Experiences with New Chemical Additives in Refinery Operations
Crude, Coking
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.

Topic
PFAS Regulatory Update and Strategies
Environmental, Crude, Coking
This presentation will explore the implications of EPA's CERCLA and RCRA designations for PFAS in refineries, focusing on the impact to Marathon. Veolia and Marathon will co-present mitigation strategies, from treatment and disposal to non-PFAS alternatives, with real-world examples of proactive solutions. The presentation will highlight the importance of collaboration in adapting to evolving environmental regulations and maintaining operational resilience.
