"Clam Shell" Prevents Regenerator Overhead Flu-Gas Line Failure

Recently, a Mid-West refiner contacted Senior Flexonics Pathway regarding a leaking FCC overhead flu-gas expansion joint to discuss a temporary repair during the unit shutdown in thirty days.

An On-Site Service engineer was dispatched to the job site to evaluate the feasibility and safety for working on the unit. As a result of inspection the “Clam Shell” technique was discussed and agreed upon, however the design required modification. Engineering design drawings were finalized and submitted for quotation.

The situation changed; what initially was presented as a non-emergency need, became an expedited requirement to prevent complete unit failure. The situation now required an on-line “Clam Shell” procedure with elevated system temperature and high wind....a dangerous situation.

Within days the design was approved, hardware was manufactured, shipped and further the “Senior Flexonics Pathway On-Site Team” had completed the installation of the “Clam Shell” under adverse conditions.

According to Senior Flexonics Pathway’s On-Site Service Product Manager, “We had our doubts about whether or not this could actually be done. However, close coordination of the engineering, manufacturing and On-Site Service team resulted in another satisfied Senior Flexonics Pathway client.”
