Over the last few years, there has been an increase in through body leaks on cast HF Alkylation valves. This presentation will review several real life examples of casting failures on valves in HF Alkylation service including cross sections of the failure location. These failures have occurred on both low RE carbon steel and Alloy 400 (M35-1) castings. Some common causes of casting failures will be reviewed including sand inclusions, porosity and varying levels of shrinkage. Common locations of casting quality issues with HF Alkylation valves will be discussed including the bottom bowl area and the body to end flange transition on Alloy 400 plug valves. The presentation will also cover some of the methods that are being implemented in the industry to improve the casting quality of HF Alkylation valves along with efforts to standardize and consolidate requirements for these valves.

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.

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.
The FCC is a flexible machine which is adapting to fulfill the premium gasoline incentive across the USA. This session will discuss how Marathon is enhancing their FCC operations through operational adjustments and advances in catalysis to achieve optimal downstream Alkylation performance. It will also provide an overview of how maximizing alkylate feed, reducing LPG saturates, and optimizing the C4=/C3= ratio from FCC boost the alkylate octane contribution to the refinery gasoline pool.
During this prsentaion we will define good practices for
the prevention of explosive mixture formation that could result from various causes in the FCC.
