The FCC is a flexible machine which is adapting to fulfill the premium gasoline incentive across the USA. This session will discuss how Marathon is enhancing their FCC operations through operational adjustments and advances in catalysis to achieve optimal downstream Alkylation performance. It will also provide an overview of how maximizing alkylate feed, reducing LPG saturates, and optimizing the C4=/C3= ratio from FCC boost the alkylate octane contribution to the refinery gasoline pool.
Join our session to learn about hydrocracker basics. We will discuss how different catalytic solutions can be utilized to generate the most desired products. We will then discuss how APC can further improve hydrocracker economics by utilizing assumed product values while pushing unit parameters to increase profitability.

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.
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.

The intention of the presentation is to share a brief explanation of the Coker operation, how the antifoam is used to control foaming, and the results of a trial in North America using a Low Silicon Antifoam to reduce impact in Hydroprocessing Units & optimize costs.
We will include some information around the questions for the MOC process when the new innovative chemistry is selected and a helpful tool to control foam height at the switch vs true coke outage for reliability purposes.
A trial of the new chemistry was run in several refineries in LA and NA with good results: a reduction of 30-40% of Silicon content in Naphtha and Kero because of the antifoam injection during the Coking cycle. Refiners changed to the new chemistry; savings in the expense costs are expected as chemical usage was reduced vs previous formula with a good control of foaming.
During this presentation, we’ll cover why upstream and midstream use H2S scavengers and to a lesser extent, mercaptan scavenging chemistries. Then, we’ll delve into the different families of scavenger chemistries that can be used and the pros and cons of each, including potential impacts on downstream assets.

A set of case studies are presented by operating companies that discuss Connected Worker initiatives as a vital component of the factory of the future, enabling their organizations to address the challenges of modern manufacturing while reaping the benefits of improved productivity, safety, and efficiency. The Connected Worker, also known as the augmented worker, is seamlessly immersed in their surroundings in an operating facility by the use of a suite of highly advanced digital tool to assist in performing their daily tasks more effectively. Panelists will present their approaches to enabling the Connected Worker in their environment along with what was learned, and benefits achieved.
