Acid Runaway (HF and Sulfuric Acid)

Alkylation


In this session we will discuss symptoms, causes, and consequences of an Acid Runaway in an Alkylation Unit and how to recognize and respond to an acid runaway. This track will also discuss lessons learned from acid runaway incidents across the industry.

Participants will: Gain an understanding of what’s an acid runaway, Develop acid runaway monitoring parameters, Develop acid runaway response guidance.

Emerging Technologies for Alkylation

Alkylation


Today’s refiners are looking for newer technologies to product better quality alkylate. This session will review innovative processes, including:

  • The K-SAAT® process, which produces higher quality alkylate using an engineered non-corrosive solid-acid catalyst. The K-SAAT® process eliminates the need for liquid acid catalyst, and is an ideal low cost solution for refiners looking to upgrade their existing Alkylation process. Participants will gain an understanding of how refiners can revamp an existing Alkylation unit to produce better quality alkylate through case studies that illustrate examples of such a conversion and the benefits achieved.

  • The ISOALKY™ Technology, commercialized by Chevron and UOP, which offers benefits (product quality and yields) and economics compared to traditional alkylation technologies. The ISOALKY™ Catalyst is a non-volatile ionic liquid that does not require offsite regeneration. ISOALKY™ Technology can be used for green field plants or retrofit/expansion of existing alkylation units. The first commercial ISOALKY™ Unit has been successfully operating at the Chevron Salt Lake Refinery since January 2021, and the first unit turnaround was completed in October 2024. Participants will gain information on the ISOALKY™ Technology as well as the commercial operation, including turnaround learnings.

Contaminants from FCC to Alky

Alkylation, FCC


Units in the refinery are interconnected and operational changes to an upstream often create challenges for downstream units. We will review how normal and abnormal FCC operations impact Alky feeds. We will also discuss Alky feed specifications and the impact to acid consumption and alkylate quality.

Shielding Trust: The Power of Vigilance and Verification

Walk the Line


Speakers:
Audra Higgins, Phillips 66
Kacey Lopez, Phillips 66
Russell Thompson, Phillips 66

Hear from front line Maintenance and Operations personnel from the Sweeny Refinery as they discuss Walk-the-Line, how supervisor engagement enhances the ability of front-line employees to perform hazard assessments and taking your safety into your own hands. They will highlight tools that have improved their Hazard Identification and Mitigation, leading to three consecutive AFPM DSA Awards.

Attendees will learn:

  1. What walk the line actually means.

  2. Importance of Supervision in influencing proper hazard assessments.

  3. Protect Yourself, trust but verify.

Spent Sulfuric Acid Stability Taskforce

Gasoline Process


Facilitator:
Randy Peterson, Elessent Clean Technologies

Speakers:
Wade Hollman, Phillips 66
Rick Ullrich, Veolia Water Technologies and Solutions

A taskforce was formed as a follow-up to the presentation from PEMEX at the 2023 Summit. A goal of this taskforce is to study what causes some spent acid to be more reactive than typical. Another goal is to develop a simple test to help determine whether spent acid is safe to transport.
