Explosion at hydrogenation unit

Published on 04/01/24 197 Views

A rupture of a pipe elbow in high pressure and high temperature service in a hydrogenation plant was followed by a release and ignition of hydrogen. The construction material of the elbow was carbon steel which is not a resistant alloy and prone to high temperature hydrogen attack (HTHA) at mentioned conditions.

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?
