Debutaniser drain line failure

Published on 06/05/25 96 Views

During the restart of a fluid catalytic cracker after a power failure, a hydrocarbon vapour leak in the unsaturated gas plant led to a fire and explosion, caused by fatigue cracking and mechanical overload in the reboiler transfer line.

Ask yourself and your crew:

  • How can something like this happen here (e.g. on our site)?
  • What safety measures (i.e. procedures, controls/barriers) do we have in place to mitigate the risk?
  • How do we know the risk controls/barriers are working?
  • What improvements or changes should we make to the procedures, controls/barriers, or the way we work?
