors - not least, fuel specifications - and at a time when many
refiners are considering conversion of HF units for safety reasons,
alkylation capacity must be increased.

| Justification of online optimisation |
Lee Turpin, Aspen Technology Inc |
2004 / Q1 |
Defining the optimisation problem and creating a computer model to
generate benefits in different scenarios will result in a reliable
estimate of what is achievable through the implementation of online
optimisation.
