With social distancing rules in place, our catalyst removal robot, CAROL, kept a refinery turnaround on track by reducing the amount of people needed on site.
Removing spent catalyst from a reactor is labor intensive and high risk. It can take up to eight people working in a confined space anywhere between three to 48 hours to complete. Throw in social distancing, and it becomes even more difficult to manage.
Social distancing means less people onsite
One oil refinery in North America faced putting their shutdown, turnaround and maintenance work on hold indefinitely because its local social distancing requirements meant less people were allowed on site.
"We reduced the crew size by two and demonstrated that our robotic catalyst removal technology provides a better alternative to manual catalyst unloading."
Back in 2019, the refinery piloted CAROL to remove catalyst from a chloride treater and saw how it can be used to limit human entry in hazardous vessels. With social distancing now in place, CAROL was used again to remove catalyst from the refinery’s naphtha hydrotreater, at an average unloading rate of 5m3 per hour.
CAROL reduces the number of people needed on site
Without CAROL this would have been more challenging to complete while still adhering to social distancing. We reduced the crew size by two and demonstrated that our robotic catalyst removal technology provides a better alternative to manual catalyst unloading.
