Process NMR Associates and Spin Resonance Ltd have recently completed the construction a small 60 MHz (1.4T) 5mm TD-NMR system that can be utilized to study T1 and T2 characteristics of novel contrast agents at typical MRI frequencies. Here are a few pictures of the magnet. It is based on N42 neodymium-iron discs (120mm diameter x 30 mm deep).

Application for Crude Unit and Downstream Processes: Spectro-Molecular Control for Enhanced Diesel Recovery
NMR Process Systems (NPS) on-line NMR based analytical and process control strategy for enhanced diesel recovery at the crude distillation unit maximizes clean diesel recovery by enabling closer cut point control in the mid-section of the CDU.
Clean Fuels regulations in both the European and American markets have had a substantial impact on a refiners ability to maximize product draws at the refinery front end. Extremely low sulfur requirements for gasoline and diesel have resulted in refiners now being more constrained at the hydro-treaters. Lack of reliable, focused, measurement and control of critical CDU product draws has forced many refiners to significantly undercut these draws in order to ensure minimum error in the final product blends, especially with respect to total sulfur. Depending on a refinery’s crude supply and CDU capacity, a conservative estimate of 300-500+ barrels per day of loss diesel production is typical. With an average of $25-$35 per barrel margin loss, the economic impact of these Clean Fuels Regulations are substantial.
Integrating proven NMR technology with a focused measurement and control strategy enables crude unit operations to cut chemically closer to the hydrotreater constraint limit. The strength of NMR is that it quantitatively and accurately observesthe chemistry of each refinery stream and readily relates that chemistry to chemically dependent parameters such as distillation, cetane, freeze points, etc. The NPS strategy is to cut and control CDU diesel production as closely to the dibenzothiophene distillation limit as possible. Figure 1 illustrates this strategy in terms of both current and proposed NMR based measurements.

Let NMR Process Systems deliver Spectro-Molecular Control to your refinery so that you can achieve real economic and production benefits.
Process NMR Associates – Archives – Gasoline Analysis by NMR and Chemometrics – ENC 1996
Just came across an old presentation on gasoline analysis by NMR and chemometrics with direct comparisons to Mid-IR and NIR. Presented at the Experimental NMR Conference in March 1996….PDF (3 MB)
Conjugated Diolefins Analysis by COSY NMR
Conjugated diolefins are responsible for fouling of many processes in a refinery. COSY NMR analysis can determine the concentration of these species in many processed petroleum product streams….see PNA webs site.
