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.

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.

Increasing Reliability in Cyclic Reformers
Gasoline Processes
For many facilities, cyclic reformers play a pivotal role in refining operations, offering flexibility in upgrading naphtha into high-octane reformate and a continuous source of hydrogen. While cyclic reformers offer a distinct advantage over semi-regen reformers with regards to turnaround timing, this comes at a cost. This presentation tackles key operational challenges and reliability issues, such as iron contamination, ammonium chloride fouling, on-oil exotherms, reactor hot spots, regeneration section corrosion and the functionality of motor-operated valve (MOV) interlocks.
By providing a comprehensive approach to enhancing cyclic reformer reliability, this presentation reinforces the importance of proactive maintenance, process optimization, and robust safety measures. These strategies provide crucial insights to aid operators in maximizing unit performance while minimizing operational risks.
