HF Alky Isobutane Exchanger Bypass Leak
Learnings from Incidents, HF Alkylation
In 2021, hydrofluoric acid vapors were detected by the safety instrumented subsystem (SIS) line of sight laser detection system, which activated both the rapid acid dump system and the fire suppression/unit deluge system. The source of the leak was determined to be the bypass line around the isobutane recycle cooler. Topics discussed: Residual Elements, CMLs for high RE, PMI for high RE, low flow and process deadleg identification.
