Join Brian Rohrback on 10/12/2021 at the Orchid Room, 9:40 AM – 10:10 AM.
A multi-industry consortium got together 8 years ago to rethink how calibrations need to be performed for spectroscopy instruments and analyzers. The priority was on solutions that are non-disruptive, fully utilize legacy systems, and lessen the workload rather than layer on additional requirements. The result is a foolproof, simple approach that can be used with any type of brand of spectrometer, any type or brand of chemometrics, and ensures robust and reliable calibrations.

Join Brian Rohrback on October 5th at 11:00 am – 12:00 pm CST for panel discussion on The Role of Artificial Intelligence in Manufacturing and Petroleum Refining at the 2021 AFPM Summit.
Artificial intelligence and machine learning are inevitable results of the work driven by the consumer side of our economy. The question is not whether it will impact refining and chemical plant operation, but how soon and how long it will take for the benefits to outstrip the costs. The goal is to distinguish between vision and hallucination and to provide some practical guidance for making progress in this complicated set of fields.

The work showcases the power of chemometrics to distinguish oil families and presents explanations for those families based on paleoclimatic changes during deposition of the Miocene source rock in the Santa Maria Basin applying both molecular biomarker distributions and isotope data.

Analytical Separations: Theory, Applications, Instrumentation
Biodiesel is added to diesel fuel in concentrations ranging from 2 to 35%, mostly for the purposes of reducing greenhouse gases. The resulting binary blended fuels (labeled B2-B35) have lowered hydrocarbon and carbon monoxide emissions compared to petrodiesel. Traditional analysis methods utilize gas chromatography (GC) with a long, polar column leading to separation times of thirty to sixty minutes. As a faster alternative, we propose using ultrafast GC (UFGC) to evaluate binary fuels with concentrations ranging from 1-20% with various biodiesel feedstocks (soybean, tallow, safflower, sunflower, camelina, palm, etc). A short mid-polarity column (MXT-50, 4m x 180 mm x 0.2 mm, Restek) was used to provide optimal separation of the saturated fatty acid methyl esters (FAMEs) in the biodiesel while still allowing for retention of the variety of components in the diesel. Several chemometric tools, including Principal Component Analysis (PCA) and Partial Least Squares (PLS), were used to provide group analysis of feedstock type and concentration.
