Conference: Galveston 2020

Amine and Sulfur Recovery operations are ubiquitous operations in both refining and gas recovery operations. Yet because these units are viewed as necessary utilities or environmental compliance units, effective monitoring and limited attention to early warning signs of problems are often overlooked until severe issues restrict overall unit and refinery operation.

Further, as the chemistry and basic design of the units differ from the hydrocarbon or gas processing technologies used in the refining or gas recovery operations, the specific nuances and requirements of the unit designs can often be overlooked when designing new or debottlenecking existing units.

This session would consist of the following panel of Sulfur Recovery and Amine SMEs to review the following topics based on actual case studies from actual refinery operations,

  • KPI for Sulfur (Claus/TGU) and Amine Unit Operations
  • Field troubleshooting Field test
    • Amine colors what contaminants or issue are the cause
  • Urban Legends
    • Burning fuel gas to achieve the minimum temperature to destroy ammonia
  • Chemistry
    • Ammonia in the feed to an amine unit.  When does it become and how does one address this?
    • Heat Stable Salts how to minimize and when to regenerate.
  • Unit Design Basics
    • Claus Main Reaction Furnace – Proper Burner Design, Choke Ring vs Checker Wall, where to put pit gas return.
    • Amine System – Cross-contamination.  How amine system design can lead to heavy oil contamination of light products.  What filter to use.

The audience, which should include Technical (Process/Project Engineers), Operations, and Inspection will be presented with a summary of the new technologies, their applications, and limitations.

illustrating several of the topics will be shared with the audience in an interactive manner where the audience will go through the process of identifying and resolving the issue.  The audience will be also be encouraged to share some of their experiences.
