Situation: Design, build and install a sparger for injection of hydrocarbons into a cat cracker
Operating Conditions: The service was hydrocarbons and fluidized catalyst operating at 40 psig and 1050ºF. The wall was 3/8" carbon steel and 4" of refractory with longhorns.
Solution: Team designed, built and installed a special SealTite™ completion plug nozzle onto the cat cracker. The machine holder and sparger (with stellite overlay) were mounted onto the completion plug. The completion plug with sparger then was inserted into the SealTite™ fitting and locked in place with jackscrews. The holder was unlocked and removed, leaving the sparger in operation.
