Implementing a Refinery Diesel Pool Optimizer Using Neural Networks and Reinforcement Learning

Artificial Intelligence, Advanced Process Controls


Facilitator:
Atique Malik, AIControl LLC

Speaker:
Yangdong Pan, Delek US
Toni Adetayo, Imubit, Inc.

Multi-unit optimization has long been a complex issue in the oil and gas industry. Despite efforts using first-principle models or empirical approaches, challenges persist. However, the emergence of machine learning and AI technologies offers an alternative solution. In particular, AI-based process control technology has shown promise for multi-unit optimization. This session will delve into an example using a distillate system optimizer to understand how these AI models address large-scale optimization challenges and how parent and child models collaborate.

Participants will learn:

  • The strength of the technology and its high flexibility of handling core issues

  • How the technology deals with the availability of individual units, and cooperates with unit controllers from other advanced control technologies

  • How to sustain the technology’s performance and benefits

  • A site-wide AI adoption strategy

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.
