Summary
The investigation describes a ruptured line inside a reboiler that caused overpressure, dislodged a pressure safety valve and released liquids, resulting in a flash fire. Improper valve sizing was considered the likely reason for detachment. Emergency shutdown and isolation followed; no personnel were injured. Two noncompliance notices were issued.
