March 2024

Background
This project was initiated after several refineries across North America reported issues with jet fuel specification failures due to clay treater fouling. Some reported JFTOT failures while others reported MSEP failures.

This project is currently under the Project Maintenance group while we assess if the issue warrants a stand-alone project.

Milestones as of April 2025

• Information was presented at the March 2024 Open Forum indicating clay treater fouling was reducing clay life to as little as 3 days. See March 2024 Open Forum meeting minutes for details.
  
• Additional refiners (US and Canadian) provided data at the June 2024 Project Maintenance meeting indicating reduced clay change out cycles. See Open March 2024 Project Maintenance meeting minutes for details.
  

• Results of heavily fouled Merox skid liquid samples were analyzed and data was presented at the February Project Maintenance meeting. See February 2025 Project Maintenance meeting minutes for details.
  
• Currently only one refiner is reporting clay treater issues currently. One sample is currently being tested however CCQTA testing is scaling back work since the current issues appear to isolated to only one refinery.
