Worldwide Refinery Processing Review (Quarterly Issues)
FCC AND CRUDE DISTILLATION
Publication date:4Q 2008
Recent fluid catalytic cracking and crude distillation technology advances, technical challenges, and R&D work. The operation of these two primary processing units will be integral to the production of gasoline and other distillate products in the refinery.
In the fluid catalytic cracking section, new products and topics covered include:
- Recent developments in the areas of commercial processes and catalysts designed to crack gas oil;
- The new MILOS (Middle Distillates and Lower Olefins Selective) process from Shell Global Solutions;
- Albemarle's new gasoline olefins reducing additive IsoZOOM;
- UpgraderMD and CoralMD cracking catalysts by Albemarle to maximize LCO;
- Grace Davison's BX-450 bottoms upgrading, LCO maximizing additive;
- Comments on the usefulness of catalyst additives, including multi-additive injection;
- Guidelines for regenerator design;
- Updated information on startup and emergency shutdown procedures;
- Operating tips to increase LCO yield;
- Commercial and emerging hardware advances (feed injectors, catalyst coolers, etc.) to improve operations;
- Patent disclosures include a dual-riser process to increase gasoline yield by converting LPG; P-containing zeolites for increased light olefin yield; Zn-containing catalysts/additives for FCC gasoline sulfur reduction; the use of high-metals fish oil for upgrading in an FCCU; metals-trapping compositions containing Ba; processes to reduce CO2 emissions in the FCCU, including the use of gasification; naphtha recycle schemes to increase gasoline octane;
- Updated information regarding FCC installed capacity and recent and completed construction projects.
In the crude distillation section, new products and topics covered include:
- Review of the crude products market including a close up look at diesel vs. gasoline supply, demand, and capacity;
- Updates on commercially available crude distillation technology from Foster Wheeler, KBR, Shell Global Solutions, and Total/Technip-Coflexip;
- Uhde's proprietary vacuum distillation technology;
- Summary of available advanced process control devices and process models, simulators and analyzers;
- Alternative distillation configurations and novel equipment for improved energy efficiency;
- Feed flexibility to process heavy and high TAN crudes, biofeeds, and NG condensate blends;
- Strategies to limit corrosion in CDU equipment;
- Maximizing specific product yield with operation modifications;
- Internals selection recommendations;
- Fire prevention and other safety tips;
- Recent R&D work and patents issued regarding hardware, process configurations, coking/corrosion inhibitors, advanced process controls, and alternative feed processing; and
- Updated information on worldwide installed capacity and recent and completed CDU construction projects.
