We are producing petroleum products in the current environment in which emissions reduction is demanded amidst rising consumer demand. The panel discussion will focus on safe operation and optimization of process fired heaters, including limitations with existing technologies to reduce emissions, and challenges with emerging technologies, e.g., hydrogen firing and electrification.
The CSB will discuss its investigation of the November 19, 2023, fired heater tube rupture at a refinery in Martinez, California. The incident occurred during the initial startup of a renewable diesel hydroprocessing unit, resulting in a fire that seriously injured one employee. Topics will include fired heater safe operating limits, worker proximity to fired heaters, safety instrumented systems that detect low process flow into fired heaters, burner operation, valve misalignments, and corporate oversight.
Participants will: Gain an understanding of both the process-side and combustion-side causes that contributed to the tube rupture; Identify potential deficiencies that may exist at their own units; and Review the CSB’s industry recommendation to API for suggested revisions to API RP 556 (Instrumentation, Control, and Protective Systems for Gas Fired Heaters).

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.
