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.

Future Energy - Small Module Reactor Technology
Sustainability
The potential of Small Modular Reactors (SMRs) lies in their ability to revolutionize the energy sector with their modular and scalable design. Unlike traditional reactors, SMRs can be constructed in factories, ensuring uniform quality and reducing construction times. While their compact size allows for easier transportation and installation, with the promise of enhanced safety features, lower initial investment, and flexibility to meet varying energy demands. SMR technologies currently under development will be discussed with how they will provide new options specifically for the needs of the refining and petrochemical industries.
Participants will:
- Gain a fundamental understanding of current SMR technologies
- Learn about potential Use Cases for SMR’s in refining and petrochemical manufacturing
- Learn timeframes for SMR availability

Many new facilities were commissioned recently to produce renewable diesel and SAF from renewable feedstocks to reduce the carbon intensity of transportation fuels while taking advantage of state and federal credits. Operating experience in this technology has been gathered by operators and their suppliers. This session will capture some of that expertise and share it with the audience in a traditional Q&A format. An experienced panel of Renewables experts from Operating and Technology companies will answer member supplied questions on operations, technology, reliability and lessons learned. Those in attendance are sure to gain valuable knowledge on this important topic.

Digital Service for Crude Blending and Desalter Operation Using Field-Deployed Handheld NIR Spectrometer
Crude
Facilitator:
Sam Lordo, Becht
Speaker:
Graylon Williams, Nalco Water
Refineries have increased focus on processing unfamiliar opportunity crude oils to improve profitability. However, the introduction of these new crude slates brings uncertainties that can impact refinery operations. One major challenge is crude incompatibility due to asphaltene instability, which affects desalters, emulsion stability, preheat trains and furnace fouling.
For decades, the industry has recognized the importance of tracking asphaltene stability. Suppliers and refineries employ diverse equipment to assess feeds stability including benchtop microscopy and titration equipment. Unfortunately, those methods can require time-consuming offsite laboratory testing.
Now, utilizing a portable, handheld near-infrared (NIR) analyzer, crude oil tanks and other refinery feeds can be assessed for stability and blending suitability with near instantaneous results. NIR spectra from crude oil samples are collected and compared against a database of crudes and crude unit feeds with known asphaltene stability parameters. Asphaltene stability parameters are modeled and reported with a stability assessment.
In the presentation, we will delve into the fundamentals of these available tools, showcasing real-world case studies where they have been successfully applied for crude blends and crude pretreatment to improve and optimize desalter operations and crude preheat train fouling.
