Over the past 12 years, Ketjen FCC modeling engineers have simulated over 145 FCC units globally, identifying common challenges that prevent refiners from fully leveraging kinetic FCC models to maximize profitability. These challenges often stem from structural issues in model setup, poor-quality process measurements, or a lack of detailed knowledge about the models. This presentation will highlight 4 to 6 real-world examples, offering insights on how to: 1) avoid common modeling predicaments, 2) quickly identify if problems exist, and 3) implement actionable solutions.

This Lessons Learned session will focus on telling the stories of fatal incidents in Hydroprocessing units to facilitate an awareness and understanding of the different root causes contributing to them. Sharing the lessons learned will help prevent similar incidents from happening again. The presenters will cover a broad spectrum of incidents and their causes with a Q&A discussion at the end.

After more than 50 years of root cause analysis (RCA), you might expect problem solving to be a clear and straightforward process. It’s not. You can find yourself caught in unproductive debates. “Is that a contributing factor, or a causal factor?” “That’s a primary cause, but it’s not the main cause.” The result is frustration, inefficiency, and solutions that allow a repeat of the same problems.
A better approach to RCA is one built on evidence-based cause-and-effect relationships. The steps are simple: define the problem, explain why it happened, and identify solutions to reduce risk. Its focus is on having more reliable work processes, learning, and improving, which helps engage the frontline and minimize blame.
This session will explain the pitfalls of drifting from scientific problem solving and features a case study demonstrating how first-principles RCA leads to tangible improvements in reliability and human performance.
Participants will learn:
Four common errors that arise when explaining why an incident occurred
The biggest misconception about RCA
Why effective RCA does not require any proprietary techniques, terminology, or software
How RCA can be scaled for low-risk incidents and expanded as needed for higher-impact events.
How to reduce “human error” by involving those who perform the work

This presentation will focus on the key performance indicators (KPIs) essential for optimizing delayed coker unit operations. It will examine the influence of feed properties on coke quality and heater fouling, while highlighting strategies to improve heater performance and maximize coke drum capacity utilization. Particular emphasis will be placed on minimizing coke drum outages and optimizing cycle time management to enhance unit throughput and reliability. The discussion will also address fractionator and gas plant performance, with a focus on maximizing liquid recovery, as well as evaluating blowdown system. Collectively, these KPIs provide a comprehensive framework for driving operational excellence and improving overall coker profitability.
Fluid Catalytic Cracking technology provides an elegant and flexible solution to meet refining and petrochemical demands but concurrently carries notable challenges. Among these challenges are contaminants produced in the process, notably particulate matter, SOx, NOx, and CO, which have potential to result in air quality emissions from the flue gas stack. This session will describe the formation mechanisms and summarize available control technology to manage emission of these species.
