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.

Topic
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.

Topic
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.
