This is the Shell Sarnia Ontario Canada Reactor/Stripper/Regenerator Modification Project. The Reactor/Stripper sits above the Regenerator at this refinery. General scope includes replacing the Reactor/Stripper including internals and all external piping that could be installed in one lift. The Regenerator Head along with Flue Gas ducting, upper piping, platforms and internal Cyclones was replaced with new components. The lower Regenerator internals were replaced. Construction started 2nd Quarter 2022. I was lead Mechanical Designer on the project. Jacobs Engineering, later to become Worley, was the Engineering Contractor.
