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.

Topic
Casting Quality Issues in HF Alky Valves
HF Alkylation
Over the last few years, there has been an increase in through body leaks on cast HF Alkylation valves. This presentation will review several real life examples of casting failures on valves in HF Alkylation service including cross sections of the failure location. These failures have occurred on both low RE carbon steel and Alloy 400 (M35-1) castings. Some common causes of casting failures will be reviewed including sand inclusions, porosity and varying levels of shrinkage. Common locations of casting quality issues with HF Alkylation valves will be discussed including the bottom bowl area and the body to end flange transition on Alloy 400 plug valves. The presentation will also cover some of the methods that are being implemented in the industry to improve the casting quality of HF Alkylation valves along with efforts to standardize and consolidate requirements for these valves.

Turnaround Bookends Panel: Good Practices for Startup/Shutdown Operations
Turnaround Roundtable
This panel is intended to attract Turnaround and Operational leaders who would like to gain insight on good practices that industry peers are using to prepare and execute SD/ Decommissioning and SU/Commissioning of units for maintenance events. This discussion will also include safe work practices insights for lock out tag out, energy control, blinding or walk the line/job practices that help improve safe outcomes of an event. The panel will also share their perspectives on future opportunities related to transformative technologies and practices for turnaround operations.
