On-line octane monitoring at the blender offers substantial advantages in reformulating gasoline and minimizing octane giveaway'. Accurate, real-time measurement of octane number allows rapid adjustments to component feed streams, compensating for variability in the rest of the refining process. With tighter control of the blending operation, less off-spec product is produced, which is particularly important when blending directly into a pipeline. In blending to tankage, less reblending is required to achieve the desired octane specification, which increases both efficiency and equipment utilization. Once tighter octane control is achieved, the refiner can shift octane number targets closer to minimum specifications, thereby reducing octane giveaway. The paper describes on-line octane measurement; remote sensing spectrophotometer; in-line application; principles of operation; instrument calibration; technical performance; tangible economic savings; and future expansion.
