Conference: Rio de Janiero 2014

One month after the installation of the Flowserve FFA with tensiometer on the coke drums at the YPF Lujan de Cuyo Coque II plant, the plate and bolts of the crown pulley system collapsed and the bolts suffered plastic deformation. As a result, the auto-shift tool, stem, rotary joint, and crosshead fell into the drum during decoking. This collapse was due to miscalculations in the new force diagram. This case study and lesson learned will be examined and discussed.
