Workshop
- Fundamentals of mass transfer rate model (if no introductory seminar is offered)
- Column internals; pressure specifications; columns with multiple sections; and water wash sections; swages; pumparounds & pumparound condensers; internal cooling; types of reboiler specifications; liquid treaters; data needs unique to mass transfer rate-based models
- Forcing convergence - damping and restarts, how and when to use them and what to expect; Simulation results - viewing graphs, interpretation, exporting results and copying to other applications such as Excel, Word, PowerPoint
- Important parameters in amine plants, using and interpreting absorber and regenerator temperature and composition profiles, normal and inverted temperature profiles, approach to equilibrium. Case studies of under-circulated and over-circulated plants
- Mixed amines: process performance with piperazine and other reactive amines, designing a blend to meet treating goals; stripping promoters - when to use them and how much to use.
- Contaminated Solvents: penalties and benefits of heat stable salts, treating with contaminated solvents, making reclaiming decisions: when to reclaim and how much reclaiming is enough.
- Types of column internals, tray and packing hydraulics, tray jet flood, downcomer flood, tray weeping, tray operating regimes, liquid distributors, redistributors and channeling in packed towers, effect of hydraulics on mass transfer and treating selectivity
- Acid gas upgrading (enrichment) for higher Claus plant feed quality and capacity or for acid gas re-injection
- Physical solvents, glycol dehydration
- Corrosion
- Troubleshooting: Case studies of various plant operating problems:
- Fuel gas treater - contamination with heat stable salts and importance of chemistry, over neutralization with caustic, and caustic contamination of an amine system.
- Importance of ionic charge balances and solvent analyses in troubleshooting
- Plant and laboratory data validation
- Case of lost treating performance
- Solvent change-outs on the fly
- A tail gas unit selective amine system
- Closing Comments and Evaluation of Workshop
