WORKSHOP 2 – SOUR GAS TREATING |
March 27-28 |
OUTLINE PROGRAMME |
| Principles of mass transfer rate-based simulation.Compelling reasons why a rate model is needed. Competing reactions, phase equilibrium, mass transfer characteristics of trays and packing. |
| Important parameters in acid gas removal.Understanding temperature profiles in absorbers. Under-circulated and over-circulated systems. Regenerator behavior; effect of feed preheating versus reboiler duty on performance, heat integration, managing energy requirements. |
| RMixed amines and physical solvents: process performance with piperazine and other reactive amines, designing a blend to meet treating goals, stripping promoters – case studies showing when to use them and how much to use. Applications in selective treating and acid gas enrichment. Using SELEXOL™/Genosorb®-type solvents to achieve high selectivity. |
Contamination of amine solvents: case studies showing penalties and benefits of heat stable salts, treating with contaminated solvents, making reclaiming decisions, when to reclaim and to what extent, preventing and controlling contamination in amine systems, particulates, hydrocarbons, heat stable salts.
|
| Corrosion in sour gas systems: wet H2S corrosion theory, defending against corrosion, managing corrosion in sour water and amine systems. |
| Amine analysis: what to look for and why. Review of basic terminology with emphasis on meaningfully interpreting solvent analyses. Using a charge balance to dissect and validate an analysis, inherent limitations of common analytical methods. |
| Can MDEA be used effectively to remove CO2? Chemistry and limitations of treating with MDEA, even at high pressure. Case studies showing deficiencies caused by ignoring mass transfer rate limitations in facilities design for treating high CO2 gases with MDEA. |
| Impact of column internals selection on sour gas treating: tray and packing hydraulics, tray jet flood, downcomer flood, tray weeping, tray operating regimes, liquid distributors, redistributors and channeling in packed towers, case studies showing the effect of hydraulics on mass transfer and treating selectivity. |
| Dehydration with mono-, di- and tri-ethyleneglycols. Dehydration challenges of gases with high CO2 and H2S content. |
| Caustic treating for mercaptans and trace acid gas removal. Important parameters will be discussed with an emphasis on chemistry to understand the fundamentals, caustic versus amine treating of mercaptans and H2S, advantages and disadvantages. |
