Optional Gas Treating Seminar

Brimstone is pleased to announce an important half day seminar titled, “Meeting Challenges in Gas Treating – State of the Art” presented by Optimized Gas Treating, a highly respected amine services firm that offers consulting and software for amine treating. The session will focus on:

  1. Enhancing AGE (acid gas enrichment) and TGTU selectivity; and
  2. Heat stable salt (HSS) impacts on design and operation of amine units and sour water strippers.

This optional, add-on session will be held on Monday afternoon from 1 to 5 p.m. in the Salon Burggarten in the Hotel Bristol. The fee for this special session is $200 USD. Attendees can register at the same time they register for the Brimstone Symposium. A detailed description of the session content is shown below. Seating is limited, so register soon!

 

Meeting Challenges in Gas Treating — State of the Art”

This half-day seminar explores two important issues in processing gases containing H2S — (1) achieving maximum selectivity in Acid Gas Enrichment (AGE) and Tail Gas Treating Units (TGU’s) through selection of the best possible absorber internals, and (2) the impact of heat stable salts (HSS’s) on gas treating with amines and on sour water stripping. The seminar uses ProTreat® mass transfer rate-based simulation in a series of focused case studies.

Science of Mass Transfer Rate Modeling in Amine Treating and Sour Water Stripping

The seminar begins with a discussion of the underlying scientific basis for the mass transfer rate approach to separations simulation and how this approach creates a virtual plant. The discussion includes why and how simulation can be most effectively used both in highly detailed design and in rigorously troubleshooting badly-performing process plants.

  • Why and how simulation can be most effectively used in detailed design and in rigorously troubleshooting badly-performing process plants.

Tower Internals for Selective Treating Applications

Acid Gas Enrichment and Tail Gas Treating are used as case studies in understanding how tower internals such as tray design details and packing type and size impact selectivity towards H2S. Proper tray design can result in greatly improved selectivity. The right packing can also be very selective, but if the packing is too small it may plug, and if it’s too big it will fail to provide the right selectivity. How do you find the right size and type for your situation?

  • Uses Acid Gas Enrichment and Tail Gas Treating as case studies to understand how tray design details and packing type and size affect selectivity towards H2S.

  • Achieve astonishingly better selectivity by properly designing trays.

  • Choose the most selective packing and predict random and structured packing performance.

Dealing with Heat Stable Salt (HSS) Contaminants in Amine and Sour Water Systems

One of the most common and treacherous situations in refinery sulfur processing systems is the presence of heat stable salts. Although they can be participants in exacerbating corrosion, they also sometimes have a negative effect on process performance and equally often a very beneficial effect on performance if their level is controlled. No solvent remains in its pristine, as-received condition for long. Contaminants should be allowed for in the design stage, but how—mass transfer rate-based simulation is a possible answer. HSS’s also can drastically alter sour water stripper performance in a negative way. Techniques to properly account for HSS’s during the design and operational optimization stages are furnished in this part of the seminar. Several failed designs will be analyzed as well as shedding light on how to interpret and translate a solvent analysis into a practical model.
