Syngas Over the past 14 years, online nuclear magnetic resonance (NMR) analyzers have proven useful in extracting additional profits by reducing the:• Loss of diesel into gasoil• Loss of gas oil into resid• Coke pre-cursors in reformer feed• Product quality give-away in gasoline, jet and diesel. Integrating NMR with regulatory and advance process control will improve yields, decrease energy consumption and reduce analytical loads to improve margins by $2,000 to $10,000 per day for the average 100,000-bpd refinery. Distillate products. Fig. 1 illustrates the 24-hour distillation predictions from one NMR-monitoring process stream from two separate crude distillation uni
