Gas explosion in a cracking unit

Published on 19/02/24 178 Views

During start-up of a Hydrogen Cracking Unit, the liquid level in the High Pressure (HP) separator disappeared. Gas breakthrough to the Low Pressure (LP) Separator caused over pressure and a rupture. The gas cloud ignited violently.

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?
