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.
In this session key aspects of coke drum life-cycle management will be discussed, covering the useful life of these vessels from “cradle” to “grave”; important aspects such as supplemental requirements for design and fabrication, specialized in-service inspection, monitoring and assessment tools, pro-active and reactive repairs, will be briefly covered

Join this session to hear the latest on API's 5th edition of Recommended Practice (RP) 751, Safe Operation of Hydrofluoric Acid Alkylation Unit. In this session, we're discussing maintenance from the operator perspective, integrity management and other safety programs for hydrofluoric (HF) acid alkylation units.
In this session we will show the results of a failure in a Mechanical Integrity Program. This track will also discuss event investigation results, along with, lessons learned and path forward, in hopes to enlighten all in the industry.
