Hosted by Optimised Gas Treating
In sour gas processing, the sulphur plant itself is highly inter-dependent on upstream and downstream gas processing units such as acid gas removal (AGR) and enrichment (AGE), tail gas treating (TGT), and sour water stripping (SWS). Experimenting with full-size production plants to improve understanding of process behaviour can be a career limiting learning process. However, process simulators have become increasingly realistic. With the availability of mass transfer rate based simulation of gas processing, and the recent introduction of a first principles based sulphur plant simulator, it is now possible to convert an entire gas treatment facility into a virtual plant. Today, simulation allows real understanding to be gained by doing precisely what cannot be done in the plant—experimentation. The workshop is designed to dissect and understand several broad aspects of modern sulphur recovery.
The workshop is designed to help you gain more in-depth understanding of Claus-type SRUs and improve their performance through:
- Studying feed preparation techniques in controlling H2S quality, hydrocarbons and NH3 content,
- Controlling combustion air and understand the importance of the air demand analyser,
- Evaluating how tail gas clean-up directly affects SRU performance, and
- Understanding the kinetics of thermal reactions in the furnace and WHB, optimising catalytic converters, sizing and rating sulphur condensers, and dealing with sulphur storage, handing and degassing.
Who Should Attend
The workshop is intended for
- Engineers relatively new to gas treating and sulphur recovery
- Technical managers and engineers engaged in plant design, production, troubleshooting and revamps of process units in acid gas removal and sulphur production
- Process equipment suppliers, particularly of towers used in gas treating and catalyst vendors
A one-half day, hands-on workshop using process simulation software and covering the topics:
- Thermal Reaction: contaminant destruction (NH3, BTEX, hydrocarbons); the evil step cousins – CS2, COS, and trace sulphur; oxygen enrichment; Waste Heat Boiler recombination reactions and heat flux implications
- Sulphur Condensers: equipment design & rating; H2S/H2SX/SO2 solubility; entrainment
- Catalytic Conversion: optimal operating temperature; catalyst selection; COS/CS2 conversion vs. Claus reaction; modelling SOR vs. EOR conditions
- Sulphur Storage, Handling, and Degassing: sulphur viscosity, product quality, H2S degassing
- Tail Gas Clean-up: effect of NH3 and SO2 on quench column and amine system performance; EOR design and operation considerations
A limited number of laptop computers will be provided, restricting the hands-on aspect of the workshop to a maximum of 20 participants.
